Assume the po2 in a resting tissue is 40 mmhg. how much of the total o2 bound to hemoglobin in arterial blood will be released as the blood moves through the tissue capillary beds? assume that the %hb saturation is 99% in arterial blood. hemoglobin saturation, % 40 60 80 resting cell po, (mm hg) 100 alveoli
a) about 25%
b) about 60 mmhg
c) about 75%

maritime tropical may be your answer.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

d. groundwater flows through the subsoil and deposits minerals.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
