Human Growth and Development Final Exam Answers
1. __________ emerges early prenatally and is well-developed at birth.
- A. Visual acuity
- B. Color vision
- C. Depth perception
- D. Sensitivity to touch
Correct answer: D
Rationale: Sensitivity to touch emerges early prenatally and is well-developed at birth. Newborn babies have a well-developed sense of touch, which is crucial for bonding with their caregivers and exploring their environment. This sensitivity to touch helps babies respond to comforting sensations such as gentle strokes and cuddles. Visual acuity, color vision, and depth perception are sensory capabilities that develop and mature after birth, not prenatally. While important for interacting with the environment, they are not as well-developed at birth as sensitivity to touch.
2. To overcome some of the limitations of traditional developmental designs, investigators sometimes use __________ designs, in which they conduct several similar cross-sectional or longitudinal studies.
- A. sequential
- B. experimental
- C. correlational
- D. quasi-experimental Answer: A Page Ref: 36 Skill Level: Remember Topic: Studying Development Difficulty Level: Easy
Correct answer: A
Rationale: Sequential designs involve conducting multiple similar cross-sectional or longitudinal studies to overcome limitations of traditional developmental designs. By combining different types of study designs, researchers can gain a more comprehensive understanding of development over time. This approach allows for more robust conclusions and can help address potential confounding variables that may impact the results.
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. What is the function of the corpus luteum?
- A. is where fertilization usually takes place
- B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
- C. is one of two long, thin structures that lead to the hollow, softly lined uterus
- D. is one of two walnut-sized organs located deep inside a woman's abdomen
Correct answer: B
Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.
5. Charles Darwin's theory of evolution emphasized __________ and __________.
- A. the normative approach; survival of the fittest
- B. noble savages; physical maturation
- C. tabula rasa; natural selection
- D. natural selection; survival of the fittest
Correct answer: D
Rationale: Charles Darwin's theory of evolution emphasized natural selection and survival of the fittest. Natural selection is the process by which organisms with traits that help them survive and reproduce in their environment are more likely to pass on these traits to their offspring. Survival of the fittest refers to the idea that the organisms best adapted to their environment are more likely to survive and reproduce, leading to the gradual evolution of species over time. Both concepts are central to Darwin's theory of evolution. Choices A, B, and C are incorrect as they do not accurately reflect the key principles highlighted by Darwin in his theory of evolution.
