the fatty acid tails located in the lipid bilayer of the cell membrane are ______. more than one answer may be
□ fat - soluble
□ lined up so they point toward the interior of the membrane
□ water - soluble
□ lined up so they point to the watery environments on the outside of the cell

Explanation:

1. Fatty acid tails are nonpolar, so they are fat-soluble (hydrophobic) and repel water, making them insoluble in water.
2. In the cell membrane lipid bilayer, the hydrophobic fatty acid tails face inward, away from the watery environments inside and outside the cell, while the hydrophilic heads face outward toward these watery areas.

Answer:

• fat-soluble
• lined up so they point toward the interior of the membrane
