1. What causes the changes in appearance seen in boys at the time of puberty?

• A. Prolactin
• B. Adrenaline
• C. Estrogen
• D. Testosterone

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

• A. Bleeding per vaginum in early pregnancy
• B. Willingness to terminate pregnancy
• C. Expulsion of products of conception after the 28th week of gestation
• D. Expulsion of products of conception before the 28th week of gestation

Correct answer: D

Rationale: Abortion is defined as the expulsion of products of conception before the 28th week of gestation. Choice A is incorrect as it describes bleeding in early pregnancy, not the definition of abortion. Choice B is incorrect as it refers to the willingness to terminate a pregnancy rather than the actual act of expulsion.

• A. Placenta
• B. Chorion
• C. Endometrium

Rationale: The correct answer is A: Placenta. The placenta is a temporary organ that connects a mammalian mother to its foetus. It plays a crucial role in facilitating the exchange of nutrients, oxygen, and waste between the mother and the developing baby. Choice B, Chorion, is incorrect as it is a part of the fetal membrane but not the organ that connects the mother to the fetus. Choice C, Endometrium, is incorrect as it is the lining of the uterus where implantation occurs but is not the organ responsible for connecting the mother to the fetus. Choice D, None of the above, is incorrect as the placenta specifically fits the description provided in the question.

Choice A, Pelvic floor, refers to the structure supporting the organs in the pelvic cavity, not the space between the vaginal and rectal canals. Choice C, Vestibule, is the space within the labia minora containing the openings of the urethra and vagina, not the area between the vaginal and rectal canals. Choice D, Perineal body, is a fibromuscular mass in the perineum area but not the space between the vaginal and rectal canals.
