Answer 1

Answer:

preventing friction between bones

Answer 2

The correct answer is B. Preventing friction between bones

Explanation:

Cartilage is a soft, and elastic tissue that protects the end of bones in articulations; although this tissue also forms structures such as the ear. In the case of cartilage in bones, the main function of this is to act as a protector for the bones by reducing the friction between them. For example, cartilage is found in the joints. This is necessary because bones are hard structures and direct friction between them would lead to deterioration of the bones. According to this, the main function of cartilage is preventing friction between bones.
