An individual who participates in a long-distance run on a hot day will produce large quantities of sweat. As a result of the
excessive sweating, the amount of urine produced by the
kidneys will change.
How will the kidneys respond to help the individual's body
maintain homeostasis?

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

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 farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
