Explanation / Answer
9.2) Negative feedback is a vital control mechanism for the body's homeostasis. You saw an example of a feedback loop applied to temperature and identified the components involved. The body maintains a relatively constant internal temperature to optimize chemical processes.
9.3) Thermoregulation is important to organisms because the bodies of plants and animals function best at specific temperature ranges, and if body temperature slips too far outside its ideal temperature range, the organism will die.
9.4) The kidneys maintain our body's water balance by controlling the waterconcentration of blood plasma. The kidneys also control salt levels and the excretion of urea. Water that is not put back into the blood is excreted in our urine
