Which refers to the maintenance of a stable internal environment despite changing external conditions? differentiation self-renewal homeostasis specialization

homeostasis

Explanation:

Living systems have the ability to maintain a stable internal environment despite changes in their external environment. The process by which they do this is called HOMEOSTASIS. Homeostasis is important for the optimal functioning of internal organs in living organisms.

An example of homeostasis is the regulation of body temperature in humans. The body uses internal mechanisms to ensure that the body temperature is kept at a stable state irrespective of the changes in environmental conditions that could affect it.

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.
