Answer 1

The correct option is B

Thymus-Starts undergoing atrophy after puberty.

The correct option is (B).

Explanation for correct option:

1. Thymus is located behind the sternum in the front part of the chest.

1. Calcification is caused due to increased production and deposition of calcium ions in the tissues.
2. Parathormone increases the level of calcium ions in the blood by releasing calcium from the bones to the blood.

Option D:

The beta cells of the Islets of Langerhans are responsible for the secretion of insulin that promotes glycolysis.

Final answer:
