Which homeostatic process moves particles against a concentration gradient?

Active transport is a correct answer

Explanation:

Active transport is the homeostatic process in which particles move against the concentration gradient.

The molecules move across the membrane from the low concentration to high concentration.

In this process, energy is required which is provided in the form of ATP for the movement of the molecule.

There are three types of Active transport

The sodium-potassium

Example of Active transport:

Protein pump requires energy ATP to transport the molecules from the region of low concentration to high concentration.Sodium Pump is also an example of active transport.

Mg is used to measure mass

They formed the oceans.  as they melted water was formed and the water made the oceans
