Question

We can fold the cartilage of our ears but we can not bend the bones in our arms. Why?

Answer 1

Our ears are made up of a flexible material called CARTILAGE. Cartilage is also present in our nose and it is also known for making up the skeletal system of sharks.

> And secondly, our bones are made up of hard calcium. It makes up our teeth too.

> The reason for the statement is, cartilage is itself a flexible material. It can be bended due to its composition whereas bone is a really hard part of our body. It Is not flexible either way.
