Explanation:
A. Following deep breathing of room air, the partial pressure of oxygen in plasma will increase because of higher concentrations of oxygen.
B. Following deep breathing of room air, the partial pressure of carbon dioxide in plasma will decrease because because of higher concentrations of oxygen and increase in oxygen uptake by the lungs.
C. Following deep breathing of room air, respiratory drive will decrease of saturation of blood and tissue with oxygen.
D. Following deep breathing of room air, plasma oxygen content will remain fairly constant or change just slightly because the oxygen saturation levels will have been attained.
E. Following deep breathing in and out of a small paper bag, respiratory drive will increase because of the higher levels or increase in partial pressure of carbon dioxide
F. Following deep breathing in and out of a small paper bag, plasma carbon dioxide content will increase as carbon dioxide are produced from exhalation while oxygen is not being replenished.
Answer:
co-dom: both traits show without either completely masking each other: red flower x white flower = pink offspring.
incomplete: both traits show but dont mask: red x white = red and white flower
simple: one dominant trait masks the recessive trait, red x white (where red is dominant) = primarily red flowers (depending on if the flowers are heterozygous or homozygous there will be a different number of red flowers, with a minimum of 2/4).
