To address the question, let's evaluate the given assertion (A) and reason (R):
Assertion A: Amniocentesis for sex determination is one of the strategies of Reproductive and Child Health Care Programme.
Reason R: Ban on amniocentesis checks increasing menace of female foeticide.
Analysis:
Conclusion: Given the above analysis, A is false but R is true. Therefore, the correct answer is: A is false but R is true.
Amniocentesis is a diagnostic procedure or a prenatal test to check any chromosomal abnormalities or determine the sex of an unborn child.
Therefore, the correct answer is (C): A is false but R is true.
Student to attempt either option-(A) or (B):
(A) Study the given diagram showing the sectional view of a seminiferous tubule.
Answer the following questions:
OR
(B) Study the figures given below showing initial stages in the formation of female gametophyte and answer the questions that follow.
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
