The use of proteins in a cell
membrane to move molecule from a
low concentration on one side to a
high concentration on the other.

The use of proteins in a cell  membrane to move molecule from a  low concentration on one side to a  high concentration on the other is done by membrane transport proteins (Carrier proteins)

Explanation:

Carrier- mediated transport can be described as a type of transport in which carrier molecules assist in the movement of molecules inside or outside the cell.

There are two types of membrane transport proteins:

Channel proteins can be described as proteins which open channels in the cell membrane. Molecules tend to move along the concentration gradient i.e from a higher concentration to a lower concentration through this phenomenon.

Carrier proteins can be described as proteins which open in one direction only. The facilitate the movement of molecules against the concentration gradient i.e from a lower concentration to a higher concentration.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
