Human Growth and Development Final Exam Questions

Question 1 of 5

By the end of Greta's first month of pregnancy, her embryo __________.

Correct Answer: B

Rationale: By the end of Greta's first month of pregnancy, her embryo is about ¼ inch long. During the first month of pregnancy, the embryo is in the very early stages of development, and its size is typically around ¼ inch as it continues to grow and develop in the uterus.

Choices A, C, and D are incorrect because sensory abilities like sensing the world, sucking thumb, and curling toes develop later in the pregnancy as the embryo progresses through different stages of development.

Question 2 of 5

In an experiment, the independent variable __________.

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.

Question 3 of 5

Taking tests and answering questionnaires are examples of __________.

Correct Answer: D

Rationale: Taking tests and answering questionnaires are examples of research methods. Research methods refer to the specific approaches used in conducting research, such as collecting data, analyzing information, and drawing conclusions. In this case, tests and questionnaires are tools used to gather information and data for research purposes, making them examples of research methods.

Choices A, B, and C are incorrect because research designs refer to the overall structure and plan of a study, theories are explanations developed through research and observation, and hypotheses are specific predictions or statements that can be tested through research.

Question 4 of 5

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

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.

Question 5 of 5

Critics worry that fetal monitoring __________.

Correct Answer: C

Rationale: Critics worry that fetal monitoring may identify babies as in danger who, in fact, are not. This can lead to unnecessary interventions and stress for the parents. It is important to carefully consider the accuracy and benefits of fetal monitoring to avoid unnecessary harm to both the mother and the baby.
Choice A is incorrect because fetal monitoring does not cause numbness in the lower half of the body.
Choice B is incorrect as fetal monitoring is helpful in detecting hidden problems with the baby.
Choice D is incorrect as there is no direct link between fetal monitoring and an increased likelihood of infant brain damage.
