    A shark's skeleton is made out of...

    • Minerals

    • Cartilege

    • Bone

    • It has no skeleton

    Correct Answer
    A. Cartilege
    Explanation
    A shark's skeleton is made out of cartilage. Cartilage is a flexible and lightweight connective tissue that provides support and structure to the shark's body. Unlike bone, cartilage is not as hard and rigid, allowing the shark to move more easily and efficiently in water. This adaptation is beneficial for the shark's swimming and hunting abilities. Additionally, cartilage is more resistant to damage and does not require constant repair and maintenance like bone does.
