1. The prefix 'milli' stands for 0.001 (10^-3). This means, 1 mm is the same as:

• A. 0.01 m
• B. 0.001 m
• C. 0.1 m
• D. 1 m

Correct answer: B

Rationale: The correct answer is B: '0.001 m.' The prefix 'milli' represents a factor of 10^-3, which means one millimeter (mm) is equivalent to 0.001 meters (m). Therefore, 1 mm is equal to 0.001 m. Choice A, '0.01 m,' is incorrect as it represents 0.01 meters, not 0.001 meters. Choice C, '0.1 m,' is incorrect because it stands for 0.1 meters, which is 10 times greater than 1 mm. Choice D, '1 m,' is incorrect as it represents 1 meter, which is 1000 times greater than 1 mm.

2. Which of the following sentences contains an indirect object?

• A. Melissa walked to the grocery store for milk.
• B. Dante skimmed the magazine while waiting in the lobby.
• C. Jorge assigned the class some math problems.
• D. Sara went to the movie with Amal.

Correct answer: C

Rationale: In sentence C, 'Jorge assigned the class some math problems,' 'the class' is the indirect object receiving the direct object 'some math problems.' In this sentence, 'the class' is the recipient of the action, making it the indirect object. The other choices do not contain an indirect object. In sentences A, B, and D, there are no instances of an indirect object. Therefore, the correct answer is C.

3. A book has a width of 5 decimeters. What is the width of the book in centimeters?

• A. 0.25 centimeters
• B. 25 centimeters
• C. 250 centimeters
• D. 0.025 centimeters

Correct answer: B

Rationale: To convert decimeters to centimeters, you need to multiply by 10 since 1 decimeter is equal to 10 centimeters. Therefore, to find the width of the book in centimeters, multiply 5 decimeters by 10: 5 decimeters * 10 = 50 centimeters. This means the width of the book is 50 centimeters, making choice B, "25 centimeters," the correct answer. Choices A, C, and D are incorrect because they do not correctly convert decimeters to centimeters.

4. What is the difference between type 1 and type 2 diabetes, both related to insulin and blood sugar?

• A. Type 1 is caused by insulin resistance, type 2 by insulin deficiency.
• B. Type 1 is temporary, type 2 is permanent.
• C. Type 1 affects adults, type 2 affects children.
• D. Type 1 is treated with diet only, type 2 requires medication.

Correct answer: A

Rationale: The correct difference between type 1 and type 2 diabetes lies in their underlying causes. Type 1 diabetes is caused by the body's inability to produce insulin, while type 2 diabetes is characterized by insulin resistance, where the body doesn't effectively use the insulin it produces. Insulin resistance is a key feature of type 2 diabetes, distinguishing it from type 1 where insulin deficiency is the primary issue. Choices B, C, and D are incorrect. Type 1 and type 2 diabetes can both be chronic conditions, affecting individuals of different age groups, and typically require a combination of diet, exercise, and medication for management.

5. Neurons, the functional units of the nervous system, belong to which tissue type?

• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue

Correct answer: D

Rationale: Neurons are the functional units of the nervous system and are specialized cells that transmit nerve impulses. They belong to nervous tissue, which is the primary tissue type of the nervous system. Nervous tissue is composed of neurons and supporting cells called neuroglia. Choices A, B, and C are incorrect because epithelial tissue functions mainly in covering and lining body surfaces, connective tissue provides support and structure, and muscle tissue is responsible for movement. Neurons, being the basic functional units of the nervous system, are specifically classified under nervous tissue.
