Question

nonpolar molecule. carbon dioxide exits cells by moving across cell membranes using a form of passive transport called simple diffusion. this video shows the simple diffusion of carbon dioxide molecules. the diffusion of carbon dioxide is called simple because carbon dioxide can diffuse directly through the phospholipid bilayer without assistance. select the true statements. carbon dioxide can move across cell membranes via simple diffusion because it is large and polar. carbon dioxide only crosses the cell membrane in one direction. the unassisted diffusion of molecules directly through the phospholipid bilayer is called simple diffusion. diffusion is a form of passive transport.

Explanation:

According to the text, carbon - dioxide diffuses through the phospholipid bilayer without assistance which is simple diffusion, and diffusion is a type of passive transport. Carbon dioxide is non - polar (not large and polar as stated in the first option), and it can cross the membrane in both directions (contradicting the second option).

Answer:

C. The unassisted diffusion of molecules directly through the phospholipid bilayer is called simple diffusion., D. Diffusion is a form of passive transport.
