Feminism And The Feminist Movement Essay - 1292 Words

The feminist movement came to fruition during the early 20th century. Over all, the push for women s suffrage and rights was strong, but further enhanced by leaders like Alice Paul and Jane Addams. The idea of equal rights for all was further scrutinized and contested after civil rights were granted to former slaves. Women began to push for similar equality as illustrated through the feminist movement. The feminist movement became very large and sprouted subsections, one being a subsection of feminism known as social feminism. This branch of feminism was more interested in social rights and used suffrage as a tool to obtain these rights. The question that arises from this idea of a more specific section of feminism becomes: does social feminism qualify as feminism in its truest form? Does social feminism embody the same ideas and morals of the feminist movement? In general, does social feminism count as feminism? Some people question the validity of this brand of feminism. I believe this section of feminism qualifies as feminism nonetheless. To examine this, we must first accurately define social feminism and feminism as a whole, before we can actively compare them. First, let us address the meaning of feminism as the overarching category, in which several specific divisions of feminism fall. Feminism is an extremely simple concept to grasp, if one believes in equal political, economic and social rights for men and women, then they can be classified as aShow MoreRelatedFeminism And The Feminist Movement Essay1672 Words   |  7 PagesThe feminist movement has transformed over the past century through the strength of thousands of women who were willing to put their lives and reputations on the line to fight against social injustice.

Graduation Speech On American History Class - 1996 Words

In August of 2015 I came in to my American history class not knowing exactly what I was getting my self in to , I mean the last time I took American history was my 11th grade year in high school in 2009/2010. After meeting with my new Professor and my classmates , I knew I was up for a run in this class, but I was completely wrong I end up loving it. My team was great! we worked as if we knew each other for years , when in reality we just met and we know maybe after this class ends we might not run in to each other again. The experience is worth taking with us ,where ever we may go .My topics may not be word for word what was said but every one learns differently and they pick up different information while being told the same thing.†¦show more content†¦To begin , many times we feel that if a person has done us wrong we need to do them the same wrong, if not worst. Morally that just make you just as bad as the person who initially had done you wrong. I say this because s ince our ancestors had went through a rough time fighting and dealing with the whites for respect, we got that information and instead of using it to better our selves, we rather us it to justify why we are hurting each other. Some of us have so much hate for the whites that if we see a innocent one getting killed/hurt we would just walk by. we are not the product of our past and we need to learn to stand up for what is right ! it does not matter who you are helping or defending , it does not matter what their ethnicity is , we are all human and if something is not right we need to stand up together as a union and clarify that. the problem shouldn’t be against each other , it should really be against the unfairness of the government who Is the real culprit against us. secondly , I am of African decent, the slaves that was being killed, abused and mistreated could have been my great aunt, grandma, or uncle, it happened to them when it was illegal but now its happening t o us illegally but legally if that makes any sense.

