Question

which of the following is not a characteristic of an animal cell membrane? it has a fluid structure. it has a rigid structure. it has a fluid mosaic structure. it has a bilayer of phospholipids. it contains cholesterol.

Explanation:

Animal cell membranes follow the fluid mosaic model, meaning they have a fluid, flexible structure (not rigid) composed of a phospholipid bilayer, and animal cell membranes contain cholesterol to maintain fluidity. The rigid structure is a feature of plant cell walls, not animal cell membranes.

Answer:

It has a rigid structure.
