Question
Part of the goal for this portfolio is to practice using the scientific method. Step 1 of this method is to develop a research question. For this investigation, your question will be something like: how does the human body maintain homeostasis before, during, and after physical exercise?
Step 2 of the scientific method is to develop a hypothesis, which is a guess as to what your investigation will show you. Which of the following would be an appropriate hypothesis for the research question above?
(1 point)
Responses
If a human has homeostasis, then they will do physical exercise.
If a human has homeostasis, then they will do physical exercise.
If a human does physical exercise, then they will have a heart rate.
If a human does physical exercise, then they will have a heart rate.
If a human does physical exercise, their heart rate will change in order to maintain homeostasis.

The most appropriate hypothesis for the research question "How does the human body maintain homeostasis before, during, and after physical exercise?" is:
**"If a human does physical exercise, their heart rate will change in order to maintain homeostasis."**
This hypothesis clearly relates to the investigation of how the body responds to physical exercise in terms of maintaining homeostasis, specifically focusing on the role of heart rate.
**"If a human does physical exercise, their heart rate will change in order to maintain homeostasis."**
This hypothesis clearly relates to the investigation of how the body responds to physical exercise in terms of maintaining homeostasis, specifically focusing on the role of heart rate.
