Deep beaks have benefits, but they also have disadvantages. finches with deep beaks require more food and are less likely to survive the juvenile period than finches with shallow beaks. after the drought subsided on daphne major, what is likely to have happened to the average beak depth of the next generation?

The correct answer is that the beaks would increase - this is the adaptation of finches to the new conditions (drought).

Beak depth varies according to drought conditions. Since after the drought vegetation dries out and the hard, big, tough seeds remain, only the finches with deep beaks will survive. Finches adapt via their beaks to different foods sources and different local conditions.

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.
