Question

the concentration of solutions can be expressed as macromolecules active transport osmosis osmolarity atp

Explanation:

Osmolarity is a measure of the concentration of a solution, representing the number of osmoles of solute per liter of solution. Macromolecules are large - sized molecules, active transport is a cellular process, osmosis is the movement of water across a semi - permeable membrane, and ATP is an energy - carrying molecule. None of the others directly represent solution concentration.

Answer:

osmolarity
