QUESTION:
1 answer:
The molecules move in and out of the cell by active and passive transportation. As a result of the active transportation molecule B will move inside the cell. Thus, option B is correct.
<h3>What is active transport?</h3>Active transport is a type of transportation where the substances move from the region of the lower to higher concentrations, against the gradient.
The movement against the gradient uses energy like ATP to facilitate the ion movement from less to a more concentrated area of the substance. Molecule B has less concentration outside the cell and can move against the gradient.
Therefore, in option B. molecule B will move inside the cell through active transportation.

Your question is incomplete, but most probably your full question was, The diagram below represents a cell and the relative concentration of several molecules inside and outside of the cell. Which molecule could only enter the cell as a result of active transport?
- molecule A
- molecule B
- molecule C
