Which of the following explains one way that breathing and cellular respiration are connected?

A. Breathing supplies the carbon dioxide used in respiration.

B. Breathing supplies the oxygen used in respiration.

C. Respiration removes the harmful carbon dioxide that is produced from breathing.

D. Respiration supplies the oxygen used in breathing.

The one way in which breathing and cellular respiration are connected can be denoted by option C - Respiration removes the harmful carbon dioxide that is produced from breathing.

Cellular respiration and breathing are different yet they are closely related. When we breathe in, we take in oxygen that our cells need for cellular respiration. When we breathe out, we get rid of the carbon dioxide that our cells produce during cellular respiration.

A or B are my best guess.-.
