In dark/dim conditions the human pupil dilates (diameter increases) to allow more light in.In bright conditions the pupil constricts (diameter decreases) and less light enters the eye.This is through a co...

A= 0.6 a= 0.4 p+q=1 where p=A and q=a p²+2pq+q²=1where AA=P² Thus AA frequency in the population = 0.6²= 0.36Aa=2pq Aa frequency in the population = 2(0.4 X 0.6...

Diuretics can reduce the amount of Na+ that is reabsorbed by the nephron (leads to excretion of more salt and water in the urine)
The reabsorption of Na+ from the kidney tubule back into the capillar...
