Answer 1

Ans:- 1.b

Aldosterone,

The amount of potassium secreted by the kidneys is regulated by Aldosterone.

2. C

Plasma and RBC's

In plasma and RBC's co2 reacts with water and form h2co3.

3. b

Hypoventilation,

Hypoventilation is the respiratory response to alkalosis .

4.a

Buffer system of plasma,

Buffer system of plasma is the most effective long term protection against ph changes of the body fluids.

5.b

Metabolic alkalosis,

In metabolic alkalosis , level of bicarbonate increases in the blood due to the loss of the acid from the body.
