multiple choice question without the expenditure of energy, the net movement of matter in a physiological gradient will always be from a region of —— concentration to a region of —— concentration. higher; lower lower; higher

Answer

Brief Explanations:

In passive transport (without energy expenditure), matter moves down its concentration gradient from an area of higher concentration to an area of lower concentration. This is due to the natural tendency of substances to spread out evenly to reach equilibrium.

Answer:

higher; lower
