1. What is the term for a fluid-filled sac in which the baby floats until just before it is born?
- A. Amnion
- B. Placenta
- C. Umbilical cord
- D. Embryo
Correct answer: A
Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.
2. What is the significance of early intervention in preventing mental disorders?
- A. Early intervention has no significant impact on preventing mental disorders.
- B. Early intervention is critical in reducing the risk of developing mental disorders.
- C. Early intervention can sometimes exacerbate mental disorders.
- D. Early intervention is only effective in severe cases.
Correct answer: B
Rationale: Early intervention is crucial in preventing or mitigating the development of mental disorders by addressing issues before they fully develop. Choice A is incorrect because early intervention plays a significant role in preventing mental disorders. Choice C is incorrect as early intervention aims to improve mental health outcomes. Choice D is incorrect as early intervention is effective across various stages of mental health conditions, not just in severe cases.
3. In order for one to have a recessive trait (e.g., having red hair), the person must receive?
- A. At least one copy of a recessive gene from a parent
- B. Two copies of a recessive gene, one from each parent
- C. At least one copy of a recessive gene and at least one copy of a dominant gene
- D. At least two copies of a recessive gene from one parent
Correct answer: B
Rationale: Recessive traits are expressed when an individual inherits two copies of the recessive gene, one from each parent. Therefore, the correct answer is B. Choice A is incorrect as one copy of a recessive gene is not sufficient to display a recessive trait. Choice C is incorrect because having at least one copy of a dominant gene is unrelated to expressing a recessive trait. Choice D is incorrect because two copies of a recessive gene must come from both parents, not just one.
4. Most behavioral disorders are determined primarily by ________.
- A. genetics
- B. upbringing
- C. diet
- D. environment
Correct answer: A
Rationale: Genetics play a significant role in the development of behavioral disorders. While upbringing, diet, and environment can also influence behavior, genetics are often the primary factor in determining behavioral disorders. Choice B (upbringing) can contribute to behavior but is not the sole determinant of behavioral disorders. Choice C (diet) can impact behavior but is not the primary factor in behavioral disorders. Choice D (environment) can also influence behavior, but genetics typically play a more significant role in determining behavioral disorders.
5. Who is credited with establishing psychology as a distinct scientific field, separate from other disciplines?
- A. G. Stanley Hall
- B. René Descartes
- C. William James
- D. Wilhelm Wundt
Correct answer: D
Rationale: Wilhelm Wundt is the correct answer as he is credited with establishing psychology as a distinct scientific field. Wundt founded the first laboratory dedicated to experimental psychology in 1879, which marked the beginning of psychology as a separate discipline. While the other individuals mentioned in the choices have made significant contributions to the field of psychology, Wilhelm Wundt is specifically known for his pioneering work in establishing psychology as a unique and independent discipline.
