6 a substance that moves across a cell membrane
without using the cell's energy tends to move
(1) away from the area of equilibrium
(2) away from the area where it is less
concentrated
(3) away from the area where it is more
concentrated
(4) toward the area where it is more
concentrated

3) away from the area where it is more  concentrated

Explanation:

A substance that moves across a cell membrane  without using the cell's energy tends to move away from the area where it is more  concentrated.

It is known as passive transport.

It is the process in which substance without using the cellular energy tend to move down the concentration gradient.

It is also known as simple diffusion.

All other options are incorrect because,

In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.

This process require energy.
