1. What is the scientific name for the common housefly?

Correct answer: A

Rationale: Rationale: - Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. - Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. - Apis mellifera (option C) is the scientific name for the western honeybee. - Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

2. Which of the following conditions is characterized by a wasting or decrease in muscle mass?

Correct answer: B

Rationale: The correct answer is B: 'Atrophy.' Atrophy is a condition characterized by a wasting or decrease in muscle mass. Hypertrophy (choice A) refers to an increase in muscle size, not a decrease. Spasticity (choice C) is increased muscle tone and reflexes, while myopathy (choice D) is a general term for diseases of the muscle tissue. Understanding these definitions is crucial for distinguishing between different muscle conditions.

3. Beta waves, associated with alertness and focused attention, typically fall within the range of:

Correct answer: D

Rationale: Beta waves are neural oscillations in the brain that are associated with alertness, concentration, and active thinking. They typically fall within the frequency range of 13-30 Hz. This range is indicative of a person being awake, alert, and engaged in cognitive tasks requiring focus. Lower frequency ranges like 0.5-4 Hz (Delta waves) are associated with deep sleep and unconsciousness, while higher ranges like 8-13 Hz (Alpha waves) are linked to a relaxed and meditative state. Therefore, option D (13-30 Hz) is the correct range for beta waves, reflecting the brain's heightened activity during periods of attentiveness and concentration.

4. What defines the period of a wave?

Correct answer: C

Rationale: The period of a wave is defined as the time it takes for one complete wave cycle to pass a point. It is typically measured in seconds and is inversely related to the frequency of the wave. The period is not related to the number of waves passing a point per unit time (A), the distance between two adjacent crests or troughs (B), or the maximum displacement of particles in a medium due to the wave (D).

5. The phrase "illuminates not only past events" suggests that history

Correct answer: B

Rationale: The phrase highlights that history goes beyond mere chronology, offering valuable insights and lessons beyond the dates and facts.

6. Which technique best helps maintain consistency in writing style?
