A biology student wanted to see if runners from the track team would have a lower respiratory rate than non-runners during exercise. She determined each student's resting respiratory rate. Each student performed the same exercise for a total of 3 minutes, measuring their respiratory rate at the end of each minute. They continued to measure their respiratory rates for 3 more minutes after the exercising had stopped. The table below shows the average respiratory rate of these students over time. Time Runners Non-runners (minutes) (breaths/min) (breaths/min)Resting respiratory rate 0 14 18Exercise phase 1 18 30 2 20 34 3 24 40Post-exercise phase 4 22 39 5 17 36 6 14 32Which of the following is best supported by the data in the table?A) The non-runners returned to resting respiratory rate faster than the runners. B) The respiratory rates of both groups increased by the same amount during exercise. C) The non-runners had a lower respiratory rate than the runners during exercise. D) The respiratory rates of the runners returned to the resting rate 3 minutes post-exercise.
