Question

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

Explanation:

Hydrophilic (water - loving) phosphate - containing heads interact with water. Hydrophobic (water - fearing) fatty acid tails avoid water. In a phospholipid bilayer, heads face outward (towards water in intra - and extracellular environments) and tails face inward (away from water).

Answer:

attracts; repels; the intra - and extracellular environments; inward
