20 POINTS PLEASE HURRY Bicarbonate ions are formed when carbon dioxide combines with:

A) Plasma

B) water

C) oxygen

D) ions.

D) Ions.

Explanation:

Carbon dioxide levels, blood pH, and body temperature affect oxygen-carrying capacity (Figure 20.20). When carbon dioxide is in the blood, it reacts with water to form bicarbonate (HCO−3) and hydrogen ions (H+). As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases.

multiply it by 5 in order for you to understand i cant give an exact answer.
