Q1. We estimate the size of a population of small mice in a particular field by the mark-response method. Our estimate is 350. Later, we learn from experiments on the behaviour of these mice that they can locate a baited trap faster if they have already been rewarded with food by visiting that trap once before. Does this mean that our original estimate of 350 individuals was too low or too high? Give details the answer in terms of the principles that underline the mark recapture method.
Q2. Lack of iron in photic zone of the open ocean restricts the size of plankton populations. Iron is what kind of factor for marine plankton?
We are told that every surface we touch is teeming with bacterial cells, and bacteria are found in the pools we swim in, water we wash with, and on the hands of friends. Why don't we always have problems with bacterial infections all over our bodies.
Both endocrine and nervous system are major regulating systems of the body; however, the nervous system has been compared to any post mail delivery system and the endocrine system to the pony express. In brief explain this comparison.
What do you think is the most probable mechanism of browning? If a patient's resting cardiac output is 5.6 l/min and on a stress test she elevated her heart rate to the highest of 176 beats/min with a stroke volume of 115 ml/beat, what is her cardiac..

If the ATP synthase molecules were randomly orientated so that about half faced the outside of the vesicle and half faced the inside, would you expect ATP to be synthesized.