Macro Free Essays

International trade is an economic phenomenon is a strategy that has taken the experiences of many countries in the world.   Between joining and not joining globalization that promotes international trade few will disagree that joining is the better option. This paper seeks to analyze and discuss the manner that greater international trade benefit or hurt the US economy, by identifying likely sectors which will benefit or suffer from expanded international trade, the good or bad reasons for expanding the NAFTA to into the Central American Free Trade Agreement (CAFTA) and finally to make a conclusion in sum, whether   expanded international trade is really to be a good or a bad thing for the United States. We will write a custom essay sample on Macro or any similar topic only for you Order Now In so discussing the to topics, the paper incorporates in detail, five of the concepts from Economic Concepts section. Analysis and Discussion: Expanded international trade aims to promote free trade among nations. For the USA, having the NAFTA and CAFTA as just examples of more definite agreement between or among nations to promoted the trade between or among them.   The WTO is actually a bigger organization that promotes the same purpose. The seeming aim therefore of free trade agreements and America under the NAFTA and CAFTA may have other reasons that US has in mind but for the purpose of this paper, the economic benefits for the US as simply undeniable. The greater international trade and the US economy: Greater international benefit rather than hurt will go to the United States because the United States could produce more than it consumes.   It is being net producer should have been reflected in its trade balance which should have reflected a Surplus Trade Balance but over the years the United the states have always bee in trade deficit†¦ What makes in interesting for America is that despite the trade deficits over the years since it has imported more than it has exported, its gross domestic products over the years have still been increasing over the years. Viewed from the whether its people have benefited from the high GDP over the years, it could be argued that whether the trade balance is surplus or deficit, it is favorable to the United States. As how does this happen, could still be explained   the fact that many countries make investment in US dollars in term of US stocks and bonds and even in currency.   This reaction of countries seems to put the US almost always in a better position. The net effect for the US despite the trade deficit is the gains from as translated in terms of better foreign exchange as against other countries. Again on this angle, although strong dollar as against other foreign currencies would have made US in a better position, devaluating the same could still result to the US still winning the net effect of things. On this note, Samuelson (2004) said that a sliding dollar would have three possibilities:   The first one is that the United States wins and no one else loses if a falling dollar incites the â€Å"U.S. economy by increasing exports and restraining imports.† This will have the effect of Surplus industrial capacity which will keep the inflation low. Samuelson however believes that under this scenario, Europe and Japan don’t suffer much, because the ongoing global economic recovery gathers strength and cushions export losses The second possibility is for the second, the United States and China to win while Europe and Japan lose. This happens because China keeps its currency, the renminbi, fixed to the dollar, and that it also gains competitive advantage when the dollar drops. This is further supported by the fact that China stabilizes the renminbi by investing surplus dollars in U.S. Treasury securities rather than selling them for local currency.). This however will depress exports of Europe and Japan and destroys their economic recovery and then protectionism rises.   The third although possible to happen be remote to happen that is the dollar â€Å"crashes† and that everyone loses. This happens when foreign investors dispose of their U.S. stocks and bonds, as values weaken in terms of their currencies which will trigger massive selling (Samuelson. 2004) As to how the US does it depends on it monetary policy. The US government through the Federal Reserve Bank can influence the foreign exchange market in the world because of the bigness. Using the power of the Reserve Bank, it can increase interest rates hence attracting many holders of other currencies to buy the US dollar and this will again put the value of the US the dollar stronger despite fact that the US has have may trade deficits in terms of more imports as against its exports. The sectors that will get affected by expanded international trade: There are sectors that benefit and some which will suffer from the expanded international trade. To prove such effects, it is was reported that thousands of US jobs were lost due to NAFTA. Scott and Ratner (2005) blamed the rise in the U.S. trade deficit with Canada and Mexico through 2004 for the lost of more than a million since NAFTA was signed in 1993. Jobs displacement occurred in every state and major industry in the United States and that more than half those lost jobs were in manufacturing industries.† The US may have lost in terms of jobs but it may have won in terms of more investments made in the US and in terms of cheaper goods that have entered and the US where its citizens benefited. Expanding the NAFTA to into the Central American Free Trade Agreement (CAFTA): The issue of whether I would be in favor of expanding the NAFTA into the CAFTA appears to depend on what is the purpose of this organization.   The main issue is whether free trade is better for America.   Again on the basis that America produced more than it consumers it is always better to for America to expand NAFTA to CAFTA. Zoellick (2005) said that if CAFTA is voted down, the region’s poor in Central will not improve their lot but instead, a door to upward mobility will be slammed shut. The US is doing not only free on economic reasons but also for political reasons since it believes that by generating employment it lessens problems to society. In sum, expanded international trade is a good for the United States: Boyes, et. al (2003)   said that the US need to be the leader in strengthening the world trading system to promote freer, fairer trade and consequent efficiency gains. Most urgent is for the U.S. to improve its diplomacy within the Doha Round of the ongoing World Trade Organization talks. They even recommended that the U.S. should make concessions to developing countries in agriculture and in intellectual property relief for critical medicines so as to successfully extend and improve the more important multilateral system under a free trade. By so adopting and other public policy actions, Boyes, et. al (2003) believes that US will maintain its long-term strength in its economy.   By so adopting freer trade as a rule for the US, it necessary has to turn its back against protectionism and this is the antidote to freer trade.   Boyes, et. al (2003)   explained that â€Å"protectionism and isolationism aim to maintain advantage in particular industries and professions, but other nations can and have emulated and bested the U.S. in selected and targeted areas, and they will continue to do so.† They also believe that â€Å"the strength of the U.S. is not to found in isolation from globalization. The nation’s strengths are instead its ability to adapt to change, its ability to attract foreign capital, and its ability to attract the best and brightest from across the globe.† Conclusion: We have found that the US will benefit more from greater international trade than not joining than not joining. The simple of joining international trade is the fact that it produces more than it consumes.   There is however some sectors that will likely benefit and some which will suffer from expanded international trade because it could not be that America monopolizes all the knowledge in the world.   As it opens its economy, there are industry sectors where America is not good at but it employs so many people. When we say, America is not good at certain industries, we are saying that America is simply not efficient economically that other nations are simply better than it that America could acquire it at a lower cost, hence it should leave America to source the industry outside and instead concentrate on industry where it is good or in industries where is has potential for growth. The industries that it is good are on agriculture while an industry where it is not good at is on services of some professional like those of nurses. Since free trade is better to America as a rule, expanding the NAFTA to into the Central American Free Trade Agreement (CAFTA) must be deemed to be a better option. In sum, I believed that expanded international trade is to be a good thing for America. Protectionism is no place in America. Its democratic government would be inconsistent to adopt the same since democracy means freedom and freedom means freedom not only to vote in elections but also freedom to excel where its people have the capacity. The US is very reach to lose many things in free trade if one would look at it. Hence it is difficult to see why other developing nations like those in Central America would fail to see the benefits of free trade. References: Boyes, et. al.

Benefits of Cloud Computing Free-Samples for Students- Myassignment

Question: Explain the main concepts of Cloud Computing and why you think that a move to the Cloud could be good for SoftArc Engineering. Answer: This report deals with the cloud based office automation provided for all the civil engineering employees in SoftArc Engineering. The cloud computing lets the SoftArc Engineering employees to utilize the office-based applications like email, word processors, and spreadsheets from distant location. These applications are hosted in the secured data center retrieved by means of network connection. The cloud-based approaches for offering office automation applications include On-Premise Applications and Software as a Service (SaaS). The Hosted Application approach delivers provisions for online accounting, CRM, and industry specified applications. The SaaS approach provides an employee with access to common office applications through web-based interface. Approach Benefits Issues On Premise Applications 1. Easier to use and access. 2. Reduces the physical cluttering without the requirement of hard storage devices. 3. It provides room for development and improves the business productivity. 4. It is stable and decisive. 5. Low Capital Expenditure. 1. Loss of Control. 2. Restricted functions. 3. Restricted Bandwidth. SaaS 1. Maintenance cost of multi-resident applications is less and it is cost-effective. 2. It is Reliable. 1. Security Issues. 2. Compliance problems. 3. This approach encounters some performance issues when compared to the applications executing on local system. I recommend using on-premise software for SoftArc Engineering organization. The on-premise applications are downloaded, installed on the servers, and is provided the license. This is particularly advantageous in larger organizations like SoftArc that requires high security and safety of the data. The on premise applications are owned by the company itself and the amendment of the software is performed at convenient time. Moreover, it can be personalized by the owners without affecting the employees of the enterprise. This report illustrates the problems caused by immigrating the web infrastructure of SoftArc to an IaaS in public cloud. The major distinctions between these solutions are presented from various perspectives: Based on Software: On premise: The configuration complications will be increased if the total number of employees or endpoints is increased that requires additional licences. IAAS: Here, the user can procure the flexible Service Provider Licensing Agreement (SPLA). This results in the flexible licensing options given based on node cost per month or per-user basis (Zhang, Berre, Roman, Huru, 2009). Based on Assistance: On Premise: The exaggerating complication of storage, servers, and the software results in the user investments for expertise assistance team. IAAS: The IAAS providers give assistance to the users, and hence the maintenance cost is comparatively lesser than on-premise solutions. Access: On Premise: In localized network, connection to the infrastructure is sometimes affected. The remote sites based on that location may have only restricted access. IAAS: The IaaS solutions are located within customized data centres with various network levels; the redundancy exceeds the on-premise servers. Challenges of drifting to Infrastructure As a Service (IaaS): Here listed are the challenges encountered during migration: Supplying Provisions for enough Bandwidth Handling mental pattern transition Devising system downtime Handling actual dependency configurations Common database transition problems Compatibility verification concerns on virtual machine communication Security Issues Applications Compatibility Executing and administering applications Handling disaster recovery This report examines the appropriate cloud computing model for SoftArc enterprise. IaaS PaaS SaaS It lets users to access their own infrastructures like computers, storage, and resources It removes the infrastructure away from the user but offers a platform for application development. This model offers access to the software to the users in on-demand method. The user can select from either a single application or a software catalog. Recommended Cloud model for SharePoint The incorporation of SharePoint online as PaaS, IaaS, or SaaS varies according to the requirements of the business. A SaaS cloud model is suitable for accessing off the rack SharePoint applications. On the other hand, the pliability of the PaaS model is needed to develop the cloud applications on the SharePoint platform for conforming to the business needs. The PaaS model is suitable for the incorporation of flexible SharePoint application in SoftArc, since SharePoint is needed to be used primarily on remote locations. Problems encountered and the Solutions for incorporating SharePoint with PaaS model: There are many applications of hosting the SharePoint in PaaS model e.g. Azure like speed, simple deployment, and cost. But it also poses some unique challenges and problems. The question is related to the safety aspect of employing SQL content and SharePoint data in the cloud. The usage of SQL and Sharepoint in Azure are safe to store the secured content in the cloud as long as the system is configured in a proper manner (Microsoft, 2010).

