Read the following scenario and answer the questions that follow.   Scenario:  You are conducting a series of experiments on the elusive pink and green snaggle-toothed rodent.  They don’t live very long, so you are trying to find out as much about them as possible as quickly as you can.  You are housing each of them in their own cage, but in the same climate-controlled room.  You are feeding them the same, highly nutritious food.  Today, you are conducting experiments on them that involved respiration and exercise.   You have them run on a little treadmill that you designed especially for them.  Each of them ran on the little treadmill for 5 minutes.   The data that you collected today was added to your data table, which now contains the following data:  age, sex, if they were fed or not (one (1) hour before exercising), their average resting heart rate, and their average heart rate immediately after exercising.     A:  What is your purpose for this research “today”?  (What were you trying to determine?)  B:  Write a good hypothesis for today’s study.
