The correct answer is: B.Gases like oxygen and carbon dioxide diffuse freely across the membrane.

Oxygen (O₂) and carbon dioxide (CO₂) are small, nonpolar molecules, which allows them to diffuse freely across the lipid bilayer of the cell membrane via simple diffusion. This process does not require energy or any transport proteins.

In contrast:

A.Gases like oxygen and carbon dioxide move via active transport is false. Ac...