Things Fall Apart An Analysis Essay Example For Students

Things Fall Apart: An Analysis Essay The culture of the Umuofia society before the colonial infiltration, may be hard to understand but we are forced by Achebe to realize it has traditions and customs that make it work. Although, looking at it from our Judaeo-Christian point of view we may be appalled by some of their practices. We also have to realize that they have strengths. Things Fall apart is the idea of balance and interdependence, earth and sky, individual and community, man and woman or different perspectives on the same situation. The central image of this balance is contained in the Ibo concept of chi,† which occurs throughout the novel. A persons â€Å"chi† is their destiny, his inner self, â€Å"you wouldn’t challenge your â€Å"chi† to a wrestling match,† as did Okonkwo when he assisted in the killing of Ikemefuna, whom he loved and who called him father. Okonkwo sins not only against the earth goddess, protector of family relations, but also against his inner most feelings or his â€Å"chi. † Any bad luck that occurs, people of this culture would say that you have a bad â€Å"chi. We will write a custom essay on Things Fall Apart: An Analysis specifically for you for only $16.38 $13.9/page Order now Okonkwo’s destiny is marked by bad luck, one reason may be that he is so riven by the fear of resembling his father that he struggles to repress part of his personality with predictably afflicted results. This was a society where a man was judged by his own achievement and not that of his fathers. Yams were the primary crop of Umuofia. A sign of manliness was if you could farm yams to feed your family. Okonkwo is respected because of his hard work. The complex patterns of Umuofia’s economic and social customs materialize throughout this novel as we see Okonkwo compelled to rid himself of any similarities that his father had. Unoka had no titles, was lazy and when he died was greatly in debt. Some may wonder how a society like the Ibo’s functioned, how they enforce its laws with no kings, no organized police force, and no standing army. Indeed this is something our â€Å"modern† culture could study. These things were accomplished through the functions of the masked spirits. The Egwugwu, represents the village’s highest spiritual and judicial authority. The masked spirits are believed to represent their ancestors. This supports the myth â€Å"The land of the living was not far removed from the domain of the ancestors. †

Psychology Vs. Psychiatry Essays - Medical Ethics, Free Essays

Psychology Vs. Psychiatry Essays - Medical Ethics, Free Essays Psychology Vs. Psychiatry it's not compleated yet... Both psychiatry and psychology come from the Greek word, Psyche, which means Soul. In modern society, the word, Psyche means mind, or use of the mind. Even though psychiatry requires a medical degree, and psychology does not, they are almost identical because they deal with behavior, mental health and counseling. Webster's dictionary describes behavior in the psychological sense as , The actions or reactions of persons or things in response to external or internal stimuli., or in a more simple form ; The way in which one behaves. In both fields, and working with patients with behavior issues, both psychiatrists, and psychologists, work in very similar ways. They both provide the same type of treatment, by using verbal communication, in trying to figure out the problem. They ask the same questions, give the same suggestions, and so on. The difference is, is that psychiatrist do a little more detailed research on the subject, and or patient. Mental Health is also a large role in both psychiatry, and psychology. The main difference, is that mental health can be more serious when dealing with a psychiatrist. Mental illness is described as , The psychological state of someone who has emotional or behavioral problems , serious enough to require medical intervention. Mental illness is a term used in psychiatry and psychology, in only severe cases. Bibliography none

Rights associated with land Essay Example | Topics and Well Written Essays - 2250 words

Rights associated with land - Essay Example Fishing rights in England and Scotland are private as opposed to public rights in USA, while water rights follow a riparian system in the UK and USA, except the western states where an appropriation system is used. Mineral Rights are provided to property owners who may have the right to allocate subsurface rights to other parties, but in England and Scotland the rights to precious and energy minerals rests with the Crown, while rights of ownership to other minerals may also rest with community bodies. Mineral Rights: In Scotland, land ownership is based on a feudal system whereby the owner or feuar was subjected to title conditions with reservations of mineral rights. Under the feudal system, previous owners of property known as feudal superiors, retained rights over the land even after it was sold, together with the right to enforce title conditions. (www.hmitchell.co.uk). This system was recently abolished under the Abolition of Feudal Tenure (Scotland) Act 2000, however despite the abolition of the system, a reservation of mineral rights in the feudal title still remains valid. As a result, it may restrict the mineral rights of owners of property. The Land Reform (Scotland) Act 2003 provides communities and crofts with the pre-emptive rights to acquire mineral rights, with the exception of oil, gas, coal, gold or silver.(www.lindsays.co.uk) The ownership of the rights to precious and energy minerals is vested in the Government. Throughout the U.K, mineral rights to gold and silver are owned by the Crown and the mines of these metals are known as mines royal.

