Human Growth and Development Final Exam
1. Which state of arousal is considered the most fleeting?
- A. Regular sleep
- B. REM sleep
- C. Drowsiness
- D. Quiet alertness
Correct answer: D
Rationale: Quiet alertness is indeed the most fleeting state of arousal. This state is characterized by a newborn infant being awake, calm, and attentive, but it is short-lived and transitions quickly to other states of arousal. Regular sleep, REM sleep, and drowsiness are not considered as brief and transitional as quiet alertness in newborn infants.
2. The harm done by teratogens __________.
- A. is straightforward and predictable
- B. is usually apparent at birth
- C. rarely goes beyond physical damage
- D. depends on age at the time of exposure
Correct answer: D
Rationale: The harm done by teratogens depends on the age at the time of exposure. This means that the effects may vary depending on the developmental stage of the fetus when exposed to the teratogen. Teratogens can have different impacts at different stages of pregnancy, leading to a range of potential outcomes in terms of physical and/or cognitive development. Choices A, B, and C are incorrect because the harm caused by teratogens is not straightforward, may not be apparent at birth, and can go beyond physical damage, affecting cognitive development as well.
3. Lily weighed 8 pounds and was 21 inches long at birth. She was __________ than the average baby.
- A. heavier but shorter
- B. heavier and longer
- C. lighter but longer
- D. lighter and shorter
Correct answer: B
Rationale: Lily weighed 8 pounds and was 21 inches long at birth. Being both heavier and longer than average babies typically are at birth, Lily would be considered heavier and longer compared to the average baby. This makes choice B, 'heavier and longer,' the correct answer. Choices A, C, and D are incorrect because Lily was not shorter or lighter than the average baby at birth.
4. Piaget's _________ stage is the most complex period of development.
- A. sensorimotor
- B. preoperational
- C. concrete operational
- D. formal operational
Correct answer: D
Rationale: The formal operational stage in Piaget's theory is characterized by abstract reasoning, hypothetical thinking, and logical reasoning. This stage represents the most complex period of cognitive development according to Piaget. Choices A, B, and C refer to earlier stages in Piaget's theory and do not involve the level of abstract thinking and logical reasoning seen in the formal operational stage.
5. 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.
