a. cartilage
b. tendons
c. joints
d. ligaments
what is the role of osteoclasts in bone remodelling?
a. storing minerals in bones
b. breaking down old or damaged bone tissue
c. transporting nutrients to bones
d. forming new bone tissue
what type of bones are the vertebrae classified as?
a. long bones
b. irregular bones
c. flat bones
d. short bones

Explanation:

1. For the first question: Cartilage cushions joints, joints are the connection points between bones, ligaments connect bone to bone, while tendons are the structures that attach muscles to bones.
2. For the second question: Osteoclasts are specialized cells that break down and resorb old or damaged bone tissue, which is a key part of bone remodeling. Osteoblasts form new bone, and nutrient transport/mineral storage are not their primary roles.
3. For the third question: Vertebrae have an irregular shape that does not fit the long, flat, or short bone categories, so they are classified as irregular bones.

Answer:

1. b. Tendons
2. b. Breaking down old or damaged bone tissue
3. b. Irregular bones