Explain the role of government in economic matters for each Research Paper

Explain the role of government in economic matters for each subculture. Should the government be regulator or supporter Why - Research Paper Example The first of these which will be discussed is that of the individualistic approach. This can be defined as an approach to governance that places a high level of emphasis upon the predicate that the government should be restricted to allowing a high degree of private initiative. Although not strictly speaking a libertarian interpretation of the government’s responsibility to the system and vice versa, it is perhaps one of the more libertarian viewpoints of government’s role within society. Ultimately, within this context, government is seen to have a strictly utilitarian purpose ot maximize efficiency without allowing any firm of waste or bureaucracy to drain the productive energies that would otherwise result. Conversely, a traditionalistic political culture best describes a type of political culture that prizes family ties more than the other two which will be enumerated upon. Whereas the individualistic approach tries to minimize the role that government may play within society and or the community, the traditionalistic approach seeks to place a positive role that government can and should integrate with in regards to the community. Whereas other approaches place a great degree of emphasis on a particular determinant, the traditionalistic approach is no different in this respect as it places the highest degree of emphasis on seeking to engage the government in the task of maintaining the social order that is already in existence. In this way, this type of view is inherently conservative as it attempts to maintain the status quo via the utilization of governmental power. Similarly, the last form of political culture that will herein be enumerated upon is that of the moralistic political culture. As the name implies, this particular approach places a very high degree of importance on seeking to utilize the government as a â€Å"positive force† within

Time Value of Money SL4 Essay Example | Topics and Well Written Essays - 750 words

Time Value of Money SL4 - Essay Example I. Surge of economic challenges. In the recent past there has been an increase in the economic challenges that makes borrowing of capital a hard tussle. Most lending institutions have to put it hard since there is much of economic crunch. This makes health care to merge so as to increase the trust for borrowing. II. High interests that are charged. There is high interest charged in borrowing that makes many health care industries to merge so as to combine their resources. The fees that banks are charging for letters-of-credit associated with variable rate debt structures have doubled or even tripled in cost. IV. Lack of access to capital. Therefore lack of current capital accelerates consolidation in the industry through mergers, acquisitions, and closures. Hospitals making major improvements to their facility prior to the credit market disruptions will have a competitive advantage. In addition, hospitals with stronger credit profiles will have easier access to capital than hospitals with weaker credit profiles. (Giddy, 2014).Many hospitals are finding themselves unable to access capital at a reasonable cost while at the same time their existing variable rate capital structures are impaired due to credit downgrades with bond insurers, commercial banks, or interest rate swap

