How does the body maintain homeostasis on a hot day?

Through Sweating

Explanation:Sweating means particles with lots of energy evaporate this has a cooling effect on the body as the particles have a lower kinetic energy are left. Furthermore skin does vasodilation and vasoconstriction  this talks about blood vessels dilating and constricting to allow blood flow to move in and out of the body. The skin is a receptor and it detects the weather/stimulus through the blood which goes through the hypothalamus. The hypothalamus controls homeostasis in the body

carbon atoms, hydrogen, oxygen, and nitrogen.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
