Human tissues have 85% of water in the cells of:
Correct answer: A. Brain
- A. Brain
- B. Bone
- C. Blood
- D. Liver
Explanation
The correct answer is the brain, which is composed of approximately 85% water. This high water content is essential for its function, as it aids in the transmission of electrical signals. The other options are incorrect because they have less water content: bone is much denser and contains about 20% water, blood is about 83% water, and the liver is approximately 70-75% water.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
