In a single sentence, explain the relationship between pancreas and homeostasis.

The pancreas produces insulin that control with great accuracy the amount of glucose sugar in the blood.

Explanation:

It is important that glucose is maintained at a certain constant level, first because this sugar is the body's main source of energy, and secondly because even slight changes in glucose concentration alters the bloods osmotic pressure, altering water movement rate in and out of the body by osmosis. Therefore, when their is increase in bloods glucose level, the pancreas produces insulin.

The pancreas produces insulin which it uses to regulate the sugar in your body

Explanation:

1) gene flow

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

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.
