What is one of the major issues affecting adolescents in terms of sexual and reproductive health?

Correct Answer: A

Rationale: Limited access to contraceptives and family planning is indeed a major issue affecting adolescents in terms of sexual and reproductive health. This lack of access can lead to unintended pregnancies, sexually transmitted infections, and limited reproductive choices. Choice B, equal representation in decision-making, although important, is not directly related to sexual and reproductive health issues faced by adolescents. Choice C, decreased need for sexual education, is incorrect as proper sexual education is crucial in promoting healthy behaviors and preventing risks. Choice D, equal opportunities for career growth, is also unrelated to the specific issues surrounding sexual and reproductive health in adolescents.

Correct Answer: B

Rationale: In reproductive health, understanding the anatomy and physiology of the male reproductive system is crucial. Bidder's canal, also known as the vas deferens, is a tubular structure that plays a key role in the transport of sperm from the testes to the urethra for ejaculation. Therefore, the correct answer is B) Sperms. Option A) Eggs is incorrect because Bidder's canal is not involved in the transport of eggs in the female reproductive system. Option C) Ammonia is incorrect as Bidder's canal does not receive ammonia. Option D) Oxygenated blood is also incorrect because Bidder's canal is not a part of the circulatory system and does not receive oxygenated blood. Educationally, this question reinforces the importance of knowing the specific functions and structures of the male reproductive system. Understanding the role of Bidder's canal in sperm transport is essential for comprehending male fertility and reproductive health. Students need to grasp these concepts to appreciate the intricacies of human reproduction and potential issues that can arise in this system.

Correct Answer: A

Rationale: In the context of pharmacology, understanding basic reproductive biology is crucial as it can impact drug efficacy and safety in various populations. In this question, the correct answer is A) Goat, which is an example of a viviparous animal. Viviparous animals give birth to live young ones rather than laying eggs. This is important in pharmacology as drug metabolism and potential teratogenic effects can vary between viviparous and oviparous species. Option B) Duck is incorrect as ducks are oviparous, meaning they lay eggs. Understanding the reproductive strategies of different species is important when considering drug effects on embryonic development. Option C) Crocodile is also incorrect as crocodiles are oviparous reptiles that lay eggs. Knowledge of the reproductive modes of different animals helps pharmacologists in assessing the potential impact of drugs on developing embryos. By knowing the reproductive strategies of various animals, pharmacologists can make more informed decisions regarding drug use during pregnancy and understand potential risks to the developing fetus. This knowledge is essential in ensuring the safe use of medications in reproductive health and underscores the importance of understanding basic biology in pharmacological practice.

Correct Answer: C

Rationale: The correct answer is the uterus. The uterus is positioned directly posterior to the bladder in the female reproductive system. The uterine tube (choice A) is also known as the fallopian tube, which is not positioned directly posterior to the bladder. The vagina (choice B) is located below the uterus and not directly posterior to the bladder. The ovaries (choice D) are located on either side of the uterus, but they are not positioned directly posterior to the bladder.

Correct Answer: A

Rationale: The correct answer is A: Oligomenorrhea, obesity, and hirsutism. Polycystic ovarian syndrome (PCOS) commonly presents with irregular periods (oligomenorrhea), obesity, and increased hair growth (hirsutism) due to hormonal imbalances. Choice B is incorrect as amenorrhea (absence of periods), generalized hair loss, and weight gain are not typical features of PCOS. Choice C is incorrect as repeated ectopic pregnancies and chronic pelvic pain are not characteristic of PCOS. Choice D is incorrect as fatigue, body aches, and menorrhagia (excessive menstrual bleeding) are not primary symptoms seen in PCOS.
