Answer:
B
Explanation:
Directional selection tends to evolve towards one specific trait. In this example, white rabbits no longer have a competitive advantage because of disappearing snow. This means they are more easily spotted by predators, resulting in reduced fitness and less chance they will live to reproductive age and pass their recessive white alleles on.
Natural selection will favor the gray colour allele, increasing the frequency oft this previously rare allele.
A. The oceans.
That is because oceans absorb more than a quarter of the carbon dioxide that humans produce.

He or she is said to be in a positive
nitrogen balance state.
Nitrogen balance is the
traditional method of determining dietary protein requirements. Determining
dietary protein requirements using nitrogen balance requires that all nitrogen
inputs and losses are carefully collected, to ensure that all nitrogen exchange
is accounted for. Positive nitrogen balance is associated with periods of
growth, hypothyroidism, tissue repair, and pregnancy. This means that the
intake of nitrogen into the body is greater than the loss of nitrogen from the
body, so there is an increase in the total body pool of protein.
