Jonathan is learning about water conservation. he learns that the average household in the united states uses 293 gallons of water per day. jonathan makes a chart that shows the percent of water that each indoor fixture uses in the average u. s. household. he would like to use this chart to determine which indoor fixture uses the most water in his own home. then, he can replace this fixture with a more efficient, water-saving fixture. what would be an appropriate research question to guide jonathan's research project? a) how can we use less water at home? b) how can the united states conserve water? c) which fixture uses the most water in our home? eliminate d) do shower heads use more water than sink faucets?

Option C, Which fixture uses the most water in our home? Eliminate

Explanation:

The overall agenda of Jonathan's experiment is to conduct an experiment through which he will try to identify the fixture which causing the maximum water loss and then this fixture will be replaced with an efficient fixture to reduce water wastage.

Thus, once the agenda is clear, the most appropriate question among the given options would be option (C) Which fixture uses the most water in our home? Eliminate

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.
