Answer:
Calcitonin
Explanation:
Calcitonin hormone is released by the para follicular cells of the thyroid gland. This hormone works against the parathyroid hormone.
Calcitonin hormone regulates the level of calcium by decreasing the blood calcium level. This hormone inhibits the osteoclast activity of the cells and decreases the absorption of calcium in pregnant women and child. Hence, calacitonin decreases plasma calcium levels in pregnant women and children.
Thus, the correct answer is option (B).

Answer:
- ATP and NADPH facilitate the reduction of 6 molecules of 3-PGA (formed in carbon fixation)to six molecules of the simple sugar glyceraldehyde 3-phosphate (G3P).
- In the reduction process ADP and NADPH+ are made, when ATP releases energy and loses its terminal phosphate, and NADPH loses energy and a hydrogen atom.
- ADP and NADPH+ return to the light-dependent reactions for re-use.
Explanation:
Sugar biosynthesis in plants, called photosynthesis produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. In chloroplasts, this occurs in the light-dependent and dark reactions. In the light- dependent reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
In the light-independent reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP). Organic molecules are reduced and RuBP is regenerated.
