Question

The functions of bone tissue follow its structure. In bone tissue, the strong collagen fibers give bones tensile strength (flexibility) and resistance to pulling force; while the inorganic salts (calcium hydroxyapatite and other mineral salts) give bones compression resistance (resistance to compression and heavy weights). If the bones are treated by the following treatments: Bones baked for 2 hours at 400°F (hint for answering question: which component of bone tissue is destroyed by baking?) Bones soaked in 1M Nitric acid for 6 hours (which component of bones tissue is eaten away by acid?) 1) Please predict whether the bones become softer or brittle after they are treated with nitric acid. (2 points) Please explain the reason for this change. (4 points) 2) ) Please predict whether the bones become softer or brittle after they are baked for 6 hours? (2 points) Please explain the reason for this change. (4 points)
