1. 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.

2. Which of the following is considered an intensive property?

• A. Mass
• B. Weight
• C. Volume
• D. Density

Correct answer: D

Rationale: Density is an intensive property because it does not depend on the amount of matter present. Intensive properties are independent of the quantity of the substance and remain constant regardless of the size or amount of the sample being measured. Mass, weight, and volume are extensive properties that depend on the amount of substance present. Mass and weight change with the amount of matter, while volume changes as the quantity of the substance changes. Therefore, they are not considered intensive properties.

3. Which of the following minerals is important for bone health and is stored in bones by the skeletal system?

• A. Iron
• B. Sodium
• C. Calcium
• D. Magnesium

Correct answer: C

Rationale: The correct answer is Calcium (Choice C). Calcium is essential for bone health and is stored in bones by the skeletal system. Bones act as a reservoir for calcium, playing a critical role in maintaining bone strength and density. Iron, sodium, and magnesium are important for various bodily functions but are not primarily stored in bones for bone health. Iron is crucial for oxygen transport, sodium helps regulate fluid balance, and magnesium is involved in over 300 enzymatic reactions in the body.

4. Which of the following processes breaks down cellular components for recycling or waste removal?

• A. Photosynthesis
• B. Cellular respiration
• C. Cell division
• D. Phagocytosis

Correct answer: D

Rationale: The correct answer is D: Phagocytosis. Phagocytosis is the process by which cells engulf and break down cellular components or foreign particles for recycling or waste removal. It is a vital mechanism used by cells to maintain homeostasis and remove waste materials. Photosynthesis (A) is the process by which plants convert light energy into chemical energy to produce food, not for breaking down cellular components. Cellular respiration (B) is the process by which cells generate energy from nutrients, not for waste removal. Cell division (C) is the process by which cells replicate and divide to form new cells during growth, repair, or development, not for breaking down cellular components.

5. What is the molar mass of Ca(NO3)2?

• A. 74.1 g/mol
• B. 132.1 g/mol
• C. 164.1 g/mol
• D. 78.1 g/mol

Correct answer: B

Rationale: To calculate the molar mass of Ca(NO3)2, we add up the individual atomic masses of its elements: Ca (40.08) + 2N (2 * 14.01) + 6O (6 * 16.00) = 40.08 + 28.02 + 96.00 = 164.1 g/mol. Therefore, the correct answer is 164.1 g/mol (Choice C). Choice A (74.1 g/mol) is incorrect as it does not account for the correct sum of atomic masses. Choice B (132.1 g/mol) is the correct molar mass calculation for Ca(NO3)2. Choice D (78.1 g/mol) is incorrect and does not reflect the accurate molar mass of the compound.
