Phospholipids have both hydrophobic and hydrophilic ends. how does this structure make the phospholipid ideally suited to the selectively permeable structure needed by the plasma membrane?
a. the hydrophobic heads create a boundary that prevents water-soluble polar molecules from crossing the membrane. b. the hydrophobic tails create a boundary that prevents water-soluble polar molecules from crossing the plasma membrane but allows lipid-soluble nonpolar molecules. c. the hydrophobic heads create a boundary that prevents lipid-soluble nonpolar molecules from crossing the membrane. d. the hydrophilic heads create a boundary that prevents water-soluble polar molecules from crossing the membrane.
