1. __________ 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.

2. 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.

3. By using which method of assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups?

• A. sequential
• B. random
• C. systematic
• D. correlational

Correct answer: B

Rationale: By using random assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups. Random assignment helps reduce the likelihood of bias in the selection process and ensures that any differences between groups are due to the treatment and not pre-existing group differences. Sequential, systematic, and correlational assignment methods do not provide the same level of assurance in distributing participants' characteristics equally across treatment groups.

4. __________ children are at risk for poor school performance, substance abuse, and antisocial behavior in adolescence and criminality in adulthood.

• A. Average
• B. Controversial
• C. Rejected
• D. Popular

Correct answer: C

Rationale: Rejected children often face social difficulties that lead to negative outcomes later in life, including academic and behavioral problems. The term 'rejected' specifically refers to children who are socially excluded or shunned by their peers, leading to the mentioned negative consequences. 'Average,' 'Controversial,' and 'Popular' do not convey the same meaning and are not related to the risks mentioned in the question.

5. Baby Gabriella claps her hands after her mother does. Gabriella is displaying __________.

• A. reinforcement
• B. classical conditioning
• C. observational learning
• D. adaptation

Correct answer: C

Rationale: Observational learning is when an individual learns by watching others and mimicking their actions or behaviors. In this scenario, Baby Gabriella claps her hands after her mother does, indicating she is learning through observing her mother's behavior and imitating it. The other choices are incorrect: Reinforcement typically involves a consequence that strengthens a behavior, classical conditioning is a type of learning where an association is made between two stimuli, and adaptation refers to the process of adjusting to new conditions.
