1. Which part of the neuron receives signals from other neurons?
- A. Axon
- B. Dendrite
- C. Synapse
- D. Myelin sheath
Correct answer: B
Rationale: The correct answer is B, Dendrite. Dendrites are the part of the neuron that receive signals from other neurons and transmit them to the cell body. Axons transmit signals away from the cell body, synapse is the junction between neurons where neurotransmitters are released, and myelin sheath is a fatty layer that insulates and speeds up signal conduction along the axon. Therefore, choices A, C, and D are incorrect in the context of receiving signals from other neurons.
2. Based on the language in the passage, which one of the following scenarios is correct?
- A. The writer is a professional in a business environment.
- B. The writer is a researcher writing for a scientific journal.
- C. The writer is a student writing a first draft of a paper.
- D. The writer is an author of literature.
Correct answer: D
Rationale: The correct answer is D. The passage's descriptive and narrative style, focusing on character and setting details, suggests that the writer is an author of literature. Choice A is incorrect because there is no indication of a business environment or professional context in the passage. Choice B is incorrect as the passage does not align with the technical or formal language typical of scientific journals. Choice C is incorrect as the passage does not reflect the style or content common in student papers, which are usually more structured and formal.
3. Which of the following sentences uses second person point of view?
- A. I don't want to make plans for the weekend before I see my work schedule.
- B. She had to miss the last three yoga classes due to illness.
- C. Pluto is no longer considered a planet because it is not gravitationally dominant.
- D. Be sure to turn off all of the lights before locking up for the night.
Correct answer: D
Rationale: The correct answer is D. This sentence uses the second person point of view by directly addressing the reader or listener with the phrase 'Be sure to.' It is instructing or advising someone on what action to take, making it a clear example of second person point of view. Choices A, B, and C all use first person (I) or third person (she, Pluto), which do not involve direct interaction with the reader or listener, unlike the second person point of view present in choice D.
4. How do you convert yards to feet, and feet to yards?
- A. Multiply yards by 3 to get feet; divide feet by 3 to get yards
- B. Multiply yards by 2 to get feet; divide feet by 2 to get yards
- C. Multiply yards by 1.5 to get feet; divide feet by 1.5 to get yards
- D. Multiply yards by 4 to get feet; divide feet by 4 to get yards
Correct answer: A
Rationale: To convert yards to feet, you need to know that 1 yard is equal to 3 feet. Therefore, to convert yards to feet, you multiply the number of yards by 3. To convert feet to yards, you divide the number of feet by 3. Choice A correctly states that you should multiply yards by 3 to get feet and divide feet by 3 to get yards. Choices B, C, and D provide incorrect conversion factors, leading to inaccurate results.
5. What function do genes serve in the relationship between parents and offspring?
- A. Genes enable hereditary information to be passed from parents to offspring.
- B. Genes prohibit hereditary information from being passed from parents to offspring.
- C. Genes enable environmental factors to affect parents and offspring.
- D. Genes serve no function in the relationship between parents and offspring.
Correct answer: A
Rationale: Genes play a crucial role in passing hereditary information from parents to offspring, ensuring the transmission of genetic traits. This process forms the basis of inheritance and genetic continuity between generations. Choice B is incorrect as genes do not prohibit but rather facilitate the transmission of hereditary information. Choice C is incorrect because genes primarily transmit genetic information, while the influence of environmental factors is separate. Choice D is incorrect as genes are fundamental in genetic inheritance and the relationship between parents and offspring.
