Answer:

-from an area of higher concentration to an area of lower concentration

-without energy

-down the concentration gradient

Explanation:

Simple diffusion does not require energy. This is likely what the question is referring to.

An example of simple diffusion:

If you blow up a balloon and then poke a small hole in it. The air will leak out from the high concentration inside the balloon to the low concentration outside of the balloon. It does not require any energy to be put it--it leaks out on its own as long as there is a hole.

Answer:

-from an area of low concentration to an area of high concentration

- without energy

- down the concentration gradient

Explanation:

The movement of molecules from an area of low concentration to an area of high concentration, without energy, down the concentration gradient is correct.
