Which individual is most likely to experience the greatest percentage of REM sleep?
- A. Sammy, a preschool child
- B. Jake, a full-term newborn
- C. Sarah, a teenager
- D. Cheryl, a preterm newborn
Correct Answer: D
Rationale: Preterm newborns, like Cheryl, experience a higher percentage of REM sleep compared to full-term newborns. This is because REM sleep plays a critical role in brain development, and preterm infants have an increased need for brain development due to their early arrival. Therefore, Cheryl, as a preterm newborn, is most likely to experience the greatest percentage of REM sleep among the individuals listed.

- B. environmental, but not personal, contexts shape development
- C. development occurs in a neat, orderly sequence of stages unaffected by distinct contexts
- D. people not only are affected by but also contribute to the contexts in which they develop
Correct Answer: D
Rationale: The correct answer is D because the statement aligns with the concept of reciprocal influences in human development. The new evidence suggests that individuals are not only influenced by the contexts in which they develop but also contribute to shaping those contexts. This idea highlights the dynamic and interactive nature of human development, emphasizing the bidirectional relationship between individuals and their environments.

- C. produces blood cells until the organs are mature enough to take over this function
- D. contains one large vein that delivers blood loaded with nutrients and two arteries that remove waste
Correct Answer: C
Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.
