Question

(4) Why can bones not be folded?​

Answer 1

The bone is made mostly of collagen. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes the bones strong and flexible enough to withstand stress. Thus the bone cannot be folded.
