1. Which term describes the ability of a substance to conduct electricity?

Correct answer: C

Rationale: Conductivity is the correct term used to describe the ability of a substance to conduct electricity. Reactivity is the measure of a substance's tendency to undergo chemical reactions. Density refers to the mass per unit volume of a substance, while viscosity is a measure of a fluid's resistance to flow. In the context of conducting electricity, conductivity is the most appropriate term as it directly relates to the substance's electrical conductive properties.

2. A person wakes up with a fever. The body begins its response to locate the origin of the problem and fix it. What type of feedback mechanism is this?

Correct answer: B

Rationale: This scenario describes a negative feedback mechanism. When the body detects a fever, it initiates responses to lower the temperature back to normal levels. Negative feedback mechanisms work to counteract changes and maintain homeostasis in the body. Choice A ('Equal') is incorrect as feedback mechanisms aim to restore balance, not maintain an equal state. Choice C ('Neutral') is incorrect as it does not describe the corrective nature of negative feedback. Choice D ('Positive') is incorrect as it would amplify the fever rather than regulate it.

3. Which muscular tube carries urine from the kidneys to the bladder?

Correct answer: B

Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. The nephron is the functional unit of the kidney responsible for filtering blood and producing urine. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a network of capillaries in the nephron where filtration of blood occurs.

4. Which of the following is not a type of muscle tissue?

Correct answer: D

Rationale: The correct answer is D, Adipose. Adipose tissue is a type of connective tissue that stores fat, not muscle tissue. Skeletal, smooth, and cardiac are all types of muscle tissues found in the body. Skeletal muscle tissue is responsible for voluntary movements and is attached to bones. Smooth muscle tissue is found in the walls of hollow organs and blood vessels, responsible for involuntary movements. Cardiac muscle tissue is found in the heart and is responsible for pumping blood throughout the body. Adipose tissue, on the other hand, primarily functions as a storage site for energy in the form of fat.

5. Which of the following best describes the function of the pericardium?

Correct answer: B

Rationale: The pericardium is a double-layered sac that surrounds and protects the heart. Its main functions include preventing overfilling of the heart, providing a physical barrier against infection and inflammation, and reducing friction between the heart and surrounding structures. Choices A, C, and D do not accurately describe the function of the pericardium. Option B is the correct answer as it aligns with the protective and supportive role of the pericardium, distinguishing it from the functions attributed to choices A, C, and D.
