Question

The Group VA element that makes up part of bones and teeth is:

• A. N
• B. P
• C. As
• D. Sb

Answer 1

The correct option is B P

Teeth are composed of calcium, phosphorus, and other minerals. Bones contain calcium, phosphorus, sodium and other minerals, but mostly consist of the protein collagen. Collagen is a living, growing tissue that gives bones their a flexible framework that allows them to withstand pressure. Calcium fills in the space around that framework and makes the bone strong enough to support the body's weight.
