the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

c is the answer to this question. altitude affects the weather because air molecules evaporate.
