Bone tissue consists of what percentage of organic substances?

• A. 50%
• B. 25%
• C. 10%
• D. 75%

Answer: (B)

Bone tissue is composed of approximately 25% organic substances. These organic components primarily consist of collagen fibers and proteins that provide flexibility and tensile strength to the bone. The correct percentage highlights the structural makeup of bone, emphasizing the balance between organic and inorganic materials. The inorganic portion primarily includes minerals such as hydroxyapatite, which gives bone its hardness and rigidity. This composition is crucial for maintaining the strength and durability of bones while allowing for some degree of flexibility to prevent fractures. Understanding this percentage helps in comprehending the biological function and adaptability of bone tissue in the human body.
