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. What is the general formula for an alkene?

• A. CnH2n+2
• B. CnH2n
• C. CnH2n-2
• D. CnH2n+1

Correct answer: B

Rationale: The general formula for an alkene is \(C_nH_{2n}\), indicating the presence of a double bond between carbon atoms.

3. During which phase of the cardiac cycle do the atria contract, pushing blood into the ventricles?

• A. Atrial diastole
• B. Ventricular systole
• C. Atrial systole
• D. Ventricular diastole

Correct answer: C

Rationale: Atrial systole is the phase of the cardiac cycle during which the atria contract, pushing blood into the ventricles. This occurs after the atria have been filled during atrial diastole. Ventricular systole refers to the phase when the ventricles contract to push blood out of the heart, not when the atria contract. Ventricular diastole is the phase when the ventricles relax and fill with blood, not when the atria contract. Therefore, the correct answer is atrial systole as it specifically describes the atrial contraction phase.

4. What property of a substance remains constant regardless of its location in the universe?

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

Correct answer: A

Rationale: Mass is a measure of the amount of matter in an object and remains constant regardless of its location in the universe. Weight, on the other hand, is the force of gravity acting on an object and can vary depending on the gravitational pull at different locations. Density and volume can also change based on the environment in which an object is placed, making mass the property that remains constant universally. Therefore, the correct answer is mass. Weight changes with the gravitational force of a particular location, density varies with mass and volume, and volume can change depending on the shape or size of the object.

5. What is the primary function of red blood cells?

• A. To transport nutrients
• B. To transport oxygen
• C. To fight infection
• D. To produce antibodies

Correct answer: B

Rationale: The correct answer is B: To transport oxygen. Red blood cells play a crucial role in carrying oxygen from the lungs to all the tissues and organs in the body. This oxygen transport is essential for cellular respiration, where oxygen is used in the production of energy. Red blood cells do not primarily transport nutrients, fight infection, or produce antibodies. Choice A is incorrect because while red blood cells do carry some nutrients, their primary function is to transport oxygen. Choice C is incorrect because immune cells, not red blood cells, are responsible for fighting infections. Choice D is incorrect as antibody production is mainly carried out by specialized white blood cells, not red blood cells.
