Step-by-step explanation:

Active transport is the movement of molecules across a cell membrane from a region of low concentration to a region of high concentration. This is done using energy.

According to this, we can conclude that option 2) is false: a substance moves from an area of high concentration to an area of low concentration.

We can conclude that the correct answer is:

Answer:

A substance moves into or out of a cell using energy.
