Answer 1

Answer:

I'm fairly certain your answer is: C. (The cell membrane controls what enters and leaves the cell.)

Explanation:

In the definition of a cell membrane it says that its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out. With this definition in mind, C would make the most sense.
