Define social contract theory. What does it attempt to explain? Solution According to social contract theory - “morality consists in the set of rules governing behavior, that rational people would accept, on the condition that others accept them as well.” (Rachels, p. 145) We are already familiar with the concept of contracts like marriage, citizenship and employment. Put simply a contract is a sort of agreements betwween two parties. if one party voilates theterms of the agreement, the contract is no longer valid. Societies are controlled by governments. This is the starting point of discussing social contract theory. Put simply this theory attemps to explain the fact that people benefit from living together in countries, kindom or under any other governmental jurisdiction. Living in societies hoever requires rules and laws. Societies are the result of compromises and social contracts provide framework for how people and governments are to interact. Individuals who stay together may gain protection from the other social elements that might try to harm them. In return they must give up certain freedoms like ability to commit crimes without being punished. They should contribte to making societies stable, healthy and happy. The idea of the social contract has a long history leading as far as the ages of mesopotanians. however it was not until the enlightment of 17th and 18th century that social contract theory gained widespread attention. The enlightment was a time when intellectuals began to question established views relating to religion, science, economics and government. Social contract theory challenged both the moral and social elements of power..

Briefly explain why heating water close to boiling in a test tube would dramatically increase the rate of distribtution of dissolved particles, like KMno4, so that they distribute within the entire tube within several seconds? Please be specific in explanation. For animal physiology class. Solution It is due to the mechanism of convection. KMnO4 will distribute easily when water in the test tube is boiled, because heat transfer in a liquid occurs by the liquid movement itself. The liquid which is present at the bottom will get hot first and this will rise to the surface and the liquid from top reach the bottom, like this the liquid will move in a loop pattern (phenomenon called as convection) and this will allow the uniform distribution of water soluble particles present in that water..

A) Explain five (5) challenges amphibians faced when colonizing land and how they solved them. B) Explain the improvements reptiles evolved from the amphibian solutions (the five (5) listed in the question above) to adapt to terrestrial environment Solution a) The terrestrial realm of land and air offers many challenges to organisms adapted to aquatic life: Gravity:aquatic life is buoyed by water.Air is not so buoyant! So terrestrial animals have to have some sort of supporting tissue.Endoskeleton of bone and lobe fins modified to limbs.Also changes in skeleton for land hunting - Shoulder free from skull to give head more flexibility and arm greater lateral movement Descication: air is drier than water,so terrestrial organisms need some form of skin or coat to keep all their precious bodily fluids from leaking out.Fish scales don\'t protect the body much against desiccation. Besides Amphibians lost those scales early in their evolution.Amphibians never really solved the skin-permeability problem.They are restricted today to moist habitats. Respiration: aquatic organisms exchange oxygen and carbon dioxide dissolved in water.In air,these substances are gases,so new structures are needed to breath.Fish breathe the oxygen dissolved in water through their gills.Out of the water,however,they are unable to survive for more than a few minutes.In order to live on dry land,they need to acquire a pulmonary system.They developed lungs inside body and stronger rib cage. Reproduction:aquatic organisms often release their eggs,sperm,etc.,directly into the water.This approach is much less effective in air,so other solutions evolve.But there is no special adaptation,return to water to mate. Locomotion:aquatic animals can swim,scuttle,squidge,orotherwise move through the water.These motions have to be modified in the terrestrial realm. Senses:light,sound,and smell transmit differently in water than in air,and some senses don\'t work in air at all.Terrestrial animals have to evolve new adaptations to deal with these differences.Lateral line which senses vibrations under water becomes lost and an operculum overlaying the lower jaw is used to sense vibrations in air. Excretion:Due to the abundant water in their environment,marine creatures can immediately filter and expel their bodies waste products,particularly ammonia.On land,water must be used at minimum levels.For that reason these living things have kidneys,in which ammonia is filtered out as urea and stored in the bladder,and the minimum amount of water is used when it is expelled.In addition,there is a need for new systems that enable the kidneys to function.Amphibians ability to conserve body water is rudimentary.Considerable water is lost by evaporation through their skin.Most species excrete a copious and diluteurine because a large volume of water is needed to flush out toxic excretory products through their kidney tubules. b)Amniotic egg:Amphibians never succeeded in becoming fully terrestrial because.

