Answer:
here.
Explanation:
Homeostasis is keeping internal body conditions near constant.
Now let's apply this to cleaning our room:
for example, if it's a mess, no one will really tolerate inhabiting it. Same with our body. For our bodies to function, everything needs to be ordered, all the chemical reactions need to happen at a certain rate at a certain time.
Let's for example talk about your room's temperature, if it gets too hot, you're going to switch on the fan and if it gets too cold, you'll hide under a blanket. And you will do this so that you're comfortable enough to carry on with what you do.
Same for our body, if it gets too hot, your body, via negative feedback, will be able to lower it's temperature such that the chemical reactions, keeping you alive, occur at an appropriate rate without enzyme denaturation.
Cleaning up your room from all the dirt is like excreting all the waste products that gives your body a healthy balance. Eg: the carbon dioxide you excrete when you breathe out is important because if it remains in your blood, the blood's ph will drop, which'll affect the rate of chemical reactions. Similarly if the dirt in your room accumulates it's going to smell bad.
