hormones produce detrimental and undesirable side effects (even more so in women) such as hypertension, fluid retention, decreased breast size, and a deepening of the voice.

Human growth hormone.

Explanation:

Human growth hormone is released by anterior pituitary gland. This hormone regulates body composition, fat metabolism, growth and development of an organism.

Deficiency or excessive production of human growth hormone can cause undesirable and detrimental side effects in both men and women. The unbalance amount of human growth hormone can cause fluid retention, deepening of voice, decreased breast size, hyper tension and heart related problems.

Thus, the hormone is human growth hormone.

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.
