Answer;
Hydrophobic
Explanation;
-The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid "tails" and a hydrophilic "head" consisting of a phosphate group.
-The lipid bilayer is arranged in two layers of phospholipids with the hydrophilic heads forming the outer edges and the tails forming the interior. In this arrangement, the bilayer has a hydrophobic core that prevents the passage of polar molecules while allowing the relatively free diffusion of non-polar molecules.
