Q Boch of the regular intravenous solutions administered in medicine, normal saline and lactated Ringer's solution, are soconic. Why is this important 10

Explanation / Answer

In osmosis the movement of water (or solvent) is from the area of high water concentration to the area of low water concentration through a semi permeable membrane.

The principle force for driving movement in duffusion is the concentration gradient.

The problem faced by organism living in fresh water is that their body takes too much water from their surrounding. There is a water intake and solute molecules goes out of the body.
