1. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?
- A. Limiting high-sodium foods in the diet
- B. Consuming adequate amounts of cranberry juice
- C. Holding urine in the bladder for long periods
- D. Getting regular moderate-intensity exercise
Correct answer: C
Rationale: The correct answer is C: Holding urine in the bladder for long periods. This is not recommended for optimal urinary system health because it can increase the risk of urinary tract infections and bladder problems. It is important to empty the bladder regularly to prevent bacteria from multiplying and causing infections. Limiting high-sodium foods in the diet helps maintain kidney health by reducing the risk of kidney stones and high blood pressure. Consuming cranberry juice can help prevent urinary tract infections due to its antibacterial properties. Regular moderate-intensity exercise promotes overall health, including good circulation to the kidneys and bladder.
2. Which of the following substances is an example of an acidic gas?
- A. Nitrogen (Nâ‚‚)
- B. Carbon dioxide (COâ‚‚)
- C. Sulfur dioxide (SOâ‚‚)
- D. Oxygen (Oâ‚‚)
Correct answer: C
Rationale: Sulfur dioxide is an acidic gas. The other choices are either neutral or basic gases.
3. Which statement accurately defines power?
- A. Power is the amount of energy stored in an object
- B. Power is the rate at which energy is transferred or work is done
- C. Power is the maximum force exerted by an object
- D. Power is the resistance of an object to change in motion

6. Which of the following structures plays a crucial role in controlling the cell cycle and preventing uncontrolled cell growth?
- A. The centrioles
- B. The nucleolus
- C. The Golgi apparatus
- D. The endoplasmic reticulum
Correct answer: A
Rationale: Rationale: - Centrioles are cylindrical structures found in animal cells that play a crucial role in organizing the spindle fibers during cell division (mitosis). They are involved in the separation of chromosomes during cell division, ensuring that each daughter cell receives the correct number of chromosomes. - Centrioles are also involved in the formation of cilia and flagella, which are important for cell motility and sensory functions. - The other structures listed in the options (nucleolus, Golgi apparatus, and endoplasmic reticulum) do not directly play a role in controlling the cell cycle and preventing uncontrolled cell growth.
