Anatomy

1. How does lymph move through the lymphatic vessels?

Correct answer: D

Rationale: The correct answer is D: "All of the above." Lymph, a clear fluid that carries immune cells and waste products, moves through the lymphatic vessels by multiple mechanisms. While the pumping action of the heart plays a minor role, the primary driving forces are muscle contractions and breathing movements that squeeze the vessels. Additionally, lymphatic vessels contain one-way valves that prevent the backward flow of lymph, ensuring that it moves in the right direction. Therefore, all of the options provided contribute to the movement of lymph through the lymphatic system.

2. Which of the following is an example of a decomposition reaction?

Correct answer: b

Rationale: Decomposition reactions involve the breakdown of a compound into simpler substances.

3. If 3 nurses can care for 15 patients, how many nurses are needed for 25 patients?

Correct answer: B

Rationale: 3 nurses / 15 patients = x nurses / 25 patients. Solve for x.

4. The term "symbiotic relationship" describes an interaction between two organisms where:

Correct answer: D

Rationale: Rationale: In a symbiotic relationship, both organisms involved benefit from the interaction. This mutually beneficial relationship can take different forms, such as mutualism where both organisms benefit, commensalism where one organism benefits and the other is unaffected, or parasitism where one organism benefits at the expense of the other. In this case, the term "symbiotic relationship" specifically refers to a scenario where both organisms derive some form of benefit from their interaction.

5. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?

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.

6. Which property of a wave remains constant when the wave enters a different medium?

Correct answer: d

Rationale: The speed of a wave remains constant when it enters a different medium, provided the conditions are unchanged.
