1. Of the individuals described below, who seems like the best applicant for the roommate advertisement?

Correct answer: C

Rationale: The best applicant for the roommate advertisement is Cosette. The ad specifies that the current occupants are quiet, the house is clean/smoke-free, and no pets are allowed. Cosette is allergic to cigarette smoke, indicating she is a non-smoker and prefers a smoke-free environment. She also needs a quiet place to study, aligning with the quiet environment mentioned in the ad. Additionally, the ad prefers long-term applicants, and Cosette's need for a quiet place to study implies she will likely remain for an extended period. Frances owning a Yorkshire terrier goes against the ad's 'no pets' policy. Adelaide seeking a three-month rental does not align with the preference for long-term applicants. Felix not owning a car is not relevant to the criteria set by the ad.

2. How does the amplitude of a wave relate to its intensity or loudness?

Correct answer: B

Rationale: The amplitude of a wave is directly related to its intensity or loudness. In general, the larger the amplitude of a wave, the greater its intensity or loudness. This relationship is due to the fact that the amplitude of a wave represents the maximum displacement of particles in the medium from their rest position. The greater the displacement, the more energy the wave carries, leading to higher intensity or louder sound. Choice A is incorrect because the relationship between amplitude and intensity is direct, not inverse. Choice C is incorrect as there is a clear relationship between amplitude and intensity. Choice D is incorrect as amplitude primarily affects intensity or loudness, not frequency.

3. Which of the following is a unit of power?

Correct answer: C

Rationale: The correct answer is C: Watt (W). Power is the rate at which work is done or energy is transferred. The unit of power is the watt (W), named after James Watt, the inventor of the steam engine. A Newton-meter (N·m) is a unit of torque, Joule (J) is a unit of energy, and Kilogram (kg) is a unit of mass, not power. Therefore, choices A, B, and D are incorrect as they represent units of torque, energy, and mass, respectively, and not power.

4. Which neurotransmitter is responsible for stimulating muscle contraction?

Correct answer: B

Rationale: Acetylcholine is the neurotransmitter responsible for stimulating muscle contraction at the neuromuscular junction. When an action potential reaches the end of a motor neuron, acetylcholine is released into the synaptic cleft and binds to receptors on the muscle cell membrane, leading to muscle contraction. Dopamine, serotonin, and norepinephrine are neurotransmitters that have different functions in the nervous system and are not directly involved in stimulating muscle contraction. Dopamine is involved in reward and pleasure pathways, serotonin regulates mood and behavior, and norepinephrine is involved in the 'fight or flight' response.

5. Mesosomes are the internal extensions of which of the following?

Correct answer: B

Rationale: Mesosomes are the internal extensions of the cell membrane, not the capsule, cell wall, or chromatin body. They play a crucial role in cell division and are essential for various cellular processes such as respiration and cell wall formation. Mesosomes are not associated with the capsule (choice A), cell wall (choice C), or chromatin body (choice D), making these options incorrect.
