Human Growth and Development Exam Questions Questions
Question 1 of 5
Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.
Correct Answer: A
Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health.
Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.
Question 2 of 5
Which statement about the newborn baby's appearance is true?
Correct Answer: C
Rationale: The correct statement about the newborn baby's appearance is that the trunk is large in comparison to the head, and the legs are straight. This is a common characteristic of newborn babies as their proportions are different from adults.
Choice A is incorrect as there is no consistent trend of girls being longer and heavier than boys at birth.
Choice B is incorrect as the perception of adults wanting to pick up babies is subjective and not a universal truth.
Choice D is incorrect as the average length and weight provided may not apply to all newborn babies, as there can be variations.
Question 3 of 5
Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.
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.
Question 4 of 5
Although Justin spent his first 18 months in an orphanage, his adoptive mother believes that sensitive caregiving will help Justin overcome his early experiences. Justin's mother emphasizes the role of __________ in development.
Correct Answer: A
Rationale: The correct answer is A, nurture. Nurture refers to the environmental influences that shape behavior and development. In this scenario, Justin's adoptive mother believes that providing sensitive caregiving will override the negative effects of his early experiences in the orphanage, highlighting the importance of nurture in promoting healthy development.
Choice B, stages, is incorrect as it refers to the sequence of developmental milestones individuals pass through.
Choice C, stability, is incorrect as it pertains to the consistency of behavior or development over time.
Choice D, nature, is incorrect as it relates to genetic and biological factors influencing development, which is not the focus of Justin's mother's beliefs.
Question 5 of 5
If pregnancy does not occur, the corpus luteum shrinks, and the __________.
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.
