1. 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.

2. __________ supplementation early in pregnancy reduces the risk of abnormalities of the neural tube, the circulatory system, and the urinary tract.

• A. Vitamin A
• B. Folic acid
• C. Vitamin D
• D. Vitamin C

Correct answer: B

Rationale: Folic acid supplementation early in pregnancy is crucial as it reduces the risk of abnormalities in the developing fetus. It is specifically known to prevent issues related to the neural tube, circulatory system, and urinary tract. Vitamin A, Vitamin D, and Vitamin C do not play the same role as folic acid in preventing these specific birth defects, making them incorrect choices.

3. 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.

4. The outermost level of Bronfenbrenner's model is the __________.

• A. microsystem
• B. macrosystem
• C. exosystem
• D. mesosystem

Correct answer: B

Rationale: The outermost level of Bronfenbrenner's model is the macrosystem. This level refers to the broader cultural context that shapes the values, laws, customs, and resources of a particular society. It includes factors such as ideology, political systems, societal norms, and cultural influences that impact development at all other levels within the model. Choice A, microsystem, refers to the immediate environment or setting in which an individual lives and interacts. Choice C, exosystem, involves settings that individuals do not directly experience but still influence them. Choice D, mesosystem, refers to the connections between various aspects of an individual's microsystem.

5. In an experiment, the independent variable __________.

• A. is the one the investigator expects to be influenced by another variable
• B. is the one the investigator expects to cause changes in another variable
• C. cannot be manipulated or controlled by the researcher
• D. is the number that describes how two measures are associated with each other

Correct answer: B

Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.
