i dont know yet

Explanation:

The plasma - membrane has a lipid - bilayer structure. Hydrophobic molecules can dissolve in the lipid bilayer and pass through the plasma membrane more readily. Hydrophilic molecules, on the other hand, have difficulty passing through the non - polar lipid bilayer. Larger molecules have more trouble passing through compared to smaller ones, and charged molecules are repelled by the non - polar environment of the lipid bilayer.

Answer:

C. Hydrophobic; hydrophilic
