Given a scenario where a cell is exposed to a toxin, how might the cell membrane react to protect the cell?

• By becoming permeable and allowing the toxin to diffuse out.

• By selectively increasing permeability to substances that can neutralize the toxin.

• By stopping all transport processes.

• By dissolving the cell membrane to release the toxin.
