which organ is responsible for helping to keep the water concentration equal on each side of the cell membrane?
(please help I've been stuck on this for 2 days)

Answers

Answer:

solute membrane

Explanation:

Kidney is the main organ which is responsible for helping to keep the water concentration equal on each side of the cell membrane.

What is Kidney?

The kidneys are the main organs in the body which remove waste products and extra water from the blood in the form of urine and also help to keep the chemicals such as sodium, potassium, and calcium balanced in the body. The kidneys also secrete hormones which help control blood pressure and stimulate bone marrow to make red blood cells.

Kidneys maintain water concentration in the body. Kidneys maintain homeostasis through osmosis. Osmosis is the phenomenon of movement of water or fluid particles from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
