1. Which plane divides the body into superior (top) and inferior (bottom) halves?

• A. Sagittal/Median Plane
• B. Frontal/Coronal Plane
• C. Transverse/Cross-Section Plane
• D. Horizontal Plane

Correct answer: C

Rationale: The Transverse or Cross-Section Plane is the correct answer as it divides the body into superior (top) and inferior (bottom) halves. This plane runs horizontally across the body, perpendicular to the long axis, separating the body into upper and lower sections. Choice A, the Sagittal/Median Plane, divides the body into left and right halves, not superior and inferior halves. Choice B, the Frontal/Coronal Plane, divides the body into anterior (front) and posterior (back) halves. Choice D, the Horizontal Plane, is not a standard anatomical plane used to divide the body into specific sections.

2. How does an increase in surface area affect the force of friction between two surfaces?

• A. Increases friction
• B. Decreases friction
• C. Has no effect on friction
• D. Causes unpredictable changes in friction

Correct answer: A

Rationale: An increase in surface area typically increases the force of friction between two surfaces. This is because with a larger surface area in contact, there are more points of contact between the surfaces, leading to a greater frictional force resisting motion. As a result, the correct answer is that an increase in surface area increases the force of friction between two surfaces. Choice B is incorrect because a greater surface area increases the frictional force. Choice C is incorrect because an increase in surface area results in more contact points and greater friction. Choice D is incorrect as the relationship between surface area and friction is predictable - an increase in surface area generally leads to an increase in frictional force.

3. What are the moon-shaped white structures at the base of fingernails called?

• A. Lunulae
• B. Cuticle
• C. Hyponychium
• D. Matrix

Correct answer: A

Rationale: The correct answer is A: Lunulae. The moon-shaped white structures at the base of fingernails are known as lunulae. They are most prominent on the thumb and are situated at the base of the nail matrix. The lunula is the visible part of the nail matrix, which is responsible for generating new nail cells. Choice B, Cuticle, is incorrect as it refers to the thin layer of skin at the base of the nail plate. Choice C, Hyponychium, is incorrect as it is the skin that lies beneath the free edge of the nail. Choice D, Matrix, is incorrect as it is the area where the nail is formed, located under the cuticle.

4. During exercise, oxygen is used to convert glucose into energy for muscles. This process is called:

• A. Aerobic respiration
• B. Anaerobic respiration
• C. Glycolysis
• D. Lactic acid fermentation

Correct answer: A

Rationale: Aerobic respiration is the process by which cells use oxygen to convert glucose into energy. This process occurs in the mitochondria of cells and is the most efficient way to produce energy during exercise. Anaerobic respiration and glycolysis are alternative pathways for energy production when oxygen is limited, typically occurring during high-intensity exercise. Lactic acid fermentation, on the other hand, occurs in the absence of oxygen and leads to the production of lactic acid, causing muscle fatigue and soreness.

5. Which type of reasoning has the FBI agent 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 general conclusions from specific observations or instances. In this case, the FBI agent is creating a theory based on observations of specific cases rather than applying a general rule to a specific situation (which would be deductive reasoning). Conductive reasoning is not a recognized type of reasoning, and quantitative reasoning involves interpreting and analyzing quantitative information.
