which element occurs more in bones

Options

A. Ca and Mg
B. Mg and Mn
C. Ca and P
D. Ca and Fe

Answer

**Step-by-Step Solution:**

1. **Understanding Bone Composition**: Bones are made up of a matrix that serves as a reserve for various elements. This matrix contains both macro elements and trace elements.

2. **Identifying Macro Elements**: The primary macro elements found in bones include Calcium, Phosphorus, Magnesium, and Sulphur. These elements play crucial roles in the structure and function of bones.

3. **Identifying Trace Elements**: In addition to macro elements, bones also contain trace elements such as Iron, Manganese, Zinc, and Cadmium. However, these trace elements are present in much smaller quantities compared to macro elements.

4. **Determining the Most Abundant Elements**: Among the macro elements, Calcium and Phosphorus are the most abundant in the bone matrix. Calcium is often found in the form of Calcium Carbonate.

5. **Evaluating the Options**:
- Option 1: Calcium and Magnesium – While Calcium is abundant, Magnesium is not the most abundant element.
- Option 2: Magnesium and Manganese – Both are not the most abundant elements in bones.
- Option 3: Calcium and Phosphorus – This is correct as both are the most abundant elements in bones.
- Option 4: Iron and Manganese – Both are trace elements and present in lesser amounts.

6. **Conclusion**: The correct answer is **Calcium and Phosphorus**, as they are the elements that occur most in bones.
