What will happen if the cartilage of our nose is replaced by a bone?

Nose can easily be fractured

Explanation: Cartilage is a soft bone that can be found in various parts of the body e.g. ears and nose. If we replace cartilage with a bone in the nose, as a result chances of fracture increases, if something hard would hit the nose.

Elastic cartilage is found in our nose. It has two components water ( 85%) and matrix (that consist of collagens, proteoglycans, and noncollagenous proteins)
