Answer:
Passive transport involves movement of substances from areas of higher concentration to areas of lower concentration.
Step-by-step explanation:
Passive transport involves the passage of substances through a semi-permeable membrane, as occurs with transport at the level of cell membranes.
Generally, passive transport occurs with the movement of compounds from the space with the highest concentration of a specific substance to the space with the lowest concentration of the same substance, following the so-called concentration gradient. Theoretically, the gradient tends to disappear when the concentrations of substances have balanced out.
Regarding other options:
A. From areas of lower concentration to areas of higher concentration. It is a feature of active transport.
C. From areas in which the concentration has reached a balance. There is no passive transport
D. From areas of differing concentrations with the use of cellular energy. Energy use involves active transport.
