Explanation:

1. Cartilage is a strong, flexible connective tissue. Ligament attaches one bone to another. Tendon attaches muscle to bone. Osteoporosis is a condition with progressive bone - tissue loss. Scoliosis is a lateral curvature of the spine.
2. The skeletal system protects internal tissues, produces blood cells, and acts as a framework for muscles, not preventing limb movement.
3. Connective tissue cushions bones, attaches bone - to - bone and bone - to - muscle, but does not prevent degenerative disorders.
4. The knee is a hinge joint.
5. In a compound fracture, the broken end of the bone cuts through the skin.
6. When ligaments attaching a bone at a joint are torn as the bone slips out of place, it results in dislocation.
