Final Answer:
The easiest example of homeostasis to measure without complicated or expensive equipment would be C. A person exercises, and their body temperature increases; their heart rate increases to pump blood around the body faster and dissipate the heat more.
Step-by-step explanation:
C.Measuring the physiological response to exercise involves readily accessible and simple parameters. In this scenario, monitoring heart rate and body temperature can be achieved using basic tools like a stopwatch and a thermometer. The relationship between increased heart rate and elevated body temperature is a straightforward indicator of the body's attempt to maintain homeostasis during physical activity.
Heart rate, measured in beats per minute (bpm), reflects the cardiovascular response to exercise. An increase in heart rate is a direct adaptation to the body's need for enhanced oxygen and nutrient delivery to active muscles. Similarly, body temperature, measured in degrees Celsius (°C), rises during exercise due to increased metabolic activity. These measurable changes provide a practical and uncomplicated means of quantifying homeostasis without the need for specialized equipment.
By choosing the physiological response to exercise as the parameter for homeostasis measurement, one can easily and cost-effectively gather data to understand how the body maintains balance during a common and easily replicable activity. This simplicity makes it an ideal choice for experiments without the need for sophisticated instrumentation.
