Leesha fell from her bicycle and fractured one bone in her forearm. The X-ray confirmed a crack, so the doctor placed her arm in a plaster cast to keep the bone steady until it healed. While explaining the treatment, the doctor told her that bones are strong because of certain minerals stored in them.

(i) Bones are classified under which type of animal tissue?

(ii) Name two minerals that make bones strong.

(iii) State one important role of bones in vertebrates apart from movement.

(iv) Mention one other tissue in vertebrates that provides support and has a structure similar to bone.

(v) Name one location in the human body where the tissue mentioned in (iv) is found.

(i) Bones are classified as connective tissue.

(ii) Two minerals that make bones strong are calcium and phosphorus.

(iii) One important role of bones (apart from movement) is protection of internal organs (e.g., skull protects the brain, rib cage protects the heart and lungs).

(iv) Another tissue that provides support and has a structure similar to bone is cartilage.

(v) One location where cartilage is found in the human body is the tip of the nose (it is also found in the ear and joints).
