What factors determine if a species is fit to survive?
Tresset [83]

Answer: variation, reproduction, and heritability.

Explanation:  Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.  

All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.

Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.

Tatiana [17]

In the citric acid cycle, the acetyl group of each molecule of acetyl-CoA is converted into two molecule of carbon dioxide and water. It is the pathway that connects carbohydrates ,fat and protein metabolism.

The cycle which carried out by eight enzymes that completely oxidase acetate by which two carbon molecules in the form of acetyl -CoA into two carbon dioxide and water molecules.6- carbon glucose molecule is split into two 3- carbon molecules called pyruvate , which needs in order to create acetyl CoA.
