<span>The answer to the first question is letter B. This is because disruptive selection is opposite to stabilizing selection which decreases genetic variation or genetic diversity. Among the choices on the second question, the second option (B) is the most plausible because it could mean "difference within the same specie".

if you are looking for an alphabet letter, I believe Haploid cells are symbolized by a lowercase n, which then alludes to the present number of chromosomes in the sex cell.

White blood cell classification
Blood stasis, changes in the vessel wall, and certain medications affect the ability of the blood to effectively clot.
Explanation:
Clotting is also known as blood coagulation. It is the process by which blood forms a clump which is either gelatinous or semisolid in state.
Clotting is very necessary because it prevents unnecessary loss of blood in case of cuts and injuries.
However the tendency of blood to form random clots is also very harmful because it might lead to blockage in the blood vessels.
Effective blood clotting can result from:
- Blood stasis, a condition in which the flow of blood in the vessels is hindered,
- Changes in vessel walls.
- Certain medication that prevents blood clotting or decreases blood density.
