Final answer:
Bone is a connective tissue that contains an organic matrix composed of collagen and elastic fibers, providing strength and flexibility. It also has an inorganic matrix made up of mineral salts, primarily calcium salts, which contribute to its hardness and rigidity.
Step-by-step explanation:
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts-mostly calcium salts-that give bone its hardness and rigidity.
