The human body maintains all of its cells' internal concentration _ to internal body fluid.
Correct answer: A. Isotonic
- A. Isotonic
- B. Hypotonic
- C. Hypertonic
- D. Hyposmotic
- E. Hyperosmotic
Explanation
The human body maintains an isotonic environment, which means that the concentration of solutes is equal inside and outside of the cells. This helps to maintain a stable internal environment and prevent damage to cells from osmotic imbalances.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
