Question

The role of the cell membrane is most like the job of which person?

Answer 1

Like a police officer allowing people to enter crime scenes. Possibly even a guard, or an army.

Answer 2

A gate keeper

Step-by-step explanation:

It's like a gate keeper in a hotel, a party or a nightclub. The membrane decides who goes in and who goes out, and how many of each class are allowed in either direction to maintain things stable, without getting to crowded or too loose.
