Answer 1

The level of carbon dioxide in the body controls how fast you breathe.

Step-by-step explanation:

The level of carbon dioxide in the body controls how fast you breathe. When the level of carbon dioxide in the body increases, the brain sends signals to increase the rate of breathing in order to remove the excess carbon dioxide and bring oxygen into the body. On the other hand, when the level of carbon dioxide decreases, the brain signals to slow down the breathing rate. This process is regulated by the respiratory center in the brainstem.
