1. Comment “Fatty acids are storage fuels”. The weight of a person ABC is 65 kg. About 11.5 kg of his weight is due to the fat deposits in the body. He went for a hunger strike. Can you explain how long he can survive? i. without water and food? ii. without food but with water?

1. Without food and water
2. With water and without food
Carbonic anhydrase is strongly inhibited by the drug acetazolamide, which is used as a diuretic. Carbonic anhydrase plays a significant role in the secretary processes because it participates in regulating the pH and bicarbonate of body fluids. The experimental curve of initial reaction velocity versus [S] for the carbonic anhydrase is shown below. When the experiment is repeated in the presence of acetazolamide, the lower curve is obtained. Determine the nature of inhibition. Explain with reason.
. A man ate food with low protein, high carbohydrate produces 6.2 g urea per day. The same man excreted 26.2 g urea per day after three days. Explain the data with logical reasoning.

1. After a severe ecological disturbance, explain the importance and role of pioneer plants. (2 marks)
Pioneer plants are important because they replace the species that were lost during a forest fire. Its also the first stage of succession.
is this right? let me know thanks
1. Explain the important of a keystone species in a community. (2 marks)
keystone species are important in a community because keystones determine the communities structure. If it is removed, community interactions are significantly altered, and the other species change dramatically.

a) Assume the population of Bacteria B completely dies off. Bacteria A are now transferred to an open environment where they have lots of room for growth and a continual supply of food. Over the course of three days, the population of bacteria steadily increases as follows:
Day 1: 1500 bacteria
Day 2: 3000 bacteria
Day 3: 7000 bacteria
Day 4: 13,000 bacteria
Is this population of bacteria r-selected or k-selected? Explain how you arrived at your answer. Hint: Review your definitions of “r” and “k.” (2 marks)
This bacteria is k selected, because k-selected species mature slowly, they have a longer life span and they provide more parental care so that when their offspring matures it can survive in any environment. Correct?
