What do you notice about the net charges of the balloon and the hair after electric charges moved
between them?

The friction between the them after you rub them together becomes weaker

Explanation:

It is you static of your skin and the rubber of the ballon give it the friction to stick together if you still do not understand here is simpler way its energy from the hand Ballon and skin if you still do not understand theni do not know what to tell but that my answer

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.
