An experiment to measure the rate of respiration in crickets and mice at 10C and 25C was performed using a respirometer, an apparatus that measures changes in gas volume. Respiration was measured in mL of 02 consumed per gram of organism over several five-minute trials and the following data were obtained. Organism Temperature (°C) Average respiration (mL O,/g/min) Mouse 10 0.0518 Mouse 25 0.0321 Cricket 10 0.0013 Cricket 25 0.0038 12. During aerobic cellular respiration, oxygen gas is consumed at the same rate as carbon dioxide gas is produced. In order to provide accurate volumetric measurements of oxygen gas consumption, the experimental setup should include which of the following? (A) A substance that removes carbon dioxide gas (B) A plant to produce oxygen (C) A glucose reserve (D) A valve to release excess water 13. According to the data, the mice at 10C demonstrated greater oxygen consumption per gram of tissue than did the mice at 25C. This is most likely explained by which of the following statements? (A) The mice at 10C had a higher rate of ATP production than the mice at 25C. (B) The mice at 10C had a lower metabolic rate than the mice at 25C. (C) The mice at 25C weighed less than the mice at 10C. (D) The mice at 25C were more active than the mice at 10C.

12. During aerobic cellular respiration, oxygen gas is consumed at the same rate as carbon
dioxide gas is produced. In order to provide accurate volumetric measurements of oxygen gas
consumption, the experimental setup should include which of the following?
(A) A substance that removes carbon dioxide gas
(B) A plant to produce oxygen
(C) A glucose reserve
(D) A valve to release excess water
13. According to the data, the mice at 10C demonstrated greater oxygen consumption per gram
of tissue than did the mice at 25C. This is most likely explained by which of the following
statements?
(A) The mice at 10C had a higher rate of ATP production than the mice at 25C.
(B) The mice at 10C had a lower metabolic rate than the mice at 25C.
(C) The mice at 25C weighed less than the mice at 10C.
(D) The mice at 25C were more active than the mice at 10C.
14. According to the data, the crickets at 25C have greater oxygen consumption per gram of
tissue than do the crickets at 10C. This trend in oxygen consumption is the opposite of that in the
mice. The difference in trends in oxygen consumption among crickets and mice is due to their
(A) relative size
(B) mode of nutrition
(C) mode of internal temperature regulation
(D) mode of ATP production
15. Experimental evidence shows that the process of glycolysis is present and virtually identical
in organisms from all three domains, Archaea, Bacteria, and Eukarya. Which of the following
hypotheses could be best supported by this evidence?
(A) All organisms carry out glycolysis in mitochondria.
(B) Glycolysis is a universal energy-releasing process and therefore suggests a common ancestor
for all forms of life.
(C) Across the three domains, all organisms depend solely on the process of anaerobic
respiration for ATP production.
(D) The presence of glycolysis as an energy-releasing process in all organisms suggests that
convergent evolution occurred.,
