Primary spermatogonium undergo:
- A. two mitotic divisions to become a secondary spermatocyte
- B. mitosis and then meiosis to become a secondary spermatocyte
- C. two meiotic divisions to become a secondary spermatocyte
- D. meiosis and differentiation to become a secondary spermatocyte
Correct Answer: B
Rationale: The correct answer is B. Primary spermatogonium undergo mitosis to replicate and maintain the diploid chromosome number, then meiosis to reduce the chromosome number, resulting in secondary spermatocytes. Choice A is incorrect as it skips meiosis. Choice C is incorrect as it suggests two meiotic divisions from primary spermatogonium, which is not accurate. Choice D is incorrect because it fails to mention the initial step of mitosis before meiosis in the process.

Choose the correct statements:
- A. every month, a secondary follicle becomes a mature follicle;
- B. the ovary displays a cortical area in which the following are found: lax connective tissue, vessels and nerves.
- C. monthly, beginning with puberty, a mature follicle transforms into a tertiary follicle;
- D. during the female sex life, approximately 400 ovarian follicles become mature;
Correct Answer: B
Rationale: The correct answer is B because the ovary does indeed display a cortical area with lax connective tissue, vessels, and nerves. This area is known as the ovarian cortex. This choice accurately describes the anatomical features present in the ovary.
Choice A is incorrect because not every month does a secondary follicle become a mature follicle. It is a gradual process that occurs over several cycles.
Choice C is incorrect because a mature follicle does not transform into a tertiary follicle monthly starting from puberty. Instead, a mature follicle releases an egg during ovulation.
Choice D is incorrect because the average female has around 400,000 follicles at birth, and only about 400 will become mature and be released during her reproductive years.
What is the function of the milky-colored fluids secreted from the prostate?
- A. Enable sperm to swim
- B. Activate sperm
- C. Cleanse the urethra
- D. Neutralize urine
Correct Answer: C
Rationale: The milky-colored fluid secreted from the prostate cleanses the urethra. This fluid helps neutralize the acidity of the urethra, providing a more suitable environment for sperm to survive. It does not enable sperm to swim or activate them, as these functions are performed by other components of semen. Additionally, it does not neutralize urine, as its primary function is to support sperm survival and motility.
Which bone is called as the shoulder bone
- A. Clavicle
- B. Sternum
- C. Humerus
- D. Scapula
Correct Answer: D
Rationale: The correct answer is D: Scapula. The scapula is commonly known as the shoulder blade and is the bone that connects the upper arm bone (humerus) to the collarbone (clavicle) to form the shoulder joint. The other choices, A: Clavicle, is the collarbone; B: Sternum, is the breastbone; and C: Humerus, is the upper arm bone, are not specifically referred to as the shoulder bone. Therefore, the scapula is the correct answer as it is directly associated with the shoulder joint.
The ________ is an ovoviviparous animal.
- A. Basking shark
- B. Bonobo
- C. Blue shark
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Basking shark. Ovoviviparous animals are those that produce eggs that hatch inside the mother's body, giving birth to live young. Basking sharks exhibit this reproductive strategy, making them ovoviviparous.
Explanation of incorrect choices:
B: Bonobos are primates and give birth to live young, but they are not ovoviviparous.
C: Blue sharks give birth to live young as well, but they are not ovoviviparous.
D: "None of the above" is incorrect as the basking shark is indeed an ovoviviparous animal, making it the correct answer.
