Question

the net movement of molecules or ions from a low concentration to a higher concentration is called
facilitated diffusion
active transport
diffusion
exocytosis
osmosis

Explanation:

The question describes the net movement of molecules/ions from low to high concentration. Facilitated diffusion, diffusion, and osmosis are passive (high to low concentration). Exocytosis is bulk transport of substances out of cells. Active transport requires energy to move substances against the concentration gradient (low to high).

Answer:

active transport
