Final answer:

The fatty acid tails of phospholipids are hydrophobic and are located inside the phospholipid bilayer, away from water.

Step-by-step explanation:

The fatty acid tails of phospholipids are hydrophobic and are found in the interior of the phospholipid bilayer. Phospholipids are composed of a hydrophilic head that includes a phosphate-containing group attached to a glycerol molecule, and two hydrophobic tails, each containing a fatty acid chain. In the structure of the cell membrane, the amphipathic nature of these molecules allows them to form a bilayer where the hydrophilic heads face outward towards the aqueous environment, and the hydrophobic tails face inward, away from water.

nonpolar, inner membrane (since they are hydrophobic and tails are avoiding polar molecules)
