Answer:
The increase in the amount of carbon dioxide in in blood will lead to respiratory acidosis
Explanation:
Carbon dioxide in its normal level between 38 to 42 mm Hg plays vital roles in the human body like regulating the PH of the human blood, breathing regulation and other things. If the amount of carbon dioxide is high more than the range level, it will cause what is called respiratory acidosis.
Respiratory acidosis is a situation in cause by decrease in ventilation i.e Oxygen level leading to increase in carbon dioxide and drop in PH level of the blood.
Answer:
The correct answer is option (a)-"zone of cell proliferation".
Explanation:
