Which of the following statements true about Cyanobacteria? Cyanobacteria ... are a diverse, polyphyletic group of bacteria. use chlorophyll a and release oxygen during photosynthesis. are the only group of autotrophic bacteria? can reproduce sexually. are obligate aerobes. Solution Ans. B and E Cyanobacteria also known as blue green algae as it is blue green in color present in aquatic environment and produce its own food using chlorophyll a and release oxygen as a byproduct in splitting of water. Other bacteria use H2S and hence doesn\'t release oxygen and also doesnot possess chlorophyll a. Cyanobacteria are obligate parasites and prefer dilute carbon source.

What does IPO underpricing refer to? When in recent decades has it been most severe? What are some reasons that underwriters might want to underprice their IPOs? On the other hand, what might be some problems with this approach? Solution IPO refers to Initial Public Offer and underpricing refers to Pricing of shares lower than the market value. Hence, IPO Underpricing refers to the listing of the initial issue of the company at the rate below the market value of the share. Underwriters does so to make the shares feasible for every investor to invest in. Not every share is approachable to the small investors. So the motive of the IPO Underpricing is to make the issue approachable financially to small and big investors both.Thereby, knocking the opportunities for potential small investors and grabing small pockets of many investors. The problem can definitely be that the big investors doesnot look these IPO\'s and show less interest in investing them and hence the issuer will not be able to collect fund in one go..

When summing forces in the x direction why does Force of Ax be included? Wouldn\'t Ax not be included because it is considered an internal force? Solution Ax is an external force that\'s why it is included in calculating the net force in a direction .Internal forces have no role in FBD of a body as the are cancelled on its on by action reaction. Ax is included in the net force in the X-direction because it is one of the force that is applied externally and bring a change to the system..

What role does ethics play in leadership? Do you believe that some people abuse it? Why or why not? Provide examples. Solution his is extremely interesting territory. Organisations and people within organisations rarely if ever demonstrate a homogeneous mix of ethical values, but they do have to function. Ask the question. How will the Iraq even create a temporary framework to govern given that it seeks to balance such disparate issues? History tells us that we compromise because the alternatives are often far worse. Pragmatism becomes the order of the day and I think that this is a pattern that is repeated in corporations. Organisations function according to their perception of how they need to respond to the power of the circumstances around them. There is a behavioural bottom line for organisations which should not be crossed (ethical considerations embodied in the law) but, there is a vast array of other ethical issues that may or may not be taken on board. They are generally only taken on board when it is perceived that the short term self interest of the company matches the ethical value. Organisations then present different images to their stakeholders to maximise the warm glow that they project. Profit to the shareholders. Respect me vibes to the institutions. We work for our workforce vibes to employees and their supporters. All these images conflict and one of the key roles of leadership (setting the agenda) is to ensure that this conflict is managed and the business machine does not slow down. Those leaders who have gone through the processes of: 1. Learning to lead and manage themselves. 2. Developing a clear understanding their values and goals. 3. Learning to lead and motivate others. 4. Learning how to apply leadership strategically. will manage without falling off the horse. It is unlikely however, that they will lead on ethics even if their standpoint is ahead of their company\'s minimal position. They are more likely to gratefully respond to what the social consensus seeks to make imperative..

What is Simmonds’ disease aka pituitary cachexia? Describe the features of the disease Solution Answer: Simmonds\' disease or pitutary cachexia is a disease caused by the destruction of the anterior lobe of the pitutary gland due to any cause, like post partum necrosis of the pitutary gland, trauma like bullet injuries or fractures at the base of the skull, morbidities like tuberculosis or syphilis, tumors of the pitutary and supra cellar cysts are some of the main caises of Simmonds\' disease. Features are: 1. as post-partum necrosis is one of the major causes of simonds\' disease, it is most common betweeb ages of 20- 45 years. it is more common in women than men. 2. earliest manifestation of the disease are evident soon after few days from puerperium. 3. Failure of lactation or rather engorgement of the breasts is noticed. 4. Patients are of average nutrition and have a pale, dry, rather sallow skin suggesting a degree of anemia more severe than what the hematological examinations reveal with a possible subthyroid condition. 5. Progeria is unusual 6. Head hair is normal in size and texture. 7. eyebrows are thin. 8. disturbance in menstruation with amennorhia or scanty and irregular periods. 9.

The steps in the electron transport chain in anaerobic respiring bacteria, and the fermentation pathway in fermenting bacteria both: Produce ATP. Produce Ethanol. Produce NADH. Generate a proton gradient. Regenerate NAD^+. Solution Answer: Produce ATP Anaerobic respiration is a process without oxygen and uses a respiratory electron transport chain but does not use oxygen as the electron acceptors and generates only two molecules of ATP. It also produces ethanol or lactic acid Fermentation (alcholic and lactic acid fermentation) occurs in bacteria that convert sugars into acids, alcohol, or gases. In the presence of O2, NADH and Pyruvate are used to generate the ATP.

Sally\'s brother is color-blinded. Her husband is normal. What is the chance for her son to be color-blinded? Solution Answer:one in two (50%) chance Color blindness is X linked recessive inheritance. two copies of a disease allele on the X chromosome are required for an individual with two X chromosomes (a female) to be affected with an X-linked recessive disease. Affected males transmit the disease allele to all of their daughters, who are then carriers, but to none of their sons. Therefore Sally’s brother must have got the disease X chromosome from her mom. Sally must be carrier. For a carrier female, with each pregnancy there is a one in two (50%) chance her sons will inherit the disease allele..

Let P represent the set of all polynomials with integer coefficients. Prove that P is countable. 4. Let I 0,1] and J 0.21 losed intervals of the real line). Show that III J lJl. Solution A surjective function is called a surjection. Example: f(x)=x (2). If X is a countable set, then we refer to an onto function f : N X as an enumeration of X, and write X = {xn : n N}, where xn = f(n). (3). P(n) = {n is an element of the integers| axn + bxn-1 + ... where a,b... are integers.} P(1) = {ax1}. There is one element in this set therefore this set is countable.

Show P(K+1) is true i.e. that P(k+1) = {k+1 is an element of the integers| ax(k+1) + bxk + cx(k-1) ... where a,b,c... are integers.} is a countable set. By our assumptpn we are trying to show that {k+1 is an element of integers | ax(k+1) + a countable set) is a countable set. (4) Two sets I, J have equal cardinality, written I J , if there is a one-to-one, onto map f : I J A surjective function is called a surjection. Example:f(x)=x (2).
