A) result from the tendency of water to maximize contact with nonpolar molecules B) are the result of strong attractions between nonpolar molecules C) are the result of strong repulsion between water and nonpolar molecules D) depend on strong permanent dipoles ... WebMar 5, 2024 · Small nonpolar molecules can easily diffuse across the cell membrane. However, due to the hydrophobic nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot do so. Instead, they diffuse across the membrane through transport proteins.
