What Makes a Bone Unique from Other Connective Tissue

Question

What makes a bone unique from other connective tissue?
A) Its strength
B) Its matrix
C) Its hardness
D) Its density

Accepted Answer

The matrix of bone is unique because it contains a combination of hard mineral deposits (such as calcium hydroxyapatite) and collagen fibers. This gives bone its strength and hardness, but also allows for some flexibility and resistance to fractures. While other connective tissues may have some degree of mineralization (such as cartilage), they do not have the same unique matrix as bone.