Biological Sciences Task Cells Biology Essay

Biological Sciences Task Cells Biology Essay Cells are grouped to form tissues, and each of them has specialised role. Our body develops from a cell known as the zygote that is the consequences of the fusion of the female ovum (egg cell) and the spermatozoon of the male (germ cell). Single cells are very tiny and cannot be seen with the naked eye. Cell types are distinguished by their dye (colouring) and by their shape and size. Cells consist of plasma membrane within which is number of organelles. Nucleus: it is a small electron particles composed of ribosomal RNA. The nucleus contains our bodys genetic substance that is in the form of large molecules of deoxyribonucleic acid (DNA). There are dozens of DNA molecules called chromosomes. The molecule of DNA is a series of nucleotide molecules known as proteins, and are connected by phosphate-sugar molecules. The nucleotide molecules contain one of the following materials known as bases: adenine (A), thiamine (T), guanine (G), cytosine (C). The bases are in set pattern; an in one chain is matching with T in the other and G with C. In this order of arrangement, each chain is complementary to the other. Every cell has the total match of genes needed to synthesise all the proteins, but majority of cells merely synthesise proteins that are suitable for their functions. It means enzymes can only be produced if the controlling gene is present, and when gene is missing, the linked enzyme is missing and there will be no chemical change. The RNA is responsible for the transfer of information from DNA to the cytoplasm where proteins are synthesised. Genetic information passes from DNA to RNA encouraging protein synthesis. (Anatomy and Physiology, 7th ed, 1990). Cell membrane: it is the most important organelle; it holds and keeps the cell intact. Cell membrane is moveable, and it moves along narrow passage. It is made up of phospholipids bilayers (two molecule layers), and has hydrophilic heads which are soluble in water and hydrophobic tails which are not soluble in water. The head has lipid molecules and a phosphate group (PO4) at the end. The apex and underneath layers of the membrane have stems that are facing each other. It also has proteins of which some are with carbohydrate. The cell membrane has 4 major functions, which are to maintain homeostasis, control the materials that can go in and out of the cell, and hold the cell together. (Cdli.ca, 2010) Cytoplasm: it is the basic substance that fills the cell, a fluid jelly-like substance that is eight percent (8%) water and typically plain in colour. Cytoplasm is also called cytosol (cell substance). It is found within the cell membrane and surrounds the nuclear cover and the cytoplasmic organelles. It is a substance that is made up of molecules and in which all the cells organelles are suspended and held as one by a fatty membrane. Cytoplasm can only be seen through an electron microscope, and it comes into view as a three dimensional lattice protein rich strands called microtrabecular lattice (MTL). It interconnects and holds other hard (solid) structure in the cytoplasm. The cytoplasm helps to move substances and it changes shape as it moves. (sln.fi.edu, 2010). Task 1.2 Explain the structure and function of the main cellular organelles. Nucleus: they are small electron particles that have ribosomal RNA. The RNA is responsible for the transfer of information from DNA to the cytoplasm where proteins are synthesised. Genetic information passes from DNA to RNA encouraging protein synthesis. (Anatomy and Physiology, 7th ed, 1990). Cell membrane: it is a sphere-shaped structure, and it is rich in ribosomal RNA and protein. It surrounds the contents of the cell and controls the flow of materials into and out of the cell. (HUMAN BODY, 2001). Mitochondria: it contains varieties of organelles, e.g, mitochondria and lysosomes. They are found in the cytoplasm and sometimes referred to as the power house of the cell. It produces a material known as adenosine triphosphate (ATP) which carries energy in all cells. (Anatomy and Physiology, 7th ed, 1990), (HUMAN BODY, 2001) Endoplasmic reticulum: it contains DNA and synthesises specialised proteins, e.g., muscle protein and steroid hormones, and it is linked with detoxification (process of removing a toxic substance) of some drugs. Endoplasmic reticulum is dotted with ribosomes, which consist of RNA. It helps to transport substances through the cell. (Anatomy and Physiology, 7th ed, 1990), (HUMAN BODY, 2001) Nucleolus: a tiny structure that is inside the nucleus. It permits the transportation of water-soluble molecules across the nucleus. Golgi complex: a heap of compressed sacs. It receive and process protein, the proteins are made to order and then released at the cell membrane. (HUMAN BODY, 2001) Lysosomes: potent enzymes; they mortify dangerous substances that is in the cell, and also dispose of other unwanted materials and weary organelles. (HUMAN BODY, 2001) Ribosome: they are tiny granular structure, and they play major role in the gathering of proteins. (HUMAN BODY, 2001) Nuclear pores: a membrane bound vesicle; plays a part in cellular digestive system. Task 1.3 Describe the role of nucleic acids in protein synthesis. DNA (deoxyribonucleic acid) is the genetic substance from which chromosomes in cells nucleus are formed, and it controls protein synthesis and inheritance (transmission of genetically controlled characteristics). Protein synthesis begins when the DNA coils provisionally relax at exact points. In the nucleus a doubled strand of DNA temporarily partly untwists. Transcription, which is the copying of the nucleus bases on one strand of DNA, begins to happen. Free bases match with those on DNA; adenine joins with thymine, guanine with cytosine, uracil substitutes thymine and joins with adenine. Forming a strand of messenger RNA. A completed strand of messenger RNA separates from the DNA, which twists back into place. The messenger RNA leaves the nucleus carrying the code for a protein into the cytoplasm. The messenger RNA with its series of codons (units of three nucleotides) for amino acids, attaches to a ribosome and translation starts. Translation, the sequencing of amino acids happens when free tRNA with its anticodon (units of three nucleotides) from the cytoplasm matches up and links to mRNA. When second tRNA joins, a peptide bond links the two amino acids at the ends of tRNA together, starting a peptide chain. The first tRNA separates leaving its amino acid behind. The ribosome moves along the mRNA reading the code. A third tRNA joins and the next amino acid is connected by another peptide bond. The synthesis continues until a stop or termination codon completes the process and the assembled polypeptide or protein is released. (HUMAN BODY, 2001). Task 2.1 Describe the structure and function of the cell membrane. Image of Cell membrane (lamp.tu, 2010). Cell membrane consists of a bilayer (two layers of molecules) of phospholipid (head and two tails) that is surrounded with mobile proteins. The phosphate head of phospholipid is hydrophilic, and the fatty acid tails are hydrophobic. The membrane structure depends on fatty acids molecules (lipids) in other to spread on the water surface. It is only one end of the lipid molecule that is attracted by water and the whole hydrocarbon tail is hydrophobic. The molecules form a monomolecular film on the water surface and scatter as very small droplets (drop of liquid). Fatty acids are able to support a double lipid bilayer when it is paired. Fatty acids in membranes are paired as phospholipids and glycolipids, joining saturated and unsaturated chains. Phospholipids are plentiful in membranes and glycerol, and are usually at the main structure. The fatty acid membrane is the storage place of the cell, it protects its content from dispersing casually, and it also permits control of the internal environment. Two lipid layers adhere to one another, in a double membrane, while it exposes water-soluble heads. Lipid molecules are free to glide in their layer. Common polar groups are ethanolamine, serine and choline. Sphingolipids are phospholipids with serine, their saturated hydrocarbon tails are usually longer and straighter than other membrane lipids, and it allows them cluster into rafts, which floats inside the membrane. Glycolipids are restricted to the external layer of the cell membrane. They are constructed like phospholipids, but the serine substitutes glycerol. Polar sugar chains might extend outside from the glycolipid molecules. Cholesterol straightens membranes by reducing fluidity of lipid. Rafts in particular, are rich in cholesterol. Tiny molecules that are soluble in oils, easily pass through the lipid bilayer, and they are O2 (oxygen) and CO2 (carbon dioxide). The lipid bilayers present a solid barrier to ions and other small molecules. The larger molecules do not have any chance of passing through lipid bilayers. The larger molecules are H+ (hydrogen), Na+ (sodium), K+ (potassium), Mg+ (magnesium), Ca+ (calcium), Cl+ (chlorine) and H2O (water). Membrane proteins has major role in determining what goes in and out of the cell. They detect and bind specified molecules, and then move them through the membrane barrier. About a half of the membrane has protein chains, the amount might be less in nerve cells because the membranes are rich in complex fatty acids. About a third of the cells genetic substance (DNA) codes for membrane proteins show their importance to the cell. Proteins are strings of amino acids, known as polypeptides. They fold into molecular sculptures (three dimensions), which they need in other to perform task that depend on their exact shapes and properties. Some proteins are at one side of the membrane while others go all the way through. Transmembrane protein channels transport specific molecules across the membrane. Majority of transmembrane protein have helical