Question

A group of scientist wants to test the effects of increased ocean acidity on a population of Coral. What result from this experiment would show natural selection at work?
1- three or more new species develop in the next generation
2- Growth of a thicker exoskeleton by individual coral
3-Migration of the squirrel population to marine areas with lower concentrations of acid
4-Variation in the survival and reproduction of individuals over the next several generations

Answer 1

Answer:

4-Variation in the survival and reproduction of individuals over the next several generations.

Explanation:

(It's on the review and this was the correct answer.)

So, we know that each individual within a species has slightly different genetics from one another, known as genetic variation. Because of this that means some individuals will have certain traits or characteristics that are more helpful than others. So, the ones with helpful traits are more likely to survive and reproduce than others. Meaning there will be variation in survival and reproduction of individuals over the next several genertations based on which individuals are more fit for the increased acidity.
