You are designing different liposomes for drug delivery through the blood stream and for skin application as a topical lotion. Describe your selection of lipids for each application that would ensure that liposomes remain in a semi-fluid state between liquid-ordered and liquid-disordered states.

(i) What role does the sensory qualities of food have in determining body weight regulation (60%), (ii) outline key differences in the sensory perception of nutrients between lean and obese individuals (20%), consider additional clinical situations where sensory perception may be lost and what effects this might have on metabolism (20%).

a) in mark and recapture method, how does the variation in values of N (estimated size) change as a function of the size of the recapture sample (when we increase the recapture sample)?

b) what is the general effect of recapture effort on the variability associated with population size estimates in mark-recapture studies?

Ions of iodine react with enzyme amylase and used as quantative test for measuring quantity of amylase. However, ions of iodine react with enzyme amylopectin very slightly. Why.
