Question

carbon dioxide (co₂) is created by cells all over the body as a waste product. it is a small 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. diffusion is a form of passive transport. 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.

Explanation:

Diffusion is passive transport. CO₂ uses simple diffusion as it's small and non - polar and unassisted diffusion through phospholipid bilayer is simple diffusion.

Answer:

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