Answer:
1 Answer. Matthew T. Both natural selection and genetic drift are mechanisms for evolution (they both change allele frequencies over time). The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success.

Mutations can happen in every stage of a cell cycle. Also most DNAs code for functional RNA not proteins. And only some mutations are beneficial not Mostly. Pay attention on the fact that in one cell we have complete set of genes but only a few of them express ( activated)
Answer:
<u>3. exothermic, because the products are at a lower energy state in the reactants</u>
Explanation:
It is also because the average enthalpy is negative.
since products are at lower energy state, the ∆H will be negative. But the negative represents loss of heat hence exothermic reaction.
