Answer:The cell membrane functions as a barrier that makes it possible for the cytoplasm to maintain a different composition from the material surrounding the cell.

It is permeable to small molecules in inverse proportion to their size but in direct proportion to their lipid solubility.
Explanation:
I would say that the most correct statement is the following one:
Certain types of renewable energy can be used for as many applications as certain types of nonrenewable resources.

A nucleus controls the movement of the cell, if that helps.
Characteristics should be in the blank
