1. Which technique is used to detect HIV/AIDS?

A. Northern blot and ELISA
B. Immunoblot and ELISA
C. Western blot and ELISA
D. Southern blot and ELISA

Correct answer: C

Rationale: The correct answer is C: Western blot and ELISA. Western blot and ELISA are commonly used techniques in the detection of HIV/AIDS. Western blot is used to confirm the presence of HIV antibodies in a patient's blood after an initial positive ELISA test. Northern blotting is a technique used for RNA analysis, not for detecting HIV/AIDS (Choice A). Immunoblotting is another term for Western blotting, so Choice B is incorrect. Southern blotting is used for DNA analysis, not for detecting HIV/AIDS (Choice D).

2. What action does the copper used in Copper T have?

A. Blastocidal
B. Bacteriostatic
C. Bacteriocidal
D. Spermicidal

Correct answer: D

Rationale: The correct answer is D, Spermicidal. The copper in Copper T exerts its action by affecting sperm viability and motility, thus preventing fertilization. Choices A, B, and C are incorrect because Copper T primarily works by preventing sperm from reaching and fertilizing the egg, rather than acting on blastocysts, bacteria, or bacteriocins.

3. What is one role of the hormone estrogen?

A. Stimulates the development of the milk-producing tissue.
B. Stimulates the production of lactoferrin.
C. Stimulates the development of the nipple and duct system in the breast.
D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.

4. Which of the following is an example of an oviparous animal?

A. Pigeon
B. Elephant
C. Sheep
D. None of the above

Correct answer: A

Rationale: The correct answer is A: Pigeon. Oviparous animals are those that lay eggs, and pigeons fall under this category. Choice B, Elephant, is incorrect because elephants are viviparous, giving birth to live young. Choice C, Sheep, is also incorrect as sheep are viviparous animals. Choice D, None of the above, is not the correct answer as a pigeon is indeed an example of an oviparous animal.

5. According to the Medical Termination of Pregnancy (MTP) Act, 1971, how many weeks of pregnancy is Medical Termination of Pregnancy considered safe up to?

A. 8 Weeks
B. 12 Weeks
C. 18 Weeks
D. 6 Weeks

Correct answer: B

Rationale: According to the Medical Termination of Pregnancy (MTP) Act, 1971, Medical Termination of Pregnancy is considered safe up to 12 weeks of pregnancy. This timeframe is crucial to ensure the safety and well-being of the individual undergoing the procedure. Choices A, C, and D are incorrect because they do not align with the legal provisions outlined in the MTP Act, 1971.
