1. Which of the following are the two major zones of the respiratory system?
- A. left bronchus and right bronchus
- B. nose and mouth
- C. larynx and pharynx
- D. conducting and respiratory
Correct answer: D
Rationale: The two major zones of the respiratory system are the conducting zone and the respiratory zone. The conducting zone encompasses structures like the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles, which serve to transport air into the lungs. On the other hand, the respiratory zone includes the respiratory bronchioles, alveolar ducts, and alveoli, where the crucial gas exchange process between the air in the lungs and the blood occurs. Choices A, B, and C are incorrect as they do not represent the major zones of the respiratory system but rather individual structures within the system.
2. Which of the following describes a situation in which research results are consistent with every subsequent experiment, but the test used in the experiment does not measure what it claims to measure?
- A. reliable, but not valid
- B. valid, but not reliable
- C. neither reliable nor valid
- D. both reliable and valid
Correct answer: A
Rationale: The correct answer is A, 'reliable, but not valid.' In this scenario, the research results are consistent in every subsequent experiment, indicating reliability. However, the test used does not measure what it claims to measure, leading to a lack of validity in the results. Choice B, 'valid, but not reliable,' would imply that the test consistently measures what it claims but the results are not consistent, which is not the case here. Choice C, 'neither reliable nor valid,' would suggest that the results are neither consistent nor relevant, which does not align with the provided scenario. Choice D, 'both reliable and valid,' would mean that the results are consistent and measure what they claim to measure, which contradicts the situation described in the question.
3. An FBI agent has spent her career studying individual serial killers. From this data, she creates a theory about the traits of these killers. What type of reasoning has she used?
- A. Deductive Reasoning
- B. Conductive Reasoning
- C. Quantitative Reasoning
- D. Inductive Reasoning
Correct answer: D
Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing a general conclusion from specific observations or data, which fits the scenario described where the FBI agent has studied individual serial killers and formulated a theory about their traits based on this specific data. Deductive reasoning (choice A) starts with general information and applies it to a specific case, which is not the case here. Conductive reasoning (choice B) and quantitative reasoning (choice C) are not relevant to the scenario provided.
4. Which hormone stimulates the release of pancreatic enzymes and bile?
- A. Gastrin
- B. Insulin
- C. Cholecystokinin (CCK)
- D. Glucagon
Correct answer: C
Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone that stimulates the release of pancreatic enzymes and bile. CCK is released by the small intestine in response to the presence of fats and proteins in the duodenum, triggering the release of digestive enzymes and bile to aid in the digestion of fats and proteins. Gastrin (Choice A) primarily stimulates gastric acid secretion, not the release of pancreatic enzymes and bile. Insulin (Choice B) regulates blood sugar levels by promoting glucose uptake. Glucagon (Choice D) raises blood glucose levels by stimulating the breakdown of glycogen in the liver.
5. A pendulum swings back and forth. What type of energy conversion occurs during its motion?
- A. Potential energy to kinetic energy and vice versa
- B. Thermal energy to mechanical energy and vice versa
- C. Chemical energy to electrical energy and vice versa
- D. Nuclear energy to radiant energy and vice versa
Correct answer: A
Rationale: As the pendulum swings back and forth, it undergoes a continuous conversion between potential energy (at the highest point of the swing) and kinetic energy (at the lowest point of the swing). At the highest point, the pendulum has maximum potential energy due to its height above the ground. As it swings down, this potential energy is converted into kinetic energy, which is the energy of motion. At the lowest point of the swing, the pendulum has maximum kinetic energy and minimal potential energy. The process repeats as the pendulum swings back in the opposite direction, demonstrating the conversion between potential and kinetic energy. Choices B, C, and D are incorrect because the energy conversion in a swinging pendulum primarily involves changes between potential and kinetic energy, not thermal, chemical, electrical, nuclear, or radiant energy.
