• C. produces blood cells until the organs are mature enough to take over this function
• D. contains one large vein that delivers blood loaded with nutrients and two arteries that remove waste Answer: C Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

2. The __________ reflex helps a newborn find the nipple.

• A. rooting
• B. Moro
• C. Babinski
• D. tonic neck Answer: A Page Ref: 101 Skill Level: Understand Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate

Correct answer: A

Rationale: The rooting reflex is the correct answer. This reflex helps a newborn baby find the nipple by turning their head and opening their mouth when their cheek is stroked or touched. This is crucial for the baby to locate and latch onto the mother's breast for feeding. The rooting reflex typically disappears around 4 months of age.

3. Taking tests and answering questionnaires are examples of __________.

• A. research designs
• B. theories
• C. hypotheses
• D. research methods

Correct answer: D

Rationale: Taking tests and answering questionnaires are examples of research methods. Research methods refer to the specific approaches used in conducting research, such as collecting data, analyzing information, and drawing conclusions. In this case, tests and questionnaires are tools used to gather information and data for research purposes, making them examples of research methods. Choices A, B, and C are incorrect because research designs refer to the overall structure and plan of a study, theories are explanations developed through research and observation, and hypotheses are specific predictions or statements that can be tested through research.

4. In all societies studied, the most common attachment quality is the __________ pattern.

• A. insecure-avoidant
• B. insecure-resistant
• C. disorganized/disoriented
• D. secure

Correct answer: D

Rationale: The correct answer is D, 'secure.' Research shows that the secure attachment pattern is the most common across various societies. In this pattern, children feel safe, secure, and loved, allowing them to explore the world and seek comfort from their caregivers when needed. Choices A, B, and C are incorrect because while these attachment patterns exist, they are not as prevalent or universal as the secure attachment pattern. Insecure-avoidant attachment involves children avoiding or ignoring their caregiver, insecure-resistant attachment consists of ambivalence and mixed emotions towards the caregiver, and disorganized/disoriented attachment is characterized by inconsistent and often chaotic behaviors towards the caregiver.

5. In the last weeks of pregnancy, __________.

• A. the fetus usually loses weight
• B. most fetuses assume an upside-down position
• C. fetal growth increases dramatically
• D. the fetus relies on its own well-developed immune system

Correct answer: B

Rationale: In the last weeks of pregnancy, most fetuses assume an upside-down position known as the head-down position or vertex presentation. This position is ideal for a smoother labor and delivery process as it helps the baby move through the birth canal. Fetal growth has already slowed down at this stage, so option C is incorrect. Option A is inaccurate as the fetus typically gains weight in the final weeks. Option D is incorrect because the fetus relies on the mother's immune system while in the womb.
