In homeostatic regulation, a variable refers to what?

• A. A measurable factor such as body temperature or heart rate that is regulated
• B. A bone or organ
• C. A gene
• D. A nerve

Answer: (A)

In homeostatic regulation, the variable is the measurable factor that the body keeps within a narrow range. It’s the value the body monitors and adjusts, such as body temperature or heart rate. The system uses sensors to detect changes, a control center to process them, and effectors to bring the variable back toward its set point. This makes the variable a dynamic, regulatable parameter, not a bone or organ, a gene, or a nerve.
