In the plasma, the quantity of oxygen in solution is
a. not present except where it is combined with carrier molecules
b. about equal to the oxygen combined with hemoglobin
c. greater than the oxygen combined with hemoglobin
d. only about 1.5% of the oxygen carried in dissolved form

D. only about 1.5% of the oxygen carried in dissolved form is correct answer.

Explanation:

Plasma is a component of blood, it has many functions in our body like fighting against diseases, clotting the blood.

In the plasma, the quantity of oxygen in solution is about 1.5% of the oxygen carried in dissolved form and 98.5% of the oxygen is bound to hemoglobin.

Thus option (D) only about 1.5% of the oxygen carried in dissolved form is correct.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
