1. What type of energy does a stretched rubber band possess?

• A. Kinetic energy
• B. Potential energy
• C. Thermal energy
• D. Mechanical energy

Correct answer:

Rationale: When a rubber band is stretched, it stores potential energy due to its position or state.

2. What is the process of breaking down proteins into amino acids called?

• A. Proteolysis
• B. Lipolysis
• C. Carbohydrate catabolism
• D. Nucleic acid catabolism

Correct answer: A

Rationale: Rationale: Proteolysis is the process of breaking down proteins into amino acids. Lipolysis is the breakdown of fats into fatty acids and glycerol, not proteins. Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production. Nucleic acid catabolism is the breakdown of nucleic acids into nucleotides. In this context, the specific process of breaking down proteins into amino acids is best described by proteolysis.

3. What is the primary difference between science and pseudoscience?

• A. Science uses complex terminology and jargon, while pseudoscience is easier to understand.
• B. Science relies on rigorous methodology and evidence, while pseudoscience thrives on personal anecdotes and testimonials.
• C. Science caters to specific fields of study, while pseudoscience encompasses broader life questions.
• D. Science is conducted by professionals, while pseudoscience is pursued by amateurs with limited knowledge.

Correct answer: B

Rationale: Both science and pseudoscience can explore similar topics, but their methods and reliance on evidence differentiate them.

4. What happens to the frequency of a wave when its wavelength is doubled, assuming the speed remains constant?

• A. Frequency remains the same.
• B. Frequency is halved.
• C. Frequency is doubled.
• D. Frequency information is insufficient to determine.

Correct answer: C

Rationale: Since the wave speed is constant, if the wavelength increases, the frequency must decrease to maintain the same energy transfer per unit time.

5. The process by which a solid changes directly into a liquid is called:

• A. Melting
• B. Condensation
• C. Sublimation
• D. Deposition

Correct answer: D

Rationale: While melting is a solid to liquid transition, deposition, also known as sublimation, refers to a gas directly changing into a solid.

6. The body's first line of defense against pathogens includes:

• A. Phagocytes
• B. Antibodies
• C. Memory B cells
• D. T lymphocytes

Correct answer: A

Rationale: Rationale: Phagocytes are a type of white blood cell that plays a crucial role in the body's innate immune response, which is the first line of defense against pathogens. Phagocytes engulf and digest foreign particles, such as bacteria and viruses, helping to prevent infection and disease. Antibodies (option B) are produced by B cells and are part of the adaptive immune response, not the first line of defense. Memory B cells (option C) are also part of the adaptive immune response and are involved in mounting a faster and stronger response upon re-exposure to a pathogen. T lymphocytes (option D) are another type of white blood cell involved in the adaptive immune response, specifically in cell-mediated immunity.
