WILL AWARD THE BRAINLIEST!! When animal cells perform cellular respiration they produce high concentrations of carbon dioxide within the cells. The small non polar carbons dioxide molecules easily move from the inside to the outside of the cell via diffusion. How do we know that carbon dioxide leaves the cell because of diffusion?

A. The molecules of carbon dioxide move from and area of high concentration to an area of low concentration.

B. The molecules of carbon dioxide move from and area of low concentration to and area of high concentration.

C. It takes extra energy to move the carbon dioxide molecules outside the cell.

D. Carbon dioxide turn into oxygen during cellular respiration.
