Question

complete the paragraph to describe the phospholipid bilayer.
the environments inside the cell and outside the cell both contain water. the water the fatty acid tails and the phosphate - containing heads of the phospholipids. so the tails of the phospholipids face, and the heads face in the lipid bilayer.

Explanation:

Hydrophobic (fatty acid tails) repel water. Hydrophilic (phosphate - containing heads) attract water. In a cell, with water inside and outside, tails (hydrophobic) face inward (away from water) and heads (hydrophilic) face outward (toward water).

Answer:

The water repels the fatty acid tails and attracts the phosphate - containing heads of the phospholipids. So the tails of the phospholipids face inward, and the heads face outward in the lipid bilayer.
