Asked by Void<3
Two girls on a track team recorded their heart rates before, during and after a short exercise.
Use the graph below and what you know about the human body and homeostasis to answer the questions that follow.
Explain how the graph demonstrates homeostasis with at least 3 sentences. Be sure to include specific data from the graph. (4 points)

I can’t see the graph you mentioned — could you upload it or type the heart-rate values (resting, peak during exercise, and after exercise) for each girl? With that I’ll write a precise 4‑point answer using the exact numbers.
Meanwhile, here is a ready-to-use 4‑sentence answer you can adapt by plugging in the numbers from your graph, plus an example filled with numbers:
Template (replace bracketed text with values from your graph):
- “Before exercise Girl 1’s heart rate was [resting1] beats per minute (bpm) and Girl 2’s was [resting2] bpm. During the run their heart rates rose to [peak1] bpm and [peak2] bpm, respectively, showing increased cardiac output to meet muscle oxygen demands. After the exercise their heart rates fell to [recovery1] bpm and [recovery2] bpm within [time] minutes, demonstrating homeostasis as the body returned toward its resting state. This return toward baseline is controlled by negative‑feedback mechanisms (parasympathetic activation and reduced sympathetic input) that restore internal conditions after a disturbance.”
Example (if your graph shows these numbers):
- “Before exercise Girl 1’s heart rate was 68 bpm and Girl 2’s was 72 bpm. During the run their heart rates rose to 150 bpm and 162 bpm, respectively, showing increased cardiac output to meet muscle oxygen demands. After the exercise their heart rates fell to 80 bpm and 84 bpm within 3 minutes, demonstrating homeostasis as the body returned toward its resting state. This return toward baseline is controlled by negative‑feedback mechanisms (parasympathetic activation and reduced sympathetic input) that restore internal conditions after a disturbance.”
Send the actual values or the graph and I’ll produce the exact answer tailored to your data.
