Suppose you have been doing heavy yardwork on a hot day and sweating profusely.You become very thirsty, so you drink a tallglass of lemonade. Explain how your thirstrelates to the concept of homeostasis. Whichtype of feedback—positive or negative—does this illustrate?
When you step outside in the cold, your body temperature decreases; which causes shivering or contractions of your muscles. In this example, the shivering or contracting of the muscles, is what part of the feedback loop?
Is this an example of positive or negative feedback?
