Question

multiple choice question
the concentrations of solutes between the interior and the exterior of a cell or organelle may be chemically different because the ______ is selectively permeable.
○ cytoplasm
○ dna
○ membrane
○ atp
need help? review these concept resources.

Explanation:

The cell membrane or organelle membrane is selectively permeable, controlling the movement of substances in and out. This property leads to chemical differences in solute concentrations between the interior and exterior. Cytoplasm is the jelly - like substance inside the cell, DNA contains genetic information, and ATP is the energy - carrying molecule, none of which are selectively permeable in this context.

Answer:

C. membrane
