Answer:
A. The model illustrates active transport because energy is required for solute particles to cross the cell membrane.
Explanation:
Active transport is the transport of molecules from a region of lower concentration to a region of higher concentration. In other words, movement occurs against a concentration gradient.
Due to this, it requires energy in form of ATP for this movement to occur. Hence, based on this question, the model illustrates active transport because energy is required for solute particles to cross the cell membrane.
Answer:
