Answer 1

Molecules tend to move spontaneously down their chemical gradient through diffusion.

Step-by-step explanation:

Molecules tend to move spontaneously down their chemical gradient. This means that they move from an area of higher concentration to an area of lower concentration. This movement is known as diffusion, which is the passive movement of particles from an area of higher concentration to an area of lower concentration.
