Answer:
B. Mutation; C. Random genetic drift; D. Migration; F. Natural selection
Explanation:
B. Mutation: Mutations resulting from substitution, addition or deletions of a nucleotide in a sequence can alter the gene. This can be carried over a population and may be have deleterious effects or increase fitness in a gene.
C. Random genetic drift: It is a change in allele frequency that occurs by chance, usually in a small population and is carried over generations.
D. Migration: Involves the flow of a gene in or out of a population, and this modifies the allele frequency.
F. Natural selection: When fitness-promoting alleles are favored and carried over to the next generation.
Answer:
Yes
Explanation:
Because scientists have discovered waves that rise up to be taller than some sky scrapers. However, rather than being found on sunny beaches in exotic locations around the world, these waves are three miles beneath the surface of the ocean.

Answer:
The answer is 2; Lake.
Explanation:
A lake (from Latin lacus) is a large body of water (larger and deeper than a pond) within a body of land. As a lake is separated from the ocean, it is not a sea. Some lakes are very big, and people in the past sometimes called them seas. Lakes do not flow like rivers, but many have rivers flowing into and out of them.
