Answer:
A process of change in a population through genetic variation.
Explanation:
Evolution is the process of change in heritable characteristics of populations of organisms over several generations as it allow natural selection in it.
Genetic variation which refers to differences in gene frequencies is an important force in evolution which relies of natural selection to cause an increase or reduce gene frequencies in a population. Evolution lead to changes in genetic material of populations over time which make them to develop genes that will allow them to adapt to their environment for survival and reproduction.
The answer would be c. the new substances that are formed during the reaction. The products are what you end up with after the reaction. For instance, the products of photosynthesis are glucose and oxygen because that's what plants make as a result. The reactants are what are used to start the reaction. The reactants in photosynthesis are carbon dioxide, water and sunlight since that's what plants need in order to start the process. Hope this helped! :)
