question 1 of 13
the fluid mosaic model describes the plasma membrane as having:
a rigid and static structure composed primarily of carbohydrates.
a dynamic and fluid structure where proteins and lipids can move laterally within the bilayer.
a selectively permeable barrier made only of protein channels.

Explanation:

The fluid - mosaic model describes the plasma membrane as a dynamic and fluid structure. Proteins and lipids can move laterally within the lipid bilayer. It is not a rigid and static structure mainly composed of carbohydrates, nor is it a selectively permeable barrier made only of protein channels.

Answer:

A dynamic and fluid structure where proteins and lipids can move laterally within the bilayer.
