Question

the spreading out of molecules from a center of higher concentration is the result of
multiple choice
the use of atp at membrane channels.
the molecules trying to move to an area of lower concentration.
the random movement of molecules.
the changes in turgor pressure.
the concentration of molecules.

Explanation:

Diffusion is the spreading out of molecules from an area of higher concentration to an area of lower concentration. It is driven by the random movement of molecules. Using ATP at membrane - channels is active transport. Turgor pressure is related to plant cells and is not the cause of simple molecular spreading. The concentration of molecules is a condition, not the cause of the spreading process.

Answer:

C. the random movement of molecules
