Final answer:
The compression strength of bone matrix is due to the presence of Collagen, Proteoglycans, and Calcium salts.
Step-by-step explanation:
The compression (weight bearing) strength of bone matrix is due to the presence of Collagen, Proteoglycans, and Calcium salts. Collagen fibers provide flexibility and tensile strength to bone, proteoglycans help to resist compression forces, and calcium salts, such as hydroxyapatite, provide rigidity and strength to the bone matrix.
