Question

5 fill in the blank 1 point two layers of make up the cell membrane. phospholipids

Explanation:

The cell membrane is composed of a phospholipid bilayer. Phospholipids have a hydrophilic (water - loving) head and a hydrophobic (water - fearing) tail. In an aqueous environment (such as the inside and outside of a cell), phospholipids arrange themselves into two layers. The hydrophilic heads face outward (towards the water - based environments inside and outside the cell), and the hydrophobic tails face inward (away from the water). This bilayer structure provides a barrier that is selectively permeable, allowing the cell to control what enters and exits.

Answer:

Phospholipids
