Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What two minerals are bones primarily made up of?
A
Carbon and Nitrogen
B
Calcium and Phosphorus
C
Gold and Silver
D
None of the above
Explanation: 

Detailed explanation-1: -The major minerals found in bone are calcium and phosphorus in the form of an insoluble salt called hydroxyapatite [chemical formula: (Ca)10(PO4)6(OH)2].

Detailed explanation-2: -Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.

Detailed explanation-3: -Among micronutrients, calcium (Ca) and inorganic (i) phosphate (P) are the two main constituents of hydroxyapatite, the bone mineral that strengthens the mechanical resistance of the organic matrix. Bone contains about 99% and 80% of the body’s entire supply of Ca and P, respectively.

Detailed explanation-4: -The process of bone formation requires an adequate and constant supply of nutrients, such as calcium, protein, magnesium, phosphorus, vitamin D, potassium, and fluoride.

Detailed explanation-5: -Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it’s needed by other parts of the body.
