1. Which of the following is NOT an example of an intermolecular force?

Correct answer: C

Rationale: Ionic bonding is not considered an intermolecular force but an intramolecular force. Intermolecular forces occur between different molecules, while intramolecular forces act within a molecule. Hydrogen bonding, dipole-dipole interactions, and London dispersion forces are intermolecular forces. Hydrogen bonding involves a hydrogen atom bonded to a highly electronegative atom, dipole-dipole interactions occur between polar molecules, and London dispersion forces are temporary attractions between nonpolar molecules.

2. What is the term used to describe the inability of the kidneys to effectively filter waste products from the blood?

Correct answer: B

Rationale: Kidney failure is the term used to describe the inability of the kidneys to effectively filter waste products from the blood. Dehydration refers to insufficient fluid intake and not the kidney's filtering function. Incontinence is the loss of bladder control, not related to kidney filtration. Nephritis is the inflammation of the kidneys, not specifically related to the kidneys' inability to filter waste products.

3. What is the relationship between the wavelength (λ) and frequency (f) of a wave with a constant speed (v)?

Correct answer: A

Rationale: The relationship between wavelength (λ), frequency (f), and speed (v) of a wave is given by the formula λ = v / f. This formula is derived from the wave equation v = fλ, where v is the speed of the wave, f is the frequency, and λ is the wavelength. By rearranging the equation, we get λ = v / f, indicating that the wavelength is inversely proportional to the frequency when the speed of the wave is constant. Therefore, choice A, λ = v / f, correctly represents the relationship between wavelength and frequency when the speed of the wave is held constant. Choice B, λ = f / v, is incorrect because it represents an inverse relationship between wavelength and speed, which is not the case. Choice C, λ = vf, is incorrect as it implies a direct relationship between wavelength, frequency, and speed, which is not accurate. Choice D, λ is independent of f and v, is incorrect as both frequency and speed affect the wavelength of a wave, as shown by the correct formula λ = v / f.

4. Which protein complex in the sarcomere is responsible for the thick filament?

Correct answer: B

Rationale: Myosin is the protein complex responsible for the thick filament in the sarcomere. It interacts with actin, another protein in the sarcomere, to generate the sliding movement that results in muscle contraction. Actin is a thin filament protein that interacts with myosin to create the sliding filament mechanism. Tropomyosin and troponin are regulatory proteins that regulate muscle contraction by controlling the interaction between actin and myosin, rather than directly being responsible for the thick filament.

5. Which of the following is NOT part of the circulatory system?

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are part of the urinary system, responsible for filtering waste and maintaining fluid balance in the body. In the circulatory system, the heart pumps blood, blood carries oxygen and nutrients, and blood vessels transport blood throughout the body. Choices B, C, and D are all components of the circulatory system, making the kidneys the correct choice as it belongs to the urinary system.
