The passive movement of ions or molecules from a point of high concentration to a point of low concentration is known as:
A)diffusion.
B)active transport.
C)endocytosis.
D)solubility.

Question

Quizplus · Accepted Answer

Diffusion is the process of passive movement of molecules/ions from high concentration to low concentration. Active transport involves the use of energy to move molecules/ions against the concentration gradient. Endocytosis is the process of engulfing extracellular materials into the cell. Solubility is not related to the movement of ions or molecules.
