Answer:
C. Cell membranes are composed of a lipid bilayer.
Explanation:
The cell membrane delimits the contents of the cell. A typical cell membrane is largely made up of phospholipids. Other components include the glycolipids, sterols, and proteins. The phospholipids component arrange themselves in a double layer (bilayer), forming a hydrophobic core.
<em>Fat soluble molecules are able to permeate across the cell membrane due to the lipid bilayer components - lipid in itself being a form of fat.</em>
