Which statements best explains why the cell membrane assembles as a phospholipid bilayer? Select two. Membrane proteins anchor in the membrane, like scaffolds, to aid in the transportation of molecules.

Cholesterol in the membrane maintains the membrane's fluidity and reduces permeability.

Hydrophobic tails avoid interacting with polar, aqueous environments, facing the center of the bilayer.

Hydrophilic heads of the phospholipids interact with the polar, aqueous environment inside the cells, and outside the cell.
