What are two examples of division of labor in bacterial colonies? Solution Ans. The division of labour is one feature of the most sophisticated biological systems, including genomes, multicellular organisms and societies, which took millions of years to evolve. Mutants emerge within bacterial colonies and work with the parent strain to gain new territory. Example - the two strains self-organize in space:- one provides a wetting polymer at the colony edge, whereas the other sits behind and pushes them both along..

For each of the lymphatic and immune systems explain how one (1) component of each of the organ systems (a cell, tissue, or organ) contributes to the function of either detecting or fighting off an infection. (3 marks each; 6 marks total) Solution Lymphatic system is a closed circulatory system that consists of lymph capillaries, lymph vessels, and lymph nodes. The lymph present in capillaries flows into lymphatic vessels, which are presented deep or superficial. This lymphatic system is mainly involved in the production of \"active and passive immunity\" (components of immune system) against the foreign pathogens entered into the host system. Lymphatic system is going to produce lymphocytes to defend these pathogens by opsonization & finally eliminate them out of the host body. Lymph node is a lymphatic organ where the cleansing of the lymph and activation of T-cells and B-cells will occur. Parenchyma of the lymph node is divided into cortex and medulla. Cortex is the outer part, which is C-shaped and encircles the four-fifth of organ. Cortex contains conical or ovoid shaped lymphatic nodules. Medulla is the inner part, which extends to the surface of hilum. Medullary cords are present in the medulla. This medullary cord consists of lymphocytes, macrophages, plasma cells, reticular fibres and reticular cells. Both the cortex and medulla consists of lymph-filled sinuses, which are continuous with subcapsular sinus. Lymphatic system is a closed circulatory system that consists of lymph capillaries, lymph vessels, and lymph nodes. The lymph present in capillaries flows into lymphatic vessels, which are presented deep or superficial. These lymph vessels combine to form lymphatic trunks that empty into the large collecting vessels of lymphatic system called “thoracic duct and right lymphatic duct.” The lymphoid tissue is mostly composed of a reticular connective tissue (a type of loose connective tissue). The fibres of the reticular network contain macrophages. A number of lymphocytes from the postcapillary venule walls occupy this network and leave to the body again. This ensures the lymphocytes to identify the infected sites at a faster rate. The components of lymphoid tissue include the following. 1). Lymphoid cells: Lymphocytes are produced (lymphopoiesis) by primary lymphoid tissues or organs, which include red bone marrow and thymus gland. These are the main cells of immune system; they mature into two types of immunocompetent cells known as T-lymphocytes and B-lymphocytes contributes to the function of either detecting or fighting off an infection. a). T-lymphocytes: The thymus gland produces “T lymphocytes” (T for thymus) from the lymphoid stem cells under the influence of thymus hormones. The matured T cells (differentiated) are mainly involved in the process of cell-mediated immunity. b). B-lymphocytes: B- Lymphocytes are produced from the red bone marrow and are mainly involved in providing antibody mediated immunity. When these cells .

Describe Milgram’s controversial research on obedience, and discuss its implications for understanding our susceptibility to social influence. ****PSYCHOLOGY Solution Stanley milgram is a famous psychologist at Yale University who conducted experiments focusing on the conflict between obedience to authority and the personal conscience. This test tests how much pain would be bore by an ordi ary man by the orders. The extreme willingness of man to go to almost any length of command of an authority constitutes the chief finding of the study. Milk Ram computer that ordinary people follow orders given by Authoritiedr it is even to the extent of killing an innocent human being obedience to authority is ingrained in us all from the way we are brought up. He explains the behaviour of his participants by suggesting that they have two states of behaviour. The first one is autonomous state in which people direct their own actions and the second one is a genetic state in which people allow others to direct their actions. In the second state the people will believe that authority it will take responsibility for the results of the reactions.

Can two people with lobed ears have a child with attracted ears if they each had a parent with attracted ears? Solution The recessive allele in a person\'s phenotype is the one that is unexpressed. The phenotype is the physical makeup of a person that can be seen. Some traits have more than two alleles to them. During reproduction, there is a crossing over of chromosomes between the mother and father. For many phenotypes, the alleles from each parent will make up the chromosomes of the child. In some situations, if the two parents each have one recessive allele for a certain trait, their child can end up displaying the recessive phenotype. This means that both of them can have lobed ears but their child could have attached earlobes..

Can Bacteria carry out phagocytosis? Explain: Solution Bacteria cannot carry out phagocytosis, all prokaryotes are very very small and have cell walls. They have many methods of transport across the cell wall and cell membrane, but not \"bulk transport\" through any kind of endocytosis. When eukaryotes do this, they bring in the outside material into a vesicle which then merges with a lysosome. For example, if bacteria were to bring in outside material, they would need a way to release it or merge it with another vesicle, but prokaryotes don\'t have any organelles or vesicles. Having said all that, there are weird exceptions to almost everything and hence there can be a possiblity of phagocytosis documentation in prokaryotes at some point in the future..

