Human Growth and Development Exam Questions

1. If pregnancy does not occur, the corpus luteum shrinks, and the __________.

A. cells begin to duplicate
B. one-celled zygote multiplies and forms a blastocyst
C. germinal period lasts only about two weeks
D. lining of the uterus is discarded

Correct answer: D

Rationale: If pregnancy does not occur, the corpus luteum will shrink. As a result, the lining of the uterus is discarded through the process of menstruation. This shedding of the uterine lining is what causes menstrual bleeding. Choices A, B, and C are incorrect because they do not describe the physiological response of the body when pregnancy does not occur. The corpus luteum shrinking and the subsequent shedding of the uterine lining are part of the menstrual cycle, not processes related to cell duplication, zygote multiplication, or the duration of the germinal period.

2. Developmental science is __________ because it has grown through the combined efforts of people from many fields of study.

A. interdisciplinary
B. empirical
C. applied
D. theoretical

Correct answer: A

Rationale: Correct answer: Developmental science is interdisciplinary because it integrates knowledge from multiple fields like psychology, biology, and sociology. The term 'empirical' refers to information gained from observation or experimentation, which is not the focus of this question. 'Applied' and 'theoretical' do not capture the essence of developmental science requiring inputs from various disciplines.

3. Babies who spend more time alert are likely to have __________.

A. parents who feel incompetent
B. a slight advantage in mental development
C. a big disadvantage in social development
D. parents who must exert great effort to soothe them

Correct answer: B

Rationale: Babies who spend more time alert are likely to have a slight advantage in mental development. Being alert allows babies to engage with their surroundings, explore, and learn, which can contribute to their cognitive development. This is different from social development, which is more related to interactions with others, and not necessarily impacted by the amount of alertness a baby displays. Choices A, C, and D are incorrect because there is no direct correlation between a baby's alertness and their parents' feelings of incompetence, a big disadvantage in social development, or the effort parents need to soothe them.

4. According to ecological systems theory, interactions between Marina and her child, Tyler, occur in the __________. Copyright Ãƒâ€šÃ‚Â© 2018 Laura E. Berk. All Rights Reserved. 20 Test Bank for Berk, Development Through the Lifespan, 7e

A. microsystem
B. mesosystem
C. exosystem
D. macrosystem Answer: A Page Ref: 23 Skill Level: Apply Topic: Recent Theoretical Perspectives Difficulty Level: Moderate

Correct answer: A

Rationale: According to ecological systems theory, interactions between Marina and her child, Tyler, occur in the microsystem. The microsystem refers to the immediate social context in which an individual lives, such as interactions with family members, friends, and teachers. Marina and Tyler's interactions within their family unit would be considered part of the microsystem.

5. During the second month of pregnancy, __________.

A. the umbilical cord first appears as a primitive body stalk
B. touch sensitivity extends to most of the body
C. the heart develops separate chambers
D. the heartbeat can be heard through a stethoscope

Correct answer: C

Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.
