<span>When a gene changes within a population over time, it is referred to as evolution. This refers to a long but steady rate of mutations that occur in genes of organisms within the environment. A lot of factors affect a population's evolution (e.g. climate, reproduction, food source) and it is a determinant whether a species will survive for the next generations. </span>
In chromatin, substitution mutations are most common in linker regions. Option d is the correct answer.
Mutation by substitution When one nucleotide base is replaced by another, this occurs. Mismatch mutation A type of substitution mutation in which a single nucleotide is replaced, resulting in the coding of an incorrect amino acid, which usually results in a malfunctioning protein. Silent mutations are the result of genetic code redundancy (degeneracy): This is false, as silent mutations are the result of a base substitution that has no discernible effect on a protein's amino acid sequence.

Homeostasis is balance. The shortest answer to your essay is that these 3 systems remove toxins from the body. Some of these toxins are in the air & food we take in, and some are just waste products after we process food.
The digestive system takes the food we eat, pulls out the energy we need to move and live, and passes on the waste to be excreted. If it didn’t excrete the waste, toxins would build up in the body.
The urinary system maintains homeostasis by filtering toxins out of the blood, and deciding how much water should be retained or wasted, based on our blood’s chemistry.
Another part of the excretory system is our skin. We sweat out toxins from exercise.
I hope these ideas are helpful to get to through your essay.
