Answer:
Passive transport involves movement of substances from areas of higher concentration to areas of lower concentration.
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 <u>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</u>, following the so-called concentration gradient. Theoretically, the gradient tends to disappear when the concentrations of substances have balanced out.
Regarding other options:
<em> A. </em><u><em>From areas of lower concentration to areas of higher concentration</em></u><em>. It is a feature of active transport.</em>
<em> C. </em><u><em>From areas in which the concentration has reached a balance</em></u><em>. There is no passive transport</em>
<em> D. </em><u><em>From areas of differing concentrations with the use of cellular energy</em></u><em>. Energy use involves active transport.</em>
