According to the data, the crickets at 25oC have greater oxygen consumption per gram of tissue than do the crickets at 10oC. 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

C. mode of internal temperature regulation.

Explanation:

Crickets and mice both have different mode of their internal temperature regulation that's why their body produces energy (ATP) and act better on particular temperature.

Mice have higher rate of ATP production at 10 degree C than the mice 25 degree C while the crickets are most efficiently produce energy (ATP) at 25 degree C than 10 degree C.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
