1. The lymphatic system is a network of vessels and organs that plays a vital role in:

• A. Transporting oxygen and nutrients to cells
• B. Carrying waste products away from tissues
• C. Regulating body temperature
• D. Producing red blood cells

Correct answer: B

Rationale: The correct answer is B: Carrying waste products away from tissues. The lymphatic system is responsible for collecting excess fluid and waste products from tissues and returning them to the bloodstream for removal. This helps maintain fluid balance in the body and supports immune function by transporting white blood cells to fight infections. Options A, C, and D do not accurately describe the function of the lymphatic system. Transporting oxygen and nutrients to cells is primarily the role of the circulatory system, while regulating body temperature is controlled by the nervous system and producing red blood cells occurs in the bone marrow.

2. What is the scientific term for inflammation of the bronchi, often associated with a cough and mucus production?

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

Correct answer: B

Rationale: The correct answer is B: Bronchitis. Bronchitis is the scientific term for inflammation of the bronchi, which are the air passages in the lungs. This condition is often characterized by a cough, mucus production, and difficulty breathing. Pneumonia (A) is an infection that causes inflammation in the air sacs in the lungs, not the bronchi. Emphysema (C) is a chronic lung condition that results in the damage of the air sacs in the lungs, leading to difficulty breathing. Pleurisy (D) is inflammation of the pleura, the lining around the lungs, and is not directly related to inflammation of the bronchi. Therefore, option B is the correct answer in this case.

4. What property of matter refers to the amount of space occupied by an object and is measured in cubic units?

• A. Mass
• B. Density
• C. Weight
• D. Volume

• A. Chemical change
• B. Physical change
• C. Nuclear change

6. How is power related to work and time?

• A. Power = Work ÷ Time
• B. Power = Work × Time
• C. Power = Work + Time
• D. Power = Work - Time

Correct answer: a

Rationale: Power is calculated as the amount of work done or energy transferred per unit of time.
