Solution:
1)(A)The most of CO2 transported by the blood in humans - CO2 attached to the hemoglobin.CO2 attached to the hemoglobin present in the blood and transported to the lungs through blood Capillaries.
2(B)Air flows in only one direction through the lungs of -Birds.Unlike human being air does not turn around in birds lungs.It is flow in one direction through the lungs.
3(A)Monocots differ from dicot in that monocots have-Leaf veins that are parallel.It have one cotyledon in the seed.Pollen with single apertures.
D) (1)All of the following normally enter the plant through the roots except-Carbon dioxide.Calcium,potassium and nitrogen all are absorbed by the plant through their roots.
