The plasma membrane is composed of a phospholipid bilayer and associated proteins. What else is commonly found in the plasma membranes of animal cells?

See the answer and explanation below, please.

Explanation:

The plasma membrane is composed of:

- Lipid bilayer (highlights: phosphoglycerides such as phosphatidylethanolamine or cephalin, phosphatidylcholine or lecithin, phosphatidylinositol and phosphatidylserine; sphingolipids formed by ceramide and fatty acids, and cholesterol)

- Proteins: integral, peripheral and membrane fixed to lipids.

- Glucids: covalently bound to proteins or lipids; they can be poly or oligosaccharides. They form the glycocalix on the outside of the membrane and its function is to support the membrane and cell recognition.

the answer is c.) there is a warm front in region a and a stationary front in region b.
