15 points and will mark brainliest! our body temperature will stay around 98.6 degrees, even when it is hot or cold outside. this is an example of: a. a behavioral adaptation b. structural adaptation c. homeostasis d. equilibrium

Option C, Homeostasis

Explanation:

Homeostasis is a mechanism through which body maintain its state of stability/equilibrium. Thermoregulation is one of the mechanism of homeostasis by which body maintain its internal temperature. The average human body temperature is 98°F (37°C). When the external temperature increases, the body sweats or vassolidate to maintain the stable temperature.

When the external temperature decreases, the body undergo vasoconstriction or thermogenesis to main its average temperature.

Hence, option C is correct

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.
