Consider the arteriolar end of a capillary bed. During capillary exchange, the process of filtration is favored at the arteriolar end due to the higher hydrostatic pressure.

Explanation:

The net filtration pressure at the arteriolar end of the capillary bed is more than 10mmHg. That is why the fluid exits capillary since capillary hydrostatic pressure is 35mmHg that is greater than blood colloidal osmotic pressure which is 25mmHg.

Hence during capillary exchange, the process of filtration is favored at the arteriolar end due to the higher hydrostatic pressure.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
