Growth and Development Exam
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. A theory of development __________.
- A. illustrates the ultimate truth about human behavior
- B. describes, explains, and predicts behavior
- C. explains all aspects of human growth
- D. does not require scientific verification
Correct answer: B
Rationale: A theory of development describes, explains, and predicts behavior. It provides a framework for understanding how individuals grow and change over time. The purpose of a theory is not to illustrate ultimate truth or explain all aspects of human growth, but rather to help researchers and practitioners make sense of and predict human behavior. Theories are expected to be tested and refined through scientific verification. Choice A is incorrect because theories do not necessarily illustrate ultimate truth. Choice C is incorrect as theories focus on behavior and development, not all aspects of human growth. Choice D is incorrect because scientific verification is essential for theories to be valid and reliable.
3. In the __________ period, teratogens rarely have any impact.
- A. germinal
- B. embryonic
- C. fetal
- D. prenatal
Correct answer: A
Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.
4. When the blastocyst burrows deep into the uterine lining, __________.
- A. implantation occurs
- B. pregnancy does not occur
- C. it stops growing
- D. the cells of the zygote first duplicate
Correct answer: A
Rationale: When the blastocyst burrows deep into the uterine lining, this process is known as implantation. Implantation is a crucial step in the early stages of pregnancy where the blastocyst attaches to the uterine wall in order to receive nourishment and continue developing. Choice B is incorrect because implantation is a necessary step for pregnancy to occur. Choice C is incorrect as implantation marks the beginning of further growth and development. Choice D is incorrect as the duplication of cells occurs during earlier stages of development, not during implantation.
5. Ethnographic research is directed toward understanding a culture through __________ observation.
- A. naturalistic
- B. participant
- C. systematic
- D. structured
Correct answer: B
Rationale: Ethnographic research is directed toward understanding a culture through participant observation. This type of observation involves the researcher immersing themselves in the culture being studied, actively participating in the daily activities and interactions of the group being studied. Through participant observation, researchers can gain a deep and nuanced understanding of the culture from the inside. Choice A, naturalistic observation, typically refers to observing subjects in their natural environment without interference, but it does not involve actively participating in the culture. Choice C, systematic observation, focuses on carefully planned and structured data collection methods but may not involve direct participation. Choice D, structured observation, implies a predefined set of guidelines for observation but lacks the immersive aspect of participant observation.
