Final answer:
Supportive tissues like bone derive their strength from a matrix containing collagen for flexibility and mineral salts for hardness, which together provide the essential support and protection for the body.
Step-by-step explanation:
Supportive tissues such as bone or wood derive their strength from a combination of organic and inorganic materials within their extracellular matrix. Bone, for instance, is a type of supportive connective tissue that plays a crucial role in maintaining posture and protecting internal organs. The organic matrix of bone includes collagen fibers, which provide strength and flexibility, while the inorganic matrix mostly comprises of mineral salts like hydroxyapatite (a form of calcium phosphate) that give bone its hardness. Together, these components of bone ensure it is strong yet not brittle, allowing it to recover from injuries efficiently and provide the necessary support and protection for the body.
