How do contraceptive oral pills help in birth control?

Correct Answer: A

Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.

Correct Answer: C

Rationale: The correct expansion for MTP is Medical Termination of Pregnancy. This term is commonly used in healthcare to refer to the procedure of ending a pregnancy. Choices A, B, and D are incorrect because they do not accurately represent the expansion of the abbreviation MTP. Choice A refers to labor induction, choice B is related to plant reproduction, and choice D deals with the transmission of pathogens from mother to offspring.

Correct Answer: D

Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.

Correct Answer: C

Rationale: Amniocentesis is a prenatal test that involves examining chromosomes in the amniotic fluid to detect genetic abnormalities. Therefore, the correct answer is 'Chromosomes.' The other choices, such as 'Fingers,' 'DNA,' and 'Proteins,' do not accurately represent what is analyzed during an amniocentesis procedure and are unrelated to the genetic information obtained through this test.
