What do osmosis and diffusion have in common? A.) Both permit molecules of any kind, whether solute or solvent, to cross the bilayer membrane.
B.) Both require the additional energy provided by an energy carrying molecule, like ATP, to allow molecules to pass through the membrane.
C.) Both processes occur through a semipermeable membrane called a concentration gradient.
D.) Both are the net movement of randomly moving molecules that makes concentration nearly equal on both sides of a bilayer membrane.
