• For question 1: The cell membrane is a phospholipid bilayer. "Bi" means two, so a bilayer has 2 layers.
• For question 2: Hydrophilic means water - loving. The head of the phospholipid interacts with water.
• For question 3: Hydrophobic means water - fearing. The tails of the phospholipid avoid water.

Answer:
