1. Populations can have variety, despite being made up of the same species. If a population has different expressed traits, this can be due to different inherited alleles. Genetic drift can cause a change in allele frequency in a population. What if
you had to explain genetic drift to a friend who has not watched the video? Use the comics below in your narration of
genetic drift. Refer to comic A, comic B, and comic C in your narrative. You can use the comics in any order you choose!

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.
