Answer:

C. away from the area where it is more concentrated.

Explanation:

If a molecule is moving across a cell membrane w/o using the cell's energy, it is diffusion, which is defined as the movement of a substance from higher to lower concentration. Diffusion <em>never </em>requires energy, whether it is facilitated or not, as clustered molecules and/or atoms simply want to get the heck away from each other if in too high concentration in a single place. The type of molecular movement across a cell membrane that would require the cell's energy would be active transport, which often requires ATP or GTP and works against a concentration gradient.

Cheers.

Why are three-dimensional models useful for understanding the lunar phases?
Juli2301 [7.4K]
New moon, quarter moon, full moon are what we call the lunar phases. These are consequences of the motions of the Sun, Earth and moon. Three dimensional models are useful because the face of the moon that catches the light of the Sun depending on their position at any given time could be depicted well. Circular models would be the best visuals for the lunar phases.
