Answer: covering the ends of long bones
Explanation:
Cartilages are tissues that aid in movement and protect the bones. They are usually elastic and cover bones at the joints so they are most likely found covering the ends of long bones such as the femur.
By covering these bones at the end, they protect it when weight bears on the joints so that the bones don't take too much pressure and due to their slippery nature, aid in movement as bones are able to glide over them.
