Vedclass · Answer

(B) Statement $(A)$ is correct: Hypothyroidism during pregnancy leads to defective development and maturation of the growing baby,causing stunted growth (cretinism),mental retardation,and low intelligence quotient.Statement $(B)$ is correct: Thyroxine is a lipid-soluble hormone (iodothyronine) that can cross the plasma membrane and bind to intracellular receptors. Therefore,it does not require a secondary messenger.Statement $(C)$ is correct: Thyroxine plays a major role in the regulation of the Basal Metabolic Rate $(BMR)$ by stimulating the consumption of oxygen and the production of heat.Statement $(D)$ is incorrect: Hypersecretion of thyroxine (hyperthyroidism) leads to conditions like Graves' disease,which is an autoimmune disorder,but it does not directly cause immunodeficiency.Thus,statements $(A)$,$(B)$,and $(C)$ are correct. The total number of correct statements is $3$.
