Analyze how the cell membrane contributes to homeostasis within a cell.

• By allowing all substances to freely enter and exit the cell.

• By selectively allowing substances to enter and exit, thus maintaining a stable internal environment.

• By producing energy for the cell.

• By replicating DNA.