a. Explain how chronic bleeding leads to iron deficiency anemia. b. Explain the signs of anemia that indicate compensation for hypoxia is occurring. c. Explain how the destruction of acid- producing cells in the stomach can lead to iron deficiency anemia. Solution a. Iron-deficiency anemia is anemia caused by a lack of iron.It is the most common type of anemia. Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. Blood contains iron within red blood cells, so blood loss leads to a loss of iron. There are several common causes of blood loss: Women with menorrhagia (heavy menstrual periods) are at risk of iron-deficiency anemia because they are at higher-than-normal risk of losing a larger amount blood during menstruation than is replaced in their diet. Slow, chronic blood loss within the body — such as from a peptic ulcer, angiodysplasia, a colon polyp or gastrointestinal cancer, excessively heavy periods — can cause iron-deficiency anemia. Gastrointestinal bleeding can result from regular use of some groups of medication, such as NSAIDs (e.g. aspirin), anticoagulants such as clopidogrel and warfarin, although these are required in some patients, especially those with states causing thrombophilia. b. Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body. Hemoglobin plays a substantial role in carrying oxygen throughout the body, and when it is deficient, anemia can result, causing \'anaemic hypoxia\' if tissue perfusion is decreased. Iron deficiency is the most common cause of anemia. As iron is used in the synthesis of hemoglobin, less hemoglobin will be synthesised when there is less iron, due to insufficient intake, or poor absorption. Anemia is typically a chronic process that is compensated over time by increased levels of red blood cells via upregulated erythropoetin. A chronic hypoxic state can result from a poorly compensated anaemia. The signs that indicate compensation of hypoxia are fatigue, weakness, dizziness, headache, low body temperature, pale skin, irregular heartbeat etc..

8. Identify the causes and symptoms of endocarditis, myocarditis, and pericarditis Solution 1.Endocarditis: Causes: Endocarditis is caused due to inflammation of endocardium layer of heart. caused due to infection in the valves of the heart and the inner lining of heart.The main cause is infection through bacteria and less extent fungus and other microorganisms that enter the bloodstream and attach to the heart valves.Rheumatic fever is often the cause of endocarditis. Symptoms: Include fever,sweating, fatigue,pain in joints and muscles,breathing problems,change in heart sounds,weight loss,enlargement of spleen,appearance of blood in uine,appearance of Osler\'s nodes in which red spots appear under skin of fingers and petechiae in legs. Myocarditis: Causes:Caused due to inflammation of the muscles of heart known as myocardium.Chaga\'s disease is the main cause behind myocarditis.It may be caused by viral ,protozoan ,fungal,bacterial or parasitic infection.Autoimmune diseases such as rheumatoid arthiritis may also cause myocarditis.Alcohol, drugs such as anthracyclines also cause myocarditis. Symptoms:Pain in the chest,abnormal heart beats,high fever ,congestion in the heart,joint pain, fatigue ,diarrhea are some of the symptoms. Pericarditis: Causes:Caused due to inflammation of pericardium layer of the heart due to infection by virus, bacteria or fungus. Viruses such as coxsackievirus, herpesvirus, mumps virus, and HIV , bacteria such as pneumococcus and anaerobic bacteria, fungus such as Aspergillus and Candida are the causative agents.Apart from this cancer, autoimmune diseases etc aldo cause pericarditis. Symptoms:Sudden chest pain,shoulders,neck and back pain,fever,palpitations,fatigue,breathing problems, and heart attack are some of the symptoms..

Will you explain chemical bonds? Solution A chemical bond can be technically defined as an association between two or more elements by the means of either sharing of electrons, donation/acceptance of electrons, formation of hydrogen bonds or weak interactions. Chemical bonds are formed to give rise to a compound which is chemically stable. A chemical bond can be of following types: Thus, this information suggests that there are multiple types of chemical bonds which together help in formation and maintenance of virtually all the molecules including biomolecules in living and non-living systems..

What specific balance sheet account provides the link between the balance sheet and the income statement? Thoroughly describe how this linkage works. Solution The Retained earnings account in the balance sheet provides the link to the income statement. Retained earnings are the residual earnings left over after distributing the cash dividends to the stock holders. Closing retained earnings= Opening retained earnings + Net income - Cash dividends. Net income is arrived from the income statement Cash dividends are arrived at by the Board of directors Opening retained earnings are the earnings carried forward from the previous years. Closing retained earnings is added to the stockholders equity account and reflected in the balance sheet. The carrying of the net income to the balance sheet ensures there is uniform distribution of accounts from the income statement to the balance sheet and also ensures balance of accounts.