sections with other portions that are exposed on whichever side of the membrane. Helical section might come together to form tunnels. The helices cre ate a wave of contraction that moves ions from one side of the membrane to the other. Tiny ions, like potassium, calcium and sodium vigorously conduct across membranes by ATP-powered pumps. Some protein tunnels depend on gate to control the passive (inactive) flow of water and other polar molecules through the membrane bilayer. Protein chains might cross as beta sheet basket- like channels and allow larger molecules to pass. Protein chains might fasten in an electricity static state inside on leaflet, of the membrane, leaving the active domains to protrude (stick out) from the membrane. Long sugar chains (oligossacharides) attach to the external surface of the membrane proteins and glycolipids to form the glycocalyx. The glycocalyx declare the cells identity to the exterior. Membrane can overwhelm substances from the exterior. Endocytosis (membrane navigation) encloses large objects and drag them into the cell. Other viruses use their own membrane which can combine with the cell mem brane. (John Kyrk, 2010). Task 2.2 Explain the differences between osmosis, diffusion, active transport and bulk transport. Cells move water molecules, food particles, and other substances through the membranes. Things like water pass through easily, and others have to be moved through the channels. Solute; is a substance that dissolve in solvent to formulate solution, and solvent is a substance in which solute is dissolve to make a solution. Example is saltwater, in which salt is the solute, and water is the solvent. Diffusion is the mixing of two substances by random motion of molecules. Molecules move from an area of high concentration, to an area of low concentration. When the molecules spread out equally, diffusion stops, because there is no longer a concentration of gradient (steepness). Concentration gradient, is the difference between the concentration of molecule in one area and the concentration of molecule in an adjacent (beside) area. The system has reached its equilibrium, when the concentration of solute is the same throughout a system. Osmosis is the diffusion of water across a semipermeable (allows some types of things pass through) membrane. Water moves across membrane from a region of high concentration of water, to an area of low concentration of water. Facilitated diffusion is a movement of particles and diffusion across the cell membranes with the help of proteins in the membranes. Particles move down the concentration gradient going from high concentration to low concentration. Facilitated diffusion increases the rate of particles that cross the cell membrane. (biologymad.com, 2010) The process of diffusion, osmosis, and facilitated diffusion, does not need any energy to be used by the cell. The three processes are known as passive transport. The processes by which the cell uses energy to move particles across the membrane, is known as active transport. The cell movement of things from low concentration, to high concentration, is known as active transport, because it needs energy to do so. The cell uses active transport to keep the right balance of sodium and potassium ions in and out of the cell. This balance is vital for muscle contraction, nutrient absorption, and nerve pulse transmission. Bulk transport is for the movement large particles in and out of the cell. During bulk transport, large particles move across cell membrane packed in membrane-bound sacs. Bulk transport is of two types; exocytosis and endocytosis. Exocytosis is to move from inside the cell, to outside the cell. Wastes and cell products are packaged by the Golgi body in sacs known as Golgi vesicles. The vesicles combine with the cell membrane and materials are secreted outside the cell. Endocytosis are materials brought into the cell. Part of the cell membrane surrounds a particle that is outside the cell. The cell pinches a part of its outer membrane to form a new vesicle. When the vesicle is within the cell, it can combine with other organelles or release its contents into cytoplasm. There are two types of endocytosis; the pinocytosis and the phagocytosis. Pinocytosis is when a cell membrane surrounds a droplet of fluid and bring into the cell. Phagocytosis is when a cell engulfs (overwhelm) a solid substance and bring into the cell. Phagocytosis engulfs (surrounds and swallow) and destroys bacteria and other invaders of the body. Hypertonic solution; the concentration of solutes is higher than the concentration of solutes inside the cell, example is potatoes in salt water, water left the cells (diffuses out) and the potatoes became flexible. Hypotonic solution; solutes concentration is lower than the concentration of solutes inside the cell. Water diffuses into the cell, an example, is potatoes in distilled water, the water came into the cells, making the cell to swell and the potatoes becomes rigid Isotonic solution; the concentration of solutes equals the concentration of solutes within the cell. (biologymad.com, 2010) Task 2.3 Give examples of materials exchanged by different methods with a justification in each case. Diffusion: is a very slow process, materials exchanged, are gases oxygen and carbon dioxide. The lungs have high concentration of oxygen (O2) in the air sacs (alveoli), and a low concentration of oxygen in the blood of pulmonary capillaries. Carbon dioxide (CO2) has a low concentration in the alveoli, and a high concentration in the blood of the pulmonary capillaries. Oxygen diffuses from the air to the blood, and carbon dioxide diffuses from the blood to the air. (maexamhelp, 2010). Osmosis: it is where the cells lining the small intestine, absorb water. The exchanged material is salt. Cells take in salts and become more salty, and then water follows the salts into the cell. This process also takes place in kidneys because of its large demand of water. (maexamhelp, 2010) Active transport: nerves and muscle cells have sodium pump. Sodium ions (Na+) continually diffuse into the cell area of smaller concentration. Incoming sodium ions (Na+) are returned outside by the sodium pump. The nerve and muscle cells continually produce ATP to keep their sodium pump working. Another example is the assimilation of glucose and amino acids by the cells. The cells assimilate nutrients from digested food by the use of ATP. (maexamhelp, 2010). Filtration: blood pressure is formed by the pumping of the heart. Blood pressure force plasma and dissolve materials through the capillary membranes into the surrounding tissue spaces. This facilitates the creation of more tissue fluid and is also how cells get glucose, amino acids, and other nutrients. (Maexamhelp, 2010). Phagocytosis and Pinocytosis: cells that are stationary (immobile) receive small molecules that are attached to their membranes. The cells of the kidney tubules reabsorb small proteins by pinocytosis. (maexamhelp, 2010). Task 3.1 Explain the difference between mitosis and meiosis and explain when each occurs. Mitosis and Meiosis are both cells that have tricky division processes. Duplication of DNA occurs in both of them. The difference between mitosis and meiosis is well understood only if we know what the two cell division processes are, and they are as follows: Mitosis is a cell division process that involves eukaryotic cell dividing the chromosomes in two identical set of two daughter nuclei inside its cell nucleus. This is followed by cytokinesis that equally divides the nuclei, cytoplasm, organelles and cell membrane, into two daughter cells. Both mitosis and cytokinesis come together and form the mitotic (M) stage of the cell cycle. This series of events are divided into different stages known as prophase, prometaphase, metaphase, anaphase and telophase. Mitosis happens in different ways and in different species (types). Animals, for example, go through an open mitosis process which involves the breaking down of the nuclear envelope before the chromosomes separate, and the fungi and yeast go through a close mitosis process in which the chromosomes divide inside an intact cell (undamaged cell) nucleus. (buzzle.com, 2010) Meiosis is a reduction division process that halves the number of chromosomes per cell. The DNA in the original cell is duplicated during S-phase of the cell cycle, before it starts. Meiosis separates the identical chromosomes into four haploid (a single set of unpaired chromosomes) gametes. If gametes are produced, the cells will fuse (combine) during fertilisation to produce a new diploid cell (two matched chromosomes sets). Meiosis go through fertilisation in plants. The different stages of meiosis are meiosis l, prophase l, metaphase l, anaphase l, telophase l and ll. Meiosis is needed for sexual reproduction, it occurs in all eukaryotes that reproduce sexually. It does not occur in archaea because they reproduce asexually (no fusion of male and female sex cells gametes). (buzzle.com, 2010) The differences between mitosis and meiosis are as follows: No. Mitosis Meiosis 1 Takes place inside somatic cells. Takes place inside gamete cells. 2 A single division of the mother cell results in two daughter cells. Two divisions of the mother cell results in four meiotic haploid gametes. 3 A mitotic mother cell can either be haploid or diploid. A meiotic mother cell always diploid. 4 The number of chromosomes per nucleus remains the same after division. The meiotic products contain haploid (n) number of chromosomes in contrast to the (2n) number of chromosomes in mother cell. 5 It is preceded by a S-phase in which the amount of DNA is duplicated. In meiosis, only meiosis is preceded by an S-phase. 6 In mitosis, there is no pairing of homologous (similar) chromosomes. During prophase l, complete pairing of all homologous chromosomes take place. 7 There is no exchange of DNA between chromosomes. There is at least one DNA exchange per homologous pair of chromosomes. 