- A. consciously choose to act responsibly
- B. go to a quiet place and talk about what you are feeling with your partner
- C. explore the feelings and do what feels best
- D. see a doctor
Correct Answer: A
Rationale: The correct answer is A because it emphasizes the importance of consciously choosing to act responsibly when sexual feelings arise. This involves considering the consequences, respecting boundaries, and making informed decisions. Going to a quiet place to talk (B) may not address responsible actions. Exploring feelings and doing what feels best (C) may lead to impulsive or harmful choices. Seeing a doctor (D) is not necessary for regular sexual feelings.

Testosterone is secreted by
- A. Leydig cells.
- B. Sertoli cells.
- C. spermatocytes.
- D. early spermatids.
Correct Answer: A
Rationale: Testosterone is secreted by Leydig cells in the testes. Leydig cells are interstitial cells located between the seminiferous tubules. They are responsible for producing and secreting testosterone, which plays a crucial role in stimulating the development of male secondary sexual characteristics and maintaining male reproductive functions. Sertoli cells provide nourishment and support for developing sperm cells but do not secrete testosterone. Spermatocytes and early spermatids are involved in the process of spermatogenesis and do not secrete testosterone. Therefore, the correct answer is A because Leydig cells are specifically known for their role in testosterone production.
The result of oogenesis is _____.
- A. one secondary oocyte
- B. two secondary oocytes
- C. one ovum
- D. four ootids
Correct Answer: C
Rationale: The correct answer is C: one ovum. During oogenesis, a primary oocyte undergoes meiosis to produce one mature ovum and three polar bodies. The ovum contains the majority of the cytoplasm and organelles needed for fertilization. The other choices are incorrect because:
A: one secondary oocyte - After meiosis I, the primary oocyte develops into one secondary oocyte and one polar body.
B: two secondary oocytes - This is not a possible outcome of oogenesis as only one secondary oocyte is produced.
D: four ootids - Ootids are the immediate products of meiosis II in oogenesis and are not the final mature gametes like the ovum.
Which hormone thickens the lining of the uterus?
- A. FSH
- B. estrogen
- C. LH
- D. progesterone
Correct Answer: B
Rationale: The correct answer is B: estrogen. Estrogen is responsible for thickening the lining of the uterus during the menstrual cycle in preparation for implantation of a fertilized egg. Follicle-stimulating hormone (FSH) stimulates the growth of ovarian follicles. Luteinizing hormone (LH) triggers ovulation. Progesterone helps maintain the uterine lining during the second half of the menstrual cycle. Estrogen plays a key role in the initial thickening of the uterine lining, making it the correct choice.
Which situation would be part of the normal reproductive cycle of a human?
- A. the presence of testosterone regulating gamete production in a male
- B. estrogen in concentrations that would produce sperm in a female
- C. a high progesterone level in a male
- D. a low insulin level in either a male or a female
Correct Answer: A
Rationale: Step 1: Testosterone is a hormone primarily produced by the testes in males, regulating sperm production.
Step 2: Gametes are reproductive cells (sperm in males), crucial for the reproductive cycle.
Step 3: Therefore, the presence of testosterone regulating gamete production in a male is a normal part of the reproductive cycle.
Summary:
- Option B is incorrect as estrogen, a female sex hormone, does not produce sperm.
- Option C is incorrect as progesterone is a hormone mainly involved in the menstrual cycle and pregnancy, not in males.
- Option D is incorrect as insulin is a hormone related to glucose metabolism, not directly involved in the reproductive cycle.
