1. Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.

• A. a burst of motor activity
• B. a period of sleep
• C. a rise in Liz's heart rate
• D. a drop in Liz's body temperature

Correct answer: A

Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.

2. During prenatal development, the ectoderm becomes the __________.

• A. muscles and skeleton
• B. nervous system and skin
• C. circulatory system and other internal organs
• D. digestive system, lungs, urinary tract, and glands

Correct answer: B

Rationale: The correct answer is B: nervous system and skin. The nervous system, which includes the brain, spinal cord, and nerves, as well as the skin, develop from the ectoderm layer of cells during prenatal development. Choice A is incorrect because muscles and skeleton develop from mesoderm. Choice C is incorrect because the circulatory system and other internal organs develop from mesoderm and endoderm. Choice D is incorrect because the digestive system, lungs, urinary tract, and glands develop from endoderm.

3. People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to __________ influences.

• A. age-graded
• B. history-graded
• C. nonnormative
• D. bio-historical Answer: B Page Ref: 9‒10 Skill Level: Remember Topic: The Lifespan Perspective: A Balanced Point of View Difficulty Level: Easy

Correct answer: B

Rationale: People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to history-graded influences. These influences refer to the events and conditions that are common to a particular historical era and can significantly shape the development and experiences of individuals who live through them. The post-World War II era, economic prosperity, and social changes during the baby boom period are examples of historical events that have had a lasting impact on this generation.

4. The information-processing approach views the human mind as a __________.

• A. socially mediated process
• B. collection of stimuli and responses
• C. system of genetically programmed behaviors
• D. symbol-manipulating system through which information flows

Correct answer: D

Rationale: The information-processing approach views the human mind as a symbol-manipulating system through which information flows. This perspective emphasizes how information is received, processed, stored, and retrieved in the mind, similar to how a computer processes data through symbols and operations. Choices A, B, and C are incorrect because they do not align with the fundamental principles of the information-processing approach, which focuses on the mind's symbolic manipulation of information rather than being a socially mediated process, a collection of stimuli and responses, or a system of genetically programmed behaviors.

5. Lanugo ________.

• A. permits food and oxygen to reach the organism
• B. provides the fetus a cushion against jolts caused by the mother's movements
• C. helps regulate the fetus's body temperature
• D. helps the vernix stick to the skin

Correct answer: D

Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.
