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 total number of solute particles per liter of solution. Macromolecules are large molecules. Active transport is a process of moving substances across a membrane. Osmosis is the diffusion of water across a semi - permeable membrane. ATP is an energy - carrying molecule.

Answer:

osmolarity
