1. What is one role of the hormone estrogen?

• A. Stimulates the development of the milk-producing tissue.
• B. Stimulates the production of lactoferrin.
• C. Stimulates the development of the nipple and duct system in the breast.
• D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.

2. 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.

3. How does human sperm move?

• A. Flagella
• B. Cilia
• C. Neutrophils
• D. None of the above

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.

4. What is the leading cause of maternal mortality?

• A. Pre-eclampsia
• B. Haemorrhage
• C. Sepsis
• D. Obstructed labour

Correct answer: B

Rationale: The correct answer is B: Haemorrhage. Haemorrhage is a leading cause of maternal mortality due to excessive bleeding during childbirth. While conditions like pre-eclampsia, sepsis, and obstructed labor can also be serious complications during pregnancy and childbirth, they are not the primary cause of maternal mortality worldwide.

5. Which of the following is not a barrier method of birth control?

• A. Vaults
• B. Diaphragms
• C. Sterilization
• D. Cervical caps

Correct answer: C

Rationale: The correct answer is C, Sterilization. Sterilization is a permanent form of birth control that involves surgical procedures to prevent pregnancy by blocking the fallopian tubes or vas deferens. Barrier methods physically prevent sperm from reaching the egg, such as vaults, diaphragms, and cervical caps. These devices create a barrier to sperm, unlike sterilization. Therefore, choices A, B, and D are all considered barrier methods of birth control.
