A. decreases, increase

B. decreases, decrease

C. increases, decrease

D. increases, increase

A) Decreases; increase

Explanation:

When there are high levels of carbon dioxide in the respiratory system, the blood pH level decreases, causing respiratory rate to increase.

This condition is acidosis because not enough CO2 escapes lungs hence CO2 accumulates and decreases pH of blood, making it more acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing to increase the amount of carbon dioxide exhaled to bring our body to the ideal pH.