8 The centromeres (region joining two parts of chromosome) split during anaphase. The centromeres do separate during anaphase ll, but not during anaphase l. 9 The genotype type of the daughter cells is identical to that of the mother cells. Meiotic products differ in their genotype from the mother cell. 10 After mitosis, each daughter cell has exactly the same DNA strands. After meiosis, each daughter cell has only half of DNA strands. (buzzle.com, 2010) Task 4.1 Explain the need for cellular specialisation in multi-cellular organism. Each human cell has different shape and size that depend on their specialised function. Speed of cells division varies; it is very fast mostly in epithelial cells, and continually replaces itself. However, it is slow or non-existent in a structural complex cell. Specialised cells are: Epithelial cells: they are from the skin, and cover most organ and line hollow cavities. Photoreceptor cell: is a type of light-sensitive cell that is found in the retina of the eye. They are activated by bright light and are responsible for colour perception (interpreting information from senses). (Integrated body, 2010) Red blood cell: a bag of oxygen-carrying haemoglobin molecules. Its biconcave shape allow for maximum oxygen absorption. (Integrated body, 2010) Adipose (fat) cell: its main cells, adipocytes, are bulky (large) and are jam-packed with droplets of lipids (fats), which store energy in case the diet cannot meet requirements. (Integrated body, 2010) Smooth muscle cell: this large, elongated (extended), spindle-shaped cells of smooth muscle are called muscle fibres. Its shape allow for contraction by means of sliding strands of protein within. (Integrated body, 2010) Nerve cell: every cell consist of configuration of short extensions known as dendrites, which is to receive nerve signals, and also has a long wire called axon, which is to send signals to other cells. (Integrated body, 2010) Sperm (egg) cell: every sperm has a head that transport the paternal (fatherly) set of genetic substances. It has a whip-like tail that propels it towards the egg. (Integrated body, 2010) Ovum (egg) cell: they are giant cells and contain the maternal (motherly) complement of genetic material, and energy resources for the first cell divisions that shape early embryo. (Integrated body, 2010) Task 4.2 Describe major tissue types and their functions. Tissues are groups of similar cells that carry out a common function. There are four groups of tissues in our body. They are epithelial, connective, muscle and nerve. Major tissue types and functions, are as follows: (Integrated body, 20100 Areola: a loose connective tissue, half-solid, allows food to pass through, inside has two other connective tissue types. They are yellow elastic and white fibrous with fibrocytes and mast cells that manufacture histamine a protective inflammation and heparin an anti-coagulant. They are mostly found in the body, connecting and supporting other tissues, such as between muscles and supporting blood vessels and nerves. They function as connection and support to other tissues. Adipose: these are fat cells that have fat globules. They are located between muscle fibres, under skin, around kidneys and at back of eyes. Their function is to protect, insulate and act as food reserve. Lymphoid: half (semi) solid tissue, some white fibres, lots of cells, of which majority are lymphocytes and reticular cells. They are found in lymph nodes, thymus gland, spleen, tonsils, appendix, walls, of large intestine and glands of small intestine. They function to form lymphatic system cells and blood cells. Lymphocytes and reticular cells function to control disease. Yellow elastic: this is elastic fibres, and very few cells. They are located in the lung tissue, bronchi and trachea, arteries, stomach, bladder and other stretchy or recoiling organs. They function as tissue enabling great expansion and recoil (shrink back). White fibrous: it is a strongly connective tissue, but not elastic. They are mostly closely packed bundles of collagen fibres. The fibres run in same direction. They form ligaments and periosteum (material making up bones) of bone. They form outer protection of organs, for example, protection of kidneys, brain and muscle fascia. Their function is connection and protection. Bone: it is the hardest structure of the body. It is compact outside and cancellous (not solid) inside. It has 25% water, 30% organic substance, and 45% inorganic salts. It is found in the skeleton. As compact, it functions as dense for strength, support and protection. And as cancellous, it functions as structure bearing and cellular development. Blood: is a fluid connective tissue, it has forty five percent cells, and fifty five percent plasma. It circulates inside cardio vascular system, and cells in cell production location. Its function is to transport food and oxygen to all cells and removal of waste from them. It also fights infection and clot blood. Cartilage: it is firm, tough, solid tissue. It has cells known as chondrocytes, and is of three types. Hyaline; is a blue and white smooth chondrocyte cells grouped together in a solid matrix (medium) and mainly resilient (hard-wearing). It covers parts of bone that form joints. The costal cartilages, parts of larynx, trachea and bronchi. Its role is connection and protection. Yellow elastic cartilage; these are fibres running (flowing) through a solid matrix. It contains fibrocytes and chondrocytes between multi-directional fibres. They are found in the pinna, the external cartilage of the ear, epiglottis, flap which prevents food and liquid entering trachea. It is flexible function. White fibrocartilage; white fibres packed with dense masses (lump). They are tough, a bit flexible, and contain chondrocytes. It is located in intervertebral discs, semi-lunar cartilages, and hip and shoulder sockets. Its function is to absorb shock. Task 4.3 Analyse body systems and assess the interdependence of their functions. The body systems are group of parts that are connected. They include organs and tissues that work together to perform particular functions. The system has separate processes inside the body, and each is dependent on the others. They work together as efficient functioning supportive system. Skeletal system: this is the skeleton, it a solid framework that is moveable and supportive of the body. It is where the rest of the body is built. The bone has a role in the other body systems. It is where white and red blood cells grow to build up a fatty tissue called red marrow. Its essential minerals, such as calcium, are stored in the bone, and to be released when there is shortage. Muscular system: it consist about half of the bodys bulkiness. It works with the skeleton, and its voluntary muscles allow the body to be exact in movements. The involuntary muscles, that comprise the heart muscle and the smooth muscle, are meant to provide the essential power (force) for the working (functioning) of the respiratory, cardiovascular, and the digestive systems. Nervous system: this is the brain, and it is the site of both consciousness and creativity. The brain, through the nerves of the spinal cord and the system of nerves that branch to all other parts of the body, controls all body movement. It also communicates with the endocrine glands and influences the functions of the other body system. Endocrine system: this is the hormones and chemicals that act (take action) on specified tissues, and then affect the bodys interior balance. It is secreted by endocrine glands and other organs. It flows in the blood and other body fluids, and also starts the changes that take place during puberty. Cardiovascular system: its most basic function is pumping blood around the body. It supplies all organs and tissues with oxygenated nutrient blood. It can get use to changes in demand quickly. Waste products are removed during blood circulation. Lymphatic system: it provides very important protection from infectious disease and also prevents malfunctioning of the internal tissues. (JK, 2010) Respiratory system: it is made up of the nose (nasal cavities), which filter inward bound air. Also consists of the pharynx, the larynx, the trachea, the lungs and the air sacs. It is the site of oxygen and carbon dioxide exchange. Digestive system: the work of the digestive system is to reduce large and complex substances to water soluble so that the cell can use them. The process is both physical and chemical. The digestive system is of two parts; the alimentary canal (mouth, anus, throat, oesophagus, stomach), and the small and large intestines. Urinary system: its excretory organs get rid of liquid wastes. The nephrons filter the blood and remove unwanted substances as wastes, and return necessary substances and fluids to the blood. The expelling of urine waste is started by the voluntary relaxing of the sphincter. In the female, the urethra empties in the area between the clitoris and the vagina opening. And in the male, urethra, which is about twenty centimetres long, runs through the penis. Male reproductive system: it is where sperm are produced and contained in the scrotum. The sperm and its fluid are known as semen. The semen is ejaculated into the urethra and penis, and from there, into the females vagina. Female reproductive system: it is about seven to ten centimetres long, receives the sperm from the male. The sperm must reach the uterus. The cilia assist the sperm as they swim up towards the egg. A fertilised egg is formed if a sperm enters the egg, and it is called zygote. The zygote passes through the uterus and becomes attached to its lining. The cells increases and develop into fetus (unborn offspring). (Human Anatomy, 1982). Homeostasis: all of the human bodys systems work together to maintain equilibrium, two of the body systems are very important for the maintenance of homeostasis. They are the nervous and endocrine systems.

