1. How many autosomes does a human primary spermatocyte have?

• A. 34
• B. 44
• C. 54
• D. 33

Correct answer: B

Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.

2. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

3. Septic abortion is characterized by:

• A. Backache.
• B. Os open.
• C. Heavy bleeding.
• D. Maternal pyrexia.

Correct answer: D

Rationale: Septic abortion is characterized by maternal pyrexia. Maternal pyrexia, or fever, is a hallmark sign of septic abortion due to infection. Backache and heavy bleeding can be present in abortion but are not specific to septic abortion. 'Os open' does not directly characterize septic abortion.

4. What is the purpose of Hysterosalpingo-contrast Sonography?

• A. Check a woman's tubes and is done with an X-ray and dye test called a hysterosalpingogram
• B. Detect Human Chorionic Gonadotrophic hormone (HCG) in urine or whole blood.
• C. Diagnose ovarian cancer using MRI technology.
• D. Detect cancer cells in the cervix.

Correct answer: A

Rationale: Hysterosalpingo-contrast Sonography is a test used to check a woman's fallopian tubes with an X-ray and dye test called a hysterosalpingogram. This test is specifically designed to evaluate the patency of the fallopian tubes and the uterine cavity. Choices B, C, and D are incorrect as they do not align with the purpose of Hysterosalpingo-contrast Sonography.

5. Where does fertilization normally occur?

• A. Ampulla
• B. Interstitial portion
• C. Isthmus
• D. Infundibulum

Correct answer: A

Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.
