From the schematic above: why do nonpolar molecules have a difficult time passing through the bilipid layer?
A)The nonpolar molecules are too large for the space through which they need to pass.
B)The nonpolar molecules are repelled by the polar water molecules.
C)The nonpolar molecules have a difficult time getting past the ionic heads of the fatty acid molecules, which are surrounded by water molecules.
D)Nonpolar molecules tend to bind with the bilipid layer, thus inhibiting their passage.
