a.)the two layers of the plasma membrane are identical
b.) the plasma membrane is a rigid structure.
c.) the proteins on the two layers are not identical.
d.) proteins are found on only one surface of the membrane.

Answer 1

C.) The proteins on the two layers are not identical.

Answer 2

Option (C).

Step-by-step explanation:

Plasma membrane can be defined as a outer covering, present in cells of all living organisms, including both prokaryotes and eukaryotes that separate internal and external environment of the cell.

Plasma membrane is made up of lipid bilayer in which proteins are embedded. Proteins present in these two lipid bilayer have different composition and functions.

Thus,the correct answer is option (C).
