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

• A. One organism benefits and the other is unaffected
• B. Both organisms are harmed by the interaction
• C. One organism benefits and the other is negatively impacted
• D. Both organisms benefit from the interaction

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.

2. Which test is commonly used to assess kidney function?

• A. Complete blood count (CBC)
• B. Blood sugar test
• C. Urinalysis
• D. Creatinine clearance test

Correct answer: D

Rationale: The correct answer is D: Creatinine clearance test. This test is commonly used to assess kidney function by measuring how well the kidneys are filtering waste products like creatinine from the blood. Creatinine is a waste product produced by muscles and is normally filtered out by the kidneys. A high level of creatinine in the blood can indicate reduced kidney function. Options A, B, and C are not specifically used to assess kidney function. A complete blood count (CBC) measures different components of the blood like red blood cells, white blood cells, and platelets. A blood sugar test is used to measure glucose levels in the blood. Urinalysis is a test that analyzes the urine for various substances like proteins, glucose, and blood cells, but it is not the primary test for assessing kidney function.

5. Based on the information provided, which statement is LEAST likely to be supported by the author?

• A. Energy storage technologies play a critical role in the future of renewable energy utilization.
• B. Smart grids can improve the reliability and efficiency of the electricity grid.
• C. Continued reliance on fossil fuels hinders long-term climate change mitigation goals.
• D. Technological advancements offer solutions to overcome challenges associated with renewable energy.

Correct answer: B

Rationale: While the passage mentions smart grids, its primary focus is on managing the intermittency of renewable energy, making B the least likely statement the author would strongly support.

6. What is the scientific name for the kneecap?

• A. Patella
• B. Femur
• C. Tibia
• D. Fibula
