Answer:
The interior of a cell membrane is hydrophobic. The correct letter is C.
Step-by-step explanation:
The Cell Membrane is the boundary between the cell and its environment. It is a thin semipermeable membrane that surrounds the cytoplasm of a cell. It regulates what goes in and out of the cell. It consists of a phospholipid double layer.
The polar portions of the phospholipids contact the aqueous solvent and their long hydrophobic portions lie within the membrane, away from water. For this reason that the interior of a cell membrane is hydrophobic and for this reason the correct assertive about this question is letter C. Hydrophobic.
