1. Which part of the neuron receives signals from other neurons and conducts them toward the cell body?

• A. Axon
• B. Dendrite
• C. Synapse
• D. Myelin sheath

Correct answer: B

Rationale: The dendrites are the part of the neuron that receives signals from other neurons and conducts them toward the cell body. They play a crucial role in gathering incoming signals and transmitting them to the cell body for processing. The axon, on the other hand, is responsible for carrying signals away from the cell body. The synapse is the point of connection between two neurons facilitating communication, while the myelin sheath is a protective layer surrounding the axon that aids in accelerating signal transmission.

2. Based on his work and goals, how should the sentence 'Fred Hampton desired to see lasting social change for African Americans through nonviolent means and community recognition.' be best introduced?

• A. NO CHANGE
• B. Unfortunately,
• C. Finally,
• D. As a result,

Correct answer: D

Rationale: The correct answer is 'D: As a result.' This choice effectively ties Hampton's desire for social change to his ongoing efforts and achievements. 'As a result' indicates a logical connection between Hampton's aspirations and the actions he took to achieve them. Choices B, C, and A are incorrect because they do not provide a suitable transition that connects Hampton's goals with his actions or achievements. 'Unfortunately' (choice B) introduces a negative connotation that is not appropriate in this context. 'Finally' (choice C) suggests a chronological sequence rather than a cause-and-effect relationship. 'NO CHANGE' (choice A) does not establish a clear link between Hampton's desires and his efforts for social change.

3. What is the equivalent of 35.4 centimeters in kilometers (km)?

• A. 0.00354 km
• B. 0.000354 km
• C. 0.00345 km
• D. 0.0345 km

Correct answer: B

Rationale: To convert centimeters to kilometers, you need to divide by 100,000 since there are 100,000 centimeters in a kilometer. Therefore, 35.4 cm ÷ 100,000 = 0.000354 km. Choice A (0.00354 km) is incorrect as it represents dividing by 10,000, not 100,000. Choice C (0.00345 km) is incorrect as the last digit is different from the correct answer. Choice D (0.0345 km) is incorrect as it represents dividing by 1,000, not by 100,000.

4. A researcher is studying the response of bacteria to a certain chemical. In three experiments, the bacteria swim towards the chemical, and in one experiment, the bacteria swim away from it. What would be the most appropriate next step for the researcher?

• A. Report only the first three experiments.
• B. Report all the experiments, but refrain from making any conclusions.
• C. Repeat the experiment several more times and apply a statistical analysis to the data.
• D. Repeat the experiment, adding a new chemical to determine its effect on the bacteria.

Correct answer: C

Rationale: Repeating the experiment multiple times and applying statistical analysis would help ensure the results are reliable. By doing so, the researcher can validate the observed trends and determine the significance of the bacteria's response to the chemical. This approach would enhance the credibility of the findings and allow for more robust conclusions to be drawn. Reporting only the first three experiments (Choice A) would overlook critical data that could provide a comprehensive understanding of the bacteria's response. Refraining from making any conclusions (Choice B) would not utilize the available data effectively. Adding a new chemical in a repeated experiment (Choice D) would deviate from focusing on analyzing the response to the original chemical, introducing unnecessary variables.

5. On which day of the week will they be able to water their lawn?

• A. Tuesday
• B. Wednesday
• C. Thursday
• D. Saturday

Correct answer: B

Rationale: Based on the town's watering schedule, residents with addresses ending in 7 should water their lawns on Wednesdays. The Morgan family's address ends in 7, so they should set up their watering schedule for Wednesdays. Therefore, the correct answer is Wednesday. Choices A, C, and D are incorrect as they correspond to days designated for addresses ending in other numbers according to the town's schedule.
