Question

which is not an example of active transport? running heart beat osmosis moving molecules from low to high

Explanation:

Active transport requires energy and moves substances against a concentration gradient. Osmosis is a passive process where water moves from an area of high - water potential to low - water potential across a semi - permeable membrane, not an example of active transport. Running and heart beat involve energy - consuming processes in the body and moving molecules from low to high concentration is active transport.

Answer:

C. osmosis
