During active transport, a material may be moved from an area of low concentration to an area of high concentration.
During passive transport, energy is used to move material against a concentration gradient.
During active transport, water is pumped across a membrane to equalize the concentration of salts on both sides.
During passive transport, osmosis allows salts to move from one side of the membrane to the other to equalize concentrations on both sides.

Answer;

A. During active transport, a material may be moved from an area of low concentration to an area of high concentration.

Explanation;

-Active transport involves movement of molecules or particles against a concentration gradient (from a region of low concentration to a region of high concentration). This movement of particles against the concentration gradient requires an input of energy from the cell in the form of ATP.

- Passive transport on the other hand involves movement of materials from a region of high concentration to a region of low concentration and does not utilize energy. Passive process are processes such as osmosis and diffusion.
