1. If pregnancy does not occur, the corpus luteum shrinks, and the __________.

• A. cells begin to duplicate
• B. one-celled zygote multiplies and forms a blastocyst
• C. germinal period lasts only about two weeks
• D. lining of the uterus is discarded

Correct answer: D

Rationale: If pregnancy does not occur, the corpus luteum will shrink. As a result, the lining of the uterus is discarded through the process of menstruation. This shedding of the uterine lining is what causes menstrual bleeding. Choices A, B, and C are incorrect because they do not describe the physiological response of the body when pregnancy does not occur. The corpus luteum shrinking and the subsequent shedding of the uterine lining are part of the menstrual cycle, not processes related to cell duplication, zygote multiplication, or the duration of the germinal period.

2. Two-year-old Eva's parents meet her assertions of independence with tolerance and understanding. They provide suitable guidance and reassurance. According to Erikson's theory, Eva will develop __________ as a result.

• A. basic trust
• B. mistrust
• C. autonomy
• D. industry

Correct answer: C

Rationale: According to Erikson's theory of psychosocial development, when parents support a child's growing independence with guidance and reassurance, the child develops a sense of autonomy. Autonomy is characterized by a growing sense of self-control, confidence, and independence. Basic trust (choice A) is associated with the first stage of Erikson's theory (trust vs. mistrust) during infancy. Mistrust (choice B) arises when a child's basic needs are not met consistently, leading to a lack of trust in the world. Industry (choice D) is related to Erikson's later stages of development and involves competence and productivity in work and tasks.

3. Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.

• A. a burst of motor activity
• B. a period of sleep
• C. a rise in Liz's heart rate
• D. a drop in Liz's body temperature

Correct answer: A

Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.

4. According to the lifespan perspective, _______ is supreme in its impact on the life course.

• A. the prenatal period
• B. early childhood
• C. adolescence
• D. no age period

Correct answer: D

Rationale: According to the lifespan perspective, no single period is considered supreme in its impact on the life course. Each stage of life, from prenatal period through adulthood, plays a significant role in shaping an individual's development. Therefore, the correct answer is 'D: no age period.' Choices A, B, and C are incorrect because the lifespan perspective emphasizes that all stages are important and contribute uniquely to an individual's life course.

5. During prenatal development, the ectoderm folds over to form the __________, or primitive spinal cord.

• A. mesoderm; neuron tract
• B. neural tube
• C. endoderm; neural tube
• D. neuron tract

Correct answer: B

Rationale: The correct answer is B. During prenatal development, the ectoderm folds over to form the neural tube, which eventually develops into the brain and spinal cord. The neural tube is the precursor to the central nervous system, including the primitive spinal cord. Choices A, C, and D are incorrect because the mesoderm does not form the neural tube, the endoderm is not involved in the formation of the central nervous system, and neuron tract is not the structure that forms the primitive spinal cord.
