1. Amniocentesis deals with patterns of ______ in the amniotic fluid.

• A. Fingers
• B. DNA
• C. Chromosomes
• D. Proteins

Correct answer: C

Rationale: Amniocentesis is a prenatal test that involves examining chromosomes in the amniotic fluid to detect genetic abnormalities. Therefore, the correct answer is 'Chromosomes.' The other choices, such as 'Fingers,' 'DNA,' and 'Proteins,' do not accurately represent what is analyzed during an amniocentesis procedure and are unrelated to the genetic information obtained through this test.

2. What is the function of luteinizing hormone?

• A. Maintains the corpus luteum
• B. Ripens the Graafian follicle
• C. Prepares the breasts for lactation
• D. Produces regrowth of the endometrium

Correct answer: A

Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.

3. Which family planning method was alternatively provided by the family life movement?

• A. Use of condom
• B. Use of spermicides
• C. Use of natural family planning
• D. Use of hormonal pills

Correct answer: C

Rationale: The family life movement promoted natural family planning as an alternative method. Natural family planning involves tracking a woman's menstrual cycle to determine the fertile period, making it distinct from the other options provided. Condoms (Choice A) and spermicides (Choice B) are barrier methods, while hormonal pills (Choice D) involve the use of synthetic hormones to prevent pregnancy. Therefore, the correct answer is the use of natural family planning.

4. What type of tissue lines the testes?

• A. Glandular tissue.
• B. Squamous epithelium.
• C. Transitional epithelium.
• D. Stratified epithelium.

Correct answer: A

Rationale: The correct answer is A: Glandular tissue. The testes are lined with seminiferous tubules, which contain germ cells and Sertoli cells that are involved in sperm production. These cells are part of the glandular tissue that makes up the testes. Choices B, C, and D are incorrect because squamous, transitional, and stratified epithelium are not typically found lining the testes. Squamous epithelium is a type of epithelial tissue found in areas like the skin, transitional epithelium lines organs like the bladder, and stratified epithelium is present in structures like the skin and esophagus.

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.
