Human bone cells contain _ % of water.
Correct answer: A. 20
- A. 20
- B. 40
- C. 85
- D. 90
Explanation
Bone is a complex and rigid connective tissue that contains various components, including cells, fibres, and minerals. Human bone cells contain around 20% water content. This water is present within the extracellular matrix, filling the spaces between the collagen fibers and mineralized crystals.

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.
