Question

an experiment to measure the rate of respiration in crickets and mice at 10°c and 25°c was performed using a respirometer, an apparatus that measures changes in gas volume. respiration was measured in ml of o₂ consumed per gram of organism over several five - minute trials, and the following data were obtained. according to the data, the mice at 10°c demonstrated greater oxygen consumption per gram of tissue than did the mice at 25°c. this is most likely explained by which of the following statements? the mice at 10°c had a higher rate of atp production than the mice at 25°c. the mice at 10°c had a lower metabolic rate than the mice at 25°c. the mice at 25°c weighed less than the mice at 10°c. the mice at 25°c were more active than the mice at 10°c.

Explanation:

Step1: Analyze the data for mice

For mice, the average respiration (oxygen consumption per gram of organism per minute) is 0.0321 mL O₂/g/min at 25°C and 0.0518 mL O₂/g/min at 10°C.

Step2: Interpret the meaning of higher oxygen - consumption

Higher oxygen - consumption indicates a higher metabolic rate as ATP production is related to cellular respiration which consumes oxygen. Since mice at 10°C have a higher rate of oxygen consumption, they have a higher rate of ATP production compared to mice at 25°C.

Answer:

The mice at 10°C had a higher rate of ATP production than the mice at 25°C.
