Answer 2

4) Protein located in bones is OSSEIN.

• OSSEIN Protein is basically an organic extracellular matrix component present in the bone which is mainly constituted by collagen.

5) Vitamin B3 (Niacin) can produce NADH2.

• Basically, Vitamin B3 gets converted to Nicotinamide, which in turn gets converted to NADH2.

6) Both somatic and stem cells divide by mitosis.

• Because, the daughter cells have the same number of chromosomes as compared to the parent cells.

7) Prophase is the first step of karyokinesis.

• Karyokinesis is also known as MITOTIC STAGE.

8) Diplatin is not involved in mitosis.

9) We get 9 KCal/g energy from lipids.

10) Humans have 23 pair (i.e. 46) chromosomes (22 pair of somatic chromosomes and 1 pair of sex chromosomes).
