Reptiles are ectothermic yet they must still be able maintain a relatively high internal body temperature in order to function properly. because reptiles do not have an internal thermoregulation mechanism, they must rely on external mechanisms. all but one would a reptile increase body temperature. that is a) movement. b) hibernation. c) basking in the sun. d) eating and digestion.

It should be C. Reptiles are cold blooded and rely on the sun rather homeostasis or self metabolism to heat up. Hope this helps!! :D

answer; (phospholipid);

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.
