1. Which hormone is primarily responsible for the development of female secondary sexual characteristics?

• A. Progesterone
• B. Testosterone
• C. Estrogen
• D. Oxytocin

Correct answer: C

Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.

2. How do contraceptive oral pills help in birth control?

• A. Preventing ovulation
• B. Killing ova
• C. Killing sperms
• D. More than one of the above

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.

3. What forms the vaginal lining?

• A. Squamous epithelium
• B. Stratified epithelium
• C. Vascular connective tissue
• D. Muscle coat

Correct answer: A

Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.

4. At what age does the first menstrual period typically occur?

• A. 9 and 15 years
• B. 2 and 10 years
• C. 1 and 5 years
• D. 18 and 20 years

Correct answer: A

Rationale: The first menstrual period, known as menarche, typically occurs between the ages of 9 and 15 years. This marks the onset of puberty in females. Choices B, C, and D are incorrect because the first menstrual period does not occur as early as 2 years old, 1 year old, or as late as 18 to 20 years old.

5. What does reproductive health refer to?

• A. Healthy baby
• B. Frequent coitus
• C. Healthy reproductive organs and functions
• D. Longer lifetime

Correct answer: C

Rationale: Reproductive health refers to the overall well-being of the reproductive system, including both the organs and their functions. It encompasses the ability to have a satisfying and safe sex life, the capability to reproduce, and the absence of reproductive problems. Choice A is incorrect because reproductive health is not solely about having a healthy baby but also includes the health of the individual. Choice B is incorrect as it focuses only on sexual activity frequency rather than the holistic well-being of the reproductive system. Choice D is incorrect because a longer lifetime does not specifically relate to reproductive health.
