Explanation

Tensile strength refers to a material’s ability to resist being pulled apart.

Bones have collagen fibers that provide high tensile strength.

This allows bones to withstand forces that try to stretch or bend them.

Explanation

Collagen is a structural protein that forms strong fibers in bones.

It provides tensile strength and flexibility, preventing bones from breaking easily.

Collagen works together with calcium phosphate to maintain bone rigidity.

Loss of collagen with age can lead to brittle bones and osteoporosis.
