1. What is the term for the inflammation of the airways in the lungs, often causing wheezing and difficulty breathing?

• A. Pneumonia
• B. Emphysema
• C. Asthma
• D. Pleurisy

Correct answer: C

Rationale: The correct answer is C: "Asthma." Asthma is a chronic condition characterized by inflammation of the airways in the lungs, leading to symptoms like wheezing, shortness of breath, coughing, and chest tightness. Pneumonia (A) is an infection in the lungs caused by bacteria, viruses, or fungi. Emphysema (B) is a type of chronic obstructive pulmonary disease (COPD) characterized by damage to the air sacs in the lungs. Pleurisy (D) is inflammation of the lining of the lungs and chest cavity. Therefore, asthma best fits the description provided in the question, making it the correct answer.

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. Which of the following substances is typically a good conductor of electricity when dissolved in water?

• A. Sugar
• B. Sodium chloride
• C. Olive oil
• D. Oxygen gas

Correct answer: b

Rationale: Ionic compounds like sodium chloride dissociate into ions in water, making the solution conductive. The other choices do not typically conduct electricity in water.

4. What effect does doubling the net force applied to an object have on its acceleration, assuming mass remains constant?

• A. Acceleration doubles
• B. Acceleration is halved
• C. Acceleration remains the same
• D. Acceleration quadruples

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass remains constant and force doubles, acceleration also doubles.

5. Semen, the fluid that carries sperm, is produced by a gland within the male reproductive system. Which gland is responsible for this?

• A. Testes
• B. Scrotum
• C. Prostate gland
• D. Seminal vesicles

Correct answer: D

Rationale: The correct answer is D: Seminal vesicles. The seminal vesicles are responsible for producing the fluid component of semen, which nourishes and protects sperm as they travel through the reproductive system. While the testes produce sperm, the scrotum is the external sac that holds the testes, and the prostate gland also contributes to semen production but does not produce the fluid itself. Understanding the roles of each gland in the male reproductive system is important for comprehending the process of sperm production and ejaculation.

6. A 10 kg box rests on a frictionless surface. A horizontal force of 20 N is applied to the box. What is the box's acceleration?

• A. 0.5 m/s²
• B. 1 m/s²
• C. 2 m/s²
• D. 10 m/s²

Correct answer: C

Rationale: Use Newton's second law, F = ma, where F is the net force, m is the mass, and a is the acceleration. Since there is no friction, the net force equals the applied force (20 N). Therefore, a = F/m = 20 N / 10 kg ≈ 2 m/s².
