Is this a good scientific question? “is the lifespan of snowshoe hares, which are white in the winter and brown in the summer, affected by levels of winter snowfall? ”

The given question - 'Is the lifespan of the snowshoe hares which are white in winter and brown in summer affected by levels of winter snowfall?' is a good scientific question. This question is very specific about the query. Moreover, the query asked in the question can be answered using the scientific testing methods. A hypothesis can be formed based on the question which can be tested.

Hence, it is a good scientific question.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

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.
