Quizplus · Accepted Answer

Bone is a mixture of hardened collagen, which provides its strength, and minerals such as calcium and phosphate, which give it rigidity. Chondroitin sulfate is a component of cartilage, not bone. Columnar epithelial cells make up certain tissues in the body, such as the lining of the intestines, but not bone. Fibrous connective tissue is present in tendons and ligaments, but not in bone.