Organ Donation :: essays papers

Organ Donation In March of 1999, I was given a gift from a person I never knew; a person I’ll never get to know. This gift cost the person who gave it to me, no money, but it was the most valuable gift I’ll ever receive. The gift was a piece of life from another person. At the age of twenty-four, I broke my hip. After three unsuccessful surgical attempts to heal it, my doctors performed a total hip replacement. The top four inches of my femur were sawed off, and the inside of my bone was hollowed out. A steel rod, nine inches long, was â€Å"pressed fit† into my bone. I was on crutches for over a year, but I really believed I would be able to walk on my own again. Less than one year after the surgery, I was back on crutches and in terrible pain. I had developed stress fractures in several places along my femur. For nearly one year I walked only when it was necessary and ate painkillers as though they were candy. Finally, my doctors decided to try something new. On March 9, 1999, my doctors took a rib bone, donated from a cadaver, split it in half, and wired it around my broken femur. Less than two months later, I was off crutches and walking normally for the first time in almost five years. I could actually enjoy life. I was lucky. I wasn’t going to die if I had no donor, donated bone is easier to acquire that a heart, lung or kidney. Other people are not as lucky. Patients waiting for one of those life-sustaining organs must rely on the generosity of others, and the misfortune of that generous person. Someone must die, in order for that person to live. No one likes to talk about death, but let’s face it, we all die. Dying is a part of life. Many people don’t talk about organ donation because it involves talking about death. But, what if, from our death, we could give another person a chance to live, or merely improve the quality of his or her life? As of September 1999, over 65,000 people wait, with their name on a list, for a life saving organ. Only a fraction of those will live long enough to receive that organ.
