Answer:
The correct answer is "the fluid-mosaic nature of the membrane".
Explanation:
The fluid-mosaic model of a cell's membrane basically describes the membrane as a a tapestry of several types of molecules that are in constant movement. The fluid-mosaic nature of the membrane helps to serve its purpose as a barrier and helps to repair small damages by the physicochemical properties of lipids. A small damage such as making an injection of a nucleus would be repaired by the fluid-mosaic nature of the membrane, which would not had happened if the procedure was done in an hypothetical membrane with a rigid structure such as a basketball.
