Question

Which type of solution is ideal for carrying out cell functions in the body?

Answer 1

The right answer is isotonic solutions (it contains 0.9% of NaCl).

Isotony is when a solution or medium has the same osmotic pressure than another solution or medium. This is necessary to maintain the cell structure.

In biology, an isotonic solution, is a solution that has an osmotic pressure equal to that of the blood plasma. A solution that contains 9 g of sodium chloride per liter is isotonic to blood plasma.

Other conditions may be necessary such as temperature (at 37 °c) and pH neutrality.
