Answer:
vasoconstriction of capillaries.
baroreceptors in the aortic arch.
Explanation:
Vasoconstriction of capillaries and baroreceptors in the aortic arch are the two quick responses of body to maintain normal blood pressure during hemorrhage. Vasoconstriction is very necessary for lowering acute blood loss during hemorrhage means escape of blood from a ruptured blood vessel as well as maintain body heat and arterial pressure. The function of baroreceptors is to respond to the change in the tension of the arterial wall when blood pressure changes.
This is known as Pancytopenia.
The three hematopoietic cell lines lead to the formation of red blood cells, white blood cells and platelets. All these cells play important roles in various body functions.
Pancytopenia is a condition in which the quantity of red blood cells, white blood cells and platelets decrease in the body of a person. Chemotherapy and radiation are serious procedures that along with killing the cancerous cells also destroy many of the normal cells of the body. Hence, chemotherapy and radiation leads to decrease in all the three hematopoietic cell lines of the body causing a condition referred to as Pancytopenia.

Answer:
What was once a continuous population is divided into two or more smaller populations. This can occur when rivers change course, mountains rise, continents drift, or organisms migrate.

It might just be unfavorable habitat between the two populations that keeps them from mating with one another.
Explanation:
Reproduction of new cells because if you were seriously burned the cell tissue would be dead and new cells need to grow to take the place of old cells
Purines bases are ADENINE(A) and GUANINE(G), and pirimidines bases are CITOSINE(C) and TIMINE(T).
In DNA, with ADENINE complementary base is TIMINE, and with GUANINE complementary base is CITOSINE.
