Answer:
C. The mouse started running.
Explanation:
When an organism begins an activity that has the power to burn off its body fat through energy expenditure, that fat is first released into the lungs as carbon dioxide. The more intense the activity the more carbon dioxide will be released by the body.
Based on this, we can state that carbon dioxide production in a mouse increases as it begins to flow. This is because the mouse begins to expend energy, which will burn off the fat in your body, which will be released by the lung in the form of carbon dioxide.
