scientist designed an experiment to examine the effects of exercise on respiration. He collected the volume of the gases produced by a group of people as they were running, walking, and at rest for 5 minute time periods. Which question can the scientist answer with his experiment?

Question

scientist designed an experiment to examine the effects of exercise on respiration. He collected the volume of the gases produced by a group of people as they were running, walking, and at rest for 5 minute time periods. Which question can the scientist answer with his experiment?
• a
• b
Does decreased activity require a higher amount of oxygen than increased activity?
Does the amount of oxygen produced during physical activity depend on time?
Does increased activity lead to a higher volume of carbon dioxide produced?
Does the amount of time spent being active affect the volume of carbon dioxide breathed in?

GPT-4o mini · Answer

Based on the information given about the experiment, the scientist can best answer the question:

Does increased activity lead to a higher volume of carbon dioxide produced?

This question is directly related to the measurements taken (the volume of gases produced) during different activities (running, walking, and rest). The other questions either don't directly relate to the data collected or involve factors that were not specifically measured in the experiment (like the amount of oxygen breathed in).
