Oliver measures his breathing rate while running. Here are his results. Time (minutes) Breathing rate (breaths per minute) 0 12 1 22 2 24 3 26 4 28 5 30 What variable does he change?

Oliver changes the time to compare the breathing rate per minute. At different times, the breathing rate increases. Running makes the heart beat faster as the muscles need more oxygen. To compensate for the need for more oxygen the breathing becomes faster and deeper. So breathing rate would be increased.

He measures the breathing rate at a different time while running. At different times, the breathing rate increases. This is because the muscles need more oxygen so, breathing becomes faster and the breathing rate increases.

Oliver measures his breathing rate while running. Here are his results. Time (minutes) Breathing rate (breaths per minute) 0 12 1 22 2 24 3 26 4 28 5 30 Suggest an explanation for Oliver's results.

Oliver measures the rate of breathing per minute at a different time while running. The result shows that the breathing rate increase as time increases. This is due to the running. Running Makes our heartbeat and breathing rate faster as the muscles work harder and need oxygen at a higher rate so, the hearts need to pump more blood to compensate for the deficiency of oxygen. Heart rate increases to deliver oxygen to the respiring muscles more efficiently.

Complete the word equation for aerobic respiration. _____+oxygen → Carbon dioxide+ _____

Glucose + Oxygen → Carbon dioxide + Water Aerobic respiration is a type of cellular respiration that occurs in the presence of oxygen. It takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy.
