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).
Starch cannot diffuse across the membrane because starch molecules are too large to fit through the pores in the dialysis tubing, whereas iodine is a smaller molecule and therefore can diffuse across.
