Question
Given below are two statements: One is labelled as Assertion (A) and other is labelled as Reason (R). Assertion (A): During menstrual cycle, the ovulation takes place approximately on 14th day. Reason (R): Rapid secretion of LH in the middle of menstrual cycle induces rupture of Graafian follicle and thereby the release of ovum.
In the light of the above statements, choose the most appropriate answer from the options given below.
(A) is True but (R) is False.
(A) is False but (R) is True
Both (A) and (R) are True and (R) is the correct explanation of (A).
Both (A) and (R) are True but (R) is not the correct explanation of (A).
According to the textbook, both LH and FSH attain a peak level in the middle of the cycle (about the 14th day) . This rapid secretion of LH, leading to its maximum level during the mid-cycle (called LH surge), induces the rupture of the Graafian follicle and thereby the release of the ovum (ovulation) . Therefore, the reason correctly explains the cause and timing of the assertion.
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Human Reproduction. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
