Explanation:

Question 1:

Natural selection is not random. It acts on heritable traits, favoring those that increase survival/reproduction in a given environment. Traits that help organisms survive and reproduce are selected, so it's a non - random process based on fitness.

An adaptation is a trait that becomes common in a population over generations because it enhances survival and reproduction. It is passed down and becomes prevalent in the whole population across generations as those with the trait are more likely to reproduce.

Mutations are the source of new genetic variation. Natural selection acts on existing genetic variation (including that from mutations). For natural selection to act on a new trait, the mutation (which creates new alleles/traits) must occur first to provide the variation that natural selection can then select for or against.

Answer:

False
