Name the process that a cell will use to continue absorbing ions even when their concentration outside the cell is very low.

The process that a cell uses to continue absorbing ions even when their concentration outside the cell is very low is called Active Transport.

Here are the steps of Active Transport:

1. Active transport usually happens across the cell membrane. The cell membrane contains proteins that can move molecules from low concentration to high concentration.

2. These proteins are like pumps. They use energy to move the molecules against the concentration gradient. This energy is usually in the form of ATP (Adenosine Triphosphate).

3. The molecule that needs to be transported binds to the protein pump on the side of the cell membrane where the molecule is in lower concentration.

4. The protein pump changes shape and transports the molecule across the cell membrane to the side where the molecule is in higher concentration.

5. The molecule is released on the side of the cell membrane where it is in higher concentration.

6. The protein pump returns to its original shape, ready to transport another molecule.

This process allows cells to maintain a concentration of certain molecules that is different from the concentration in the environment. This is crucial for many cellular functions.
