Which three of the statements are true? Hydrophobic molecules are individually hydrated in water, increasing the entropy of the system. 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. Polar molecules are capable of forming micelles. The tendency of water to minimize its contact with nonpolar substances is called the hydrophobic effect. Amphipathic (amphiphilic) lipids are the structural basis of biological bilayer membranes.
