Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : During pregnancy the level of thyroxine is increased in the maternal blood.
Reason (R) : Pregnancy is characterised by metabolic changes in the mother.
In the light of the above statements, choose the most appropriate answer from the options given below:
Both (A) and (R) are correct and (R) is the correct explanation of $(\mathrm{A})$
Both (A) and (R) are correct but (R) is not the correct explanation of $(\mathrm{A})$
(A) is correct but (R) is not correct
(A) is not correct but (R) is correct
Solution
During pregnancy, thyroxine level increases in material blood because metabolic rate in body increases during pregnency. As thyroxine maintain Basal Metabolic rate (BMR) to generate heat.
