Choose the CORRECT match. Animals Fertilization Embryonic development
- A. Dog Internal Oviparity
- B. Duck External Viviparity
- C. Frog External Oviparity
- D. Cat Internal Ovoviviparity
Correct Answer: C
Rationale: The correct match is C: Frog - External Oviparity. Frogs lay eggs externally, and their fertilization and embryonic development occur outside the female's body. This is characteristic of oviparous animals. The other choices are incorrect because:
A: Dog - Internal Oviparity, dogs give birth to live young and do not lay eggs.
B: Duck - External Viviparity, ducks also give birth to live young and do not lay eggs externally.
D: Cat - Internal Ovoviviparity, cats give birth to live young but retain eggs inside their body until they hatch.
If a woman has a tumor secreting large amounts of estrogen from the adrenal gland, which of the following will occur?
- A. Progesterone levels in the blood will be very low
- B. Her luteinizing hormone secretion rate will be totally suppressed
- C. She will not have normal menstrual cycles
- D. Her bones will be normally calcified
Correct Answer: B
Rationale: Correct Answer: B - Her luteinizing hormone secretion rate will be totally suppressed
Rationale:
1. The tumor secretes large amounts of estrogen, which can lead to negative feedback on the hypothalamus and pituitary gland.
2. Luteinizing hormone (LH) is crucial for ovulation and normal menstrual cycles.
3. High estrogen levels can suppress LH secretion, disrupting ovulation and menstrual cycles.
Summary of other choices:
A: Progesterone levels may actually be elevated due to the tumor-induced high estrogen levels.
C: The disruption of LH secretion can lead to abnormal menstrual cycles.
D: High estrogen levels can lead to bone loss due to inhibition of bone formation and increased bone resorption.
Cowper's gland is another name for:
- A. Prostate gland
- B. Testes
- C. Bulbourethral glands
- D. Preputial glands
Correct Answer: C
Rationale: The correct answer is C: Bulbourethral glands. Cowper's gland is another name for the bulbourethral glands, which are responsible for producing a lubricating fluid that helps neutralize acidity in the urethra before ejaculation. The prostate gland (A) is responsible for producing seminal fluid, the testes (B) are responsible for producing sperm, and the preputial glands (D) are glands found in the foreskin of the penis. Therefore, the bulbourethral glands (C) are the correct answer because they align with the function and location of Cowper's gland.
Estrogen is required for normal reproductive function in the male. Where is the principal site of estrogen synthesis in the male?
- A. Leydig cells
- B. Osteoblasts
- C. Liver cells
- D. Prostate cells
Correct Answer: C
Rationale: Rationale:
1. The correct answer is C: Liver cells. The liver is the principal site of estrogen synthesis in the male.
2. Liver cells contain the enzyme aromatase, which converts androgens into estrogens.
3. Estrogen plays a crucial role in maintaining normal reproductive function in males.
4. Leydig cells (Choice A) are responsible for testosterone production, not estrogen synthesis.
5. Osteoblasts (Choice B) are bone cells involved in bone formation, not estrogen synthesis.
6. Prostate cells (Choice D) are involved in prostate function, not estrogen synthesis.
