Human Growth and Development Final Exam Answers
1. __________ increases tenfold from the twentieth week until birth.
- A. Amniotic fluid
- B. Brain weight
- C. Fetal length
- D. Neuron production
Correct answer: B
Rationale: Brain weight increases tenfold from the twentieth week until birth. This rapid growth and development of the brain during the prenatal period is crucial for setting the foundation for future cognitive and neurological functions. Choices A, C, and D are incorrect because although they also undergo changes during prenatal development, none of them increase tenfold from the twentieth week until birth, unlike brain weight.
2. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.
- A. long-lived predatory fish; mercury
- B. freshwater fish; lead
- C. long-lived predatory fish; polychlorinated biphenyls
- D. freshwater fish; radiation
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.
3. The negative outcome of Erikson's midlife stage, stagnation, focuses on __________.
- A. role confusion
- B. selflessness
- C. self-indulgence
- D. guilt and shame
Correct answer: C
Rationale: The correct answer is C: 'self-indulgence'. Stagnation in Erikson's midlife stage refers to a lack of growth and self-indulgence, leading to a feeling of unproductiveness. This contrasts with 'role confusion' (A), which is associated with Erikson's adolescence stage, 'selflessness' (B) which is a positive trait, and 'guilt and shame' (D) which are emotions typically associated with earlier stages of development.
4. By the end of Greta's first month of pregnancy, her embryo __________.
- A. can sense its world
- B. is about ¼ inch long
- C. can suck its thumb
- D. can curl its toes
Correct answer: B
Rationale: By the end of Greta's first month of pregnancy, her embryo is about ¼ inch long. During the first month of pregnancy, the embryo is in the very early stages of development, and its size is typically around ¼ inch as it continues to grow and develop in the uterus. Choices A, C, and D are incorrect because sensory abilities like sensing the world, sucking thumb, and curling toes develop later in the pregnancy as the embryo progresses through different stages of development.
5. According to Erikson, the danger in middle childhood is __________, reflected in the pessimism of children who lack confidence in their ability to do things well.
- A. shame
- B. mistrust
- C. inferiority
- D. despair
Correct answer: C
Rationale: According to Erikson's psychosocial theory, the danger in middle childhood is 'inferiority.' During this stage, children may develop a sense of inadequacy and inferiority if they are unable to master the social and academic tasks expected of them. This feeling of inferiority can lead to low self-esteem and pessimism about their abilities. Choice A, 'shame,' is more closely associated with Erikson's stage of autonomy vs. shame and doubt in early childhood. Choice B, 'mistrust,' is linked to Erikson's stage of trust vs. mistrust in infancy. Choice D, 'despair,' is related to Erikson's stage of integrity vs. despair in late adulthood.
