Vedclass · Answer

(B) Bones are composed of an organic matrix (primarily collagen) and inorganic mineral salts (primarily calcium phosphate). Collagen provides flexibility and tensile strength,while mineral salts provide hardness and rigidity. In children,the proportion of organic substances (collagen) is higher relative to mineral salts compared to adults. This higher organic content makes the bones more flexible and less brittle,allowing them to withstand more stress without fracturing easily. As a person ages,the mineral content increases,making the bones harder but also more brittle.
