Bulk flow systems move substances faster than simple diffusion.
Small, but normal variations in genes may produce proteins that work differently from those of other individuals ( friends or relatives). This may affect how we respond to different medicines. The extent to which these proteins functions varies from one individual to another. Example; certain painkillers only work when body proteins convert them from an inactive form to an active one. If these proteins work too fast, the drug will be eliminated from the body before it has time to work. To do their job the pain killers need to bind and modulate a target body protein, the receptor, such that if the target body protein is altered the pain killer might not be able to bind.

The answer to number one is B, and the answer to two is D.
Answer:
AA, Aa and aa genotypes will be produced.
Explanation:
If two birds with AA and aa genotypes are crossed, 4 offspring with Aa phenotype may be produced in F1 generation.
P generation: AA x aa
/ \ / \
F1 generation: Aa Aa Aa Aa
When these F1 generation birds will be allowed to breed, the genotype of the F2 offspring will be as under:
Aa x Aa
/ \ / \
F2 generation: AA Aa Aa aa
3 types of genotypes AA, Aa and aa will be produced in F2 generation. Their ratio will be AA : Aa : aa = 1 : 2 : 1.
