1. The embryonic disk __________.

• A. becomes the new organism
• B. is the outer ring of cells on a blastocyst
• C. has a good chance of survival outside the womb
• D. is a protective membrane that surrounds the amnion Answer: A Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: A

Rationale: The embryonic disk becomes the new organism. It is a cluster of cells within the blastocyst that will develop into the fetus during the early stages of prenatal development. This cluster of cells is responsible for giving rise to all the tissues and organs of the developing organism.

2. What is one challenge associated with longitudinal research?

• A. It does not allow for inferences about cause-and-effect relationships.
• B. Participants may relocate or drop out of the study.
• C. Findings may not be applicable to real-world scenarios.
• D. It does not allow for the examination of individual developmental patterns.

Correct answer: B

Rationale: One challenge associated with longitudinal research is that participants may relocate or drop out of the study over time. This can result in missing data and potential biases in the findings, impacting the study's overall validity and reliability. Furthermore, it can present difficulties for researchers in accurately monitoring and analyzing changes in individuals over an extended period. Options A, C, and D are incorrect because longitudinal research can indeed allow for inferences about cause-and-effect relationships, findings can be generalized to the real world with appropriate design and sampling, and it is suitable for studying individual developmental patterns.

3. In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to __________.

• A. lower birth weight and higher risk of premature birth
• B. suppressed development of the immune system
• C. serious damage to the central nervous system
• D. improved fetal cardiovascular functioning

Correct answer: D

Rationale: In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to improved fetal cardiovascular functioning. Regular exercise has been shown to benefit both the mother and baby by promoting better cardiovascular health and overall well-being during pregnancy. Choices A, B, and C are incorrect as exercise during pregnancy, when done appropriately, does not lead to lower birth weight, higher risk of premature birth, suppressed immune system development, or serious damage to the central nervous system. Instead, it is known to have positive effects on fetal development and maternal health.

4. The harm done by teratogens __________.

• A. is straightforward and predictable
• B. is usually apparent at birth
• C. rarely goes beyond physical damage
• D. depends on age at the time of exposure

Correct answer: D

Rationale: The harm done by teratogens depends on the age at the time of exposure. This means that the effects may vary depending on the developmental stage of the fetus when exposed to the teratogen. Teratogens can have different impacts at different stages of pregnancy, leading to a range of potential outcomes in terms of physical and/or cognitive development. Choices A, B, and C are incorrect because the harm caused by teratogens is not straightforward, may not be apparent at birth, and can go beyond physical damage, affecting cognitive development as well.

5. According to Erikson, the major personality attainment of adolescence is __________.

• A. trust
• B. identity
• C. autonomy
• D. intimacy

Correct answer: B

Rationale: According to Erikson's theory of psychosocial development, the major personality attainment of adolescence is identity. During adolescence, individuals go through a stage called 'Identity vs. Role Confusion,' where they explore different roles and develop a sense of self. Trust (choice A) is associated with the first stage of Erikson's theory, autonomy (choice C) is linked to the toddler stage, and intimacy (choice D) is a key aspect of the young adulthood stage.
