1. Men with even tiny amounts of dioxin in their bloodstream father __________.

• A. nearly twice as many girls as boys
• B. nearly three times as many boys as girls
• C. more twins and triplets than unaffected men
• D. fewer children than unaffected men

Correct answer: A

Rationale: Men with even tiny amounts of dioxin in their bloodstream father nearly twice as many girls as boys. This is due to the impact of dioxin exposure on sperm cells, leading to a skewed ratio of female to male offspring. Choice B is incorrect as the question specifically mentions that men father more girls than boys. Choice C is incorrect as dioxin exposure does not necessarily lead to more twins and triplets. Choice D is incorrect as men with dioxin in their bloodstream father more girls, not fewer children overall.

2. The most rapid prenatal changes take place in the period of the __________.

• A. zygote
• B. blastocyst
• C. embryo
• D. fetus

Correct answer: C

Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.

3. What is the longest stage of labor?

• A. Delivery of the baby
• B. Delivery of the placenta
• C. Dilation and effacement of the cervix
• D. Release of epinephrine and cortisol

Correct answer: C

Rationale: The correct answer is C: Dilation and effacement of the cervix. This stage can last for hours, especially for first-time mothers, as the cervix needs to dilate and efface to allow for the baby's passage through the birth canal. Once the cervix is fully dilated and effaced, the woman can begin pushing during the second stage of labor to deliver the baby. The delivery of the baby itself is usually a shorter process compared to the time taken for the cervix to dilate and efface. Choices A, B, and D are incorrect because they represent other stages within the labor process that come after the dilation and effacement of the cervix.

4. Today, Albert Bandura's theory stresses the importance of __________.

• A. behavior modification
• B. punishment
• C. cognition
• D. reinforcement

Correct answer: C

Rationale: Albert Bandura's theory stresses the importance of cognition. Bandura's Social Learning Theory emphasizes the role of cognitive processes in learning and behavior, including the influence of observation, modeling, and mental representations. This theory highlights how individuals learn through observation and imitation of others, as well as their own thought processes and beliefs. Choices A, B, and D are incorrect because while behavior modification, punishment, and reinforcement are aspects related to learning theories, they are not the primary focus of Bandura's theory, which revolves around cognition and social learning.

5. According to the cognitive perspective of perceptual development, what do babies do?

• A. are blank slates
• B. impose meaning on what they perceive
• C. actively search for discontinuous stimuli
• D. seek variant features in the environment

Correct answer: B

Rationale: According to the cognitive perspective of perceptual development, babies impose meaning on what they perceive. This means that babies actively interpret and make sense of the stimuli they encounter. Choice A is incorrect because babies are not seen as blank slates in this context; they actively engage with their environment. Choice C is incorrect as babies do not necessarily search for discontinuous stimuli, but rather interpret what they perceive. Choice D is incorrect as seeking variant features in the environment is not a core concept of the cognitive perspective of perceptual development.