About half of the paid lobbyists in Washington are former government staff members or former members of Congress. Why would interest groups employ such people? Why might some reformers want to limit the ability of interest groups to employ them? On what basis might an interest group argue that such limits are unconstitutional? In 75 to 150 words only. Solution Interest groups may be the authentic voice of weaker or oppressed groups in society that do not have the means or standing to organize as interest groups. Social movements are often the first expression of latent discontent with the existing system. A former member of Congress can offer invaluable assistance when an interest group seeks to affect lawmaking. Without them these groups would have less influence on administrative rulemaking and on legislation. Some reformers have argued that interest groups gain improper influence by hiring former government employees. Hence they say, such hiring should not merely be restricted but should be banned altogether. If this were to happen, interest groups that frequently hire former employees should be less effective. *****.

Compare the development of two imperial powers. What factors inspired these nations to develop empires? How did the powers first gain control over their imperial territories? How did they administer their territories? What role did the local populations play in the imperial relationship? Solution Britain and Japan are the two great industrial imperial forces of the modern world. Britain dominated the Western, European-dominated world and Japan of the Eastern, non-European, and to many eyes, the hope of the third world. They many things in common, groups of islands, more civilized and powerful, and defence services. Britain was the first industrial nation at a time when nobody knew what an industrial revolution was. It was slowly evolving without even aware what modernization would be. But Japan was fast to realize what the gains and danger of industrialization were and adopted it self-consciously with revolutionary speed. Japan transformed itself from a feudal society to the most efficient industrial and egalitarian aristocracies in the world. The fact is that the then leaders of Meiji Restoration were prepared to abolish feudalism, establish equality, and contribute to the survival and development of the country. The British educational road was very much slower in relation to Japanese education system which very much advanced. British managers never went to university unlike their Japanese counterparts who went to a variety of technical colleges. Japan believes in full-time higher education and has far larger number of universities and colleges. The key to the British industrial revolution was social ambition and that of Japan was to expel the barbarians and restore independence. In Britain there is a gentleman’s agreement, more gentlemanly tradition. Welfare, leisure, and a civilized social life are more important acquisitions of the British, and economic growth came second. Britain and Japan took two different routes because they were two different societies with different social structures and ideals. *****.

What it means to say that u and v are linearly DEPENDENT is that there is a number B 0 so that u Bv (u depends on v). Let T be a linear transformation. Show that if u and v are linearly dependent, then T(u) and T(v) are also linearly dependent Solution If u and v are linearly dependent means there exist some b so that u=bv T(u)=T(bv)=bT(v) ie T(u)=bT(v) Hence, T(u) and T(v) are linearly dependent.

What is the function of the pleura? How do differences in alveolar and atmospheric pressure contribute to ventilation? What is a pnemothorax? What is the mechanism contributing to the pathology? Solution Pleura is the outer covering on the lungs.These are two membranous strcutures called visceral pleura(inner) and parietal pleura(outer) that cover the lungs. The function of pleura is to enclose the space called pleural space that contains pleural fluid which helps in easy and frictionless movement of lungs during expansion and contraction inside the ribcage. Alveloar pressure is the pressure of air inside the lungs. When inspiration starts, lungs expand in the thoracic cavity. This expansion increases the volume of the lungs that causes expansion of air too inside the lungs. The expanded air has low pressure , so the pressure of air decreases slighlty in the lungs whereas the pressure outside(atmospheric pressure) is higher. Air moves from high pressure to low pressure so it starts moving from atmosphere to respiratory pathway to alveoli. During Expiration, Lungs contract, volume inside the lungs decreases, alveolar pressure increases. This pressure difference between lungs and atmposhere is sufficient to cause outward movement of air. Pneumothorax is the condition in which the air collects outside the lungs in the chest/thoracic cavity.This condition can arise due to a disease, injury to lung that causes damage to pleura or even sometimes in absence of anysuch condition (Spontaneous pneumothorax). Pathophysiology of pneumothorax is not very clearly known. It has been noticed during this condition the emphysema like changes occur iin alveoli, necrosis of alveolar tissue,formation of air filled lesions under the pleural surface.

What is anchorage dependence and how does is work in normal cells and what happens if a normal cell is not \"anchored\"? Solution Anchorage dependence is required for normal cells for their attachment to the surface and for growth and division. Cells proliferate only when attached to the surface. The cells are adhered to other cells, extracellular matrix and to culture plate. If the anchorage dependent cell loses the anchorage property then the cell will die. The cellls are anchored by receptors, tight junctions. It a normal cell is not anchored then it will not survive and is unable to grow and multiply..
