1. What is the term for the time it takes for a wave to complete one full cycle?

• A. Frequency
• B. Amplitude
• C. Period
• D. Wavelength

Correct answer: c

Rationale: The period of a wave is the time taken for one complete oscillation or cycle.

2. What is the scientific term for the windpipe, a tube that carries air from the larynx to the bronchi?

• A. Pharynx
• B. Trachea
• C. Epiglottis
• D. Bronchiole

Correct answer: B

Rationale: The correct answer is B: Trachea. The trachea is the scientific term for the windpipe, which is a tube that carries air from the larynx to the bronchi. The pharynx is the throat area where the mouth and nasal passages meet. The epiglottis is a flap of tissue that covers the trachea during swallowing to prevent food from entering the airway. Bronchioles are smaller airway branches in the lungs. Therefore, the trachea best fits the description of a tube carrying air from the larynx to the bronchi.

3. Choose the most appropriate word to complete the sentence "He was _____ about his upcoming presentation."

• A. apprehensive
• B. bored
• C. excited
• D. relieved

Correct answer: A

Rationale: "Apprehensive" implies a mild worry or nervousness, which best fits the context.

4. Describe the concept of inertia in terms of Newton's first law.

• A. Objects in motion tend to remain in motion unless acted upon by an external force
• B. Objects at rest tend to remain at rest unless acted upon by an external force
• C. An object's resistance to a change in its state of motion
• D. The force required to lift an object

Correct answer: c

Rationale: Inertia refers to an object's tendency to maintain its current state of motion (either at rest or in motion) unless acted upon by an external force.

5. Antibiotic resistance in bacteria is an example of:

• A. Convergent evolution
• B. Divergent evolution
• C. Microevolution
• D. Macroevolution

Correct answer: C

Rationale: Rationale: - Convergent evolution (option A) refers to the process by which different species evolve similar traits independently in response to similar environmental pressures. Antibiotic resistance in bacteria does not involve different species evolving similar traits. - Divergent evolution (option B) refers to the process by which two or more related species become more dissimilar over time. Antibiotic resistance in bacteria does not involve related species becoming more dissimilar. - Microevolution (option C) refers to changes in allele frequencies within a population over a relatively short period of time. Antibiotic resistance in bacteria is a classic example of microevolution, where bacteria evolve resistance to antibiotics through the natural selection of pre-existing resistant strains. - Macroevolution (option D) refers to large-scale evolutionary changes that result in the formation of new species or higher taxonomic groups. Antibiotic resistance in bacteria does not involve

6. Which of the following is NOT a method of sterilization?

• A. Autoclave
• B. UV light
• C. Chemical disinfectants
• D. Boiling water

Correct answer: D

Rationale: Rationale: A) Autoclave: An autoclave is a method of sterilization that uses high pressure and steam to kill microorganisms, making it an effective way to sterilize equipment and materials. B) UV light: UV light is a method of sterilization that damages the DNA of microorganisms, preventing them from reproducing and causing infections. C) Chemical disinfectants: Chemical disinfectants are used to kill or inactivate microorganisms on surfaces, but they may not always achieve sterilization, which is the complete destruction of all microorganisms. D) Boiling water: Boiling water is a method of disinfection rather than sterilization. While boiling water can kill many microorganisms, it may not be effective against all types of bacteria, viruses, and spores, making it unsuitable for achieving sterilization. Therefore, the correct answer is D) Boiling water, as it is not a method of sterilization
