A primary active transport process is one in which <span>molecules move through transport proteins that have been activated by ATP.
</span><span>Primary active transporters, such as the sodium-potassium ATPase (or pump), are activated when ATP is hydrolyzed. This activation allows for the transport of solutes across the plasma membrane against concentration gradients.</span>

Answer:
partially permeable
Explanation:
A dilute solution contains a high concentration of water molecules, while a concentrated solution contains a low concentration of water molecules. Partially permeable membranes are also called selectively permeable membranes or semi-permeable membranes. They let some substances pass through them, but not others.
