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).

Paul Zamecnik and his colleagues carried
out an experiment to track the fate of radioactive leucine molecules attached
to tRNAs (Transport RNAs). In their experiment, they found out that amino acids
are transferred from tRNAs to proteins. Paul Zamecnik, an American scientist, played
a major role in the early history of molecular biology.

Fortunately, these antibodies stick around for several months and are able to give newborns an added level of protection from many routine illnesses during this important time when they are not as able to effectively make their own antibodies.
