1. What term describes the phenomenon of two waves canceling each other out when they meet?

• A. Refraction
• B. Diffraction
• C. Destructive interference
• D. Constructive interference

Correct answer: C

Rationale: Destructive interference occurs when two waves meet and their amplitudes are such that they cancel each other out, resulting in a wave with a smaller amplitude or no wave at all. This is in contrast to constructive interference, where two waves combine to produce a wave with a larger amplitude. Refraction and diffraction are phenomena related to the bending of waves as they pass through different mediums or obstacles, respectively.

2. 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

3. What is the largest muscle in the human body?

• A. Gluteus maximus (buttocks)
• B. Quadriceps femoris (thighs)
• C. Erector spinae (back)
• D. Pectoralis major (chest)

Correct answer: A

Rationale: The gluteus maximus is the largest muscle in the human body, located at the back of the hip and extending from the sacrum to the femur. It is a powerful muscle that plays a crucial role in extending the hip joint, enabling walking, running, and climbing stairs.

4. Which word best synonyms with the word "elated"?

• A. Angry
• B. Sad
• C. Excited
• D. Confused

Correct answer: C

Rationale: "Elated" and "excited" both convey feelings of happiness and enthusiasm.

5. What is the acceleration of an object moving at a constant speed of 20 m/s if it comes to a complete stop within 5 seconds?

• A. 0 m/s² (no acceleration)
• B. 4 m/s²
• C. -4 m/s²
• D. Information insufficient

Correct answer: C

Rationale: The acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 0 m/s (as the object comes to a complete stop), the initial velocity is 20 m/s, and the time taken is 5 seconds. Plugging these values into the formula, we get acceleration = (0 m/s - 20 m/s) / 5 s = -20 m/s / 5 s = -4 m/s². Therefore, the acceleration is -4 m/s².

6. Which of the following is the main organ responsible for producing bile?

• A. Liver
• B. Gallbladder
• C. Pancreas
• D. Stomach

Correct answer: A

Rationale: Rationale: The liver is the main organ responsible for producing bile. Bile is a greenish-yellow fluid that is produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion and absorption of fats in the small intestine. The gallbladder releases bile into the small intestine when needed to aid in the digestion of fats. The pancreas is responsible for producing digestive enzymes and insulin, not bile. The stomach is primarily involved in the digestion of food through the secretion of gastric juices.
