Question

How do you know that bone is a living material?
My Answer (and think) - it contains cells

I need a bit help on this qs.
My teacher won't accepted this so I have to add more details.

Answer 1

IT does have cells, it grows, its cells reproduce (bones grow), and it has blood flow getting food from the blood.

Answer 2

Bones grow in children. When a child or adult breaks a bone, it heals and reunites in a few weeks.
