Which three of the statements are true? (a) hydrophobic molecules clump together in water because fewer water molecules are required to surround them, which results in a smaller decrease in entropy than if the molecules were individually hydrated. (b) hydrophobic molecules are individually hydrated in water, increasing the entropy of the system. (c) polar molecules are capable of forming micelles. (d) amphipathic (amphiphilic) lipids are the structural basis of biological bilayer membranes. (e) the tendency of water to minimize its contact with nonpolar substances is called the hydrophobic effect.
