1. the cell membrane is like the doors or windows of a building because...

it can selectively allow certain things to go in or out of the cell.
it prevents anything from getting into the cell.
it prevents anything from getting out of the cell.
rewatch

Explanation:

The cell membrane is a selectively permeable structure. It controls the movement of substances in and out of the cell, similar to how doors and windows control what enters and exits a building. The second and third options are incorrect because the cell membrane does not prevent all substances from entering or exiting (it is not completely impermeable).

Answer:

It can selectively allow certain things to go in or out of the cell.
