1. 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.

2. A symbiotic relationship where one organism benefits and the other is not harmed is called:

• A. Mutualism
• B. Commensalism
• C. Parasitism
• D. Predation

Correct answer: B

Rationale: B) Commensalism: In commensalism, one organism benefits while the other is neither helped nor harmed. This is the relationship described in the question. The correct answer is Commensalism because it specifically fits the scenario where one organism benefits without affecting the other. A) Mutualism: In mutualism, both organisms involved benefit from the relationship. C) Parasitism: In parasitism, one organism benefits at the expense of the other organism, which is harmed. D) Predation: In predation, one organism (predator) kills and consumes another organism (prey) for food.

3. When it gets warm in the spring, _______ and _______ like to go fishing at Cobbs Creek. Which of the following word pairs should be used in the blanks above?

• A. me, him
• B. he, I
• C. him, I
• D. he, me

Correct answer: C

Rationale: The correct word pair to use in this context is 'him, I.' This is because 'him' and 'I' are the correct pronouns to refer to two individuals in the third person (him) and first person (I). The sentence should indicate that when it gets warm in the spring, 'him' and 'I' like to go fishing at Cobbs Creek. Choice A, 'me, him,' is incorrect as 'me' should be replaced with 'I' to maintain proper subject-object agreement. Choice B, 'he, I,' is incorrect as 'he' should be replaced with 'him' to properly refer to the other person involved. Choice D, 'he, me,' is incorrect as 'me' should be replaced with 'I' to maintain the correct pronoun usage.

4. What is 0.175 mg in mcg?

• A. 175 mcg
• B. 1.75 mcg
• C. 1750 mcg
• D. 17.5 mcg

Correct answer: C

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in 1 milligram. Therefore, 0.175 mg x 1000 = 1750 mcg. The correct answer is 1750 mcg. Choices A, B, and D are incorrect because they do not account for the conversion factor of 1000 between milligrams and micrograms. It's crucial to understand these conversions in medical calculations to ensure accurate dosing and prevent medication errors.

5. Which of the following lobes of the brain is responsible for sensation, perception, and spatial reasoning?

• A. Frontal
• B. Occipital
• C. Parietal
• D. Temporal

Correct answer: C

Rationale: The parietal lobe is responsible for sensation, perception, and spatial reasoning. It plays a crucial role in processing sensory information, assisting in spatial orientation, and integrating various sensory inputs to create a comprehensive perception of the surrounding environment. The frontal lobe, although important for higher cognitive functions and motor skills, is not primarily responsible for sensation, perception, or spatial reasoning. The occipital lobe is mainly involved in visual processing, and the temporal lobe is primarily associated with auditory processing, memory, and emotions, making them incorrect choices for this question.
