A hot spot is an area in the mantle of the earth where heat increases during the convection phase. This heat makes it easier for rock to melt. The melted lava, known as magma, drives volcanoes into cracks in the crust. There was a mistake. It does happen instead in abnormally hot centers called mantle feathers.
The answer to this question is Neurotransmitter
Neurotransmitter will create a chemical change inside our body as a response to each situation that we face. This response then will be transmitted toward our body and will determine what we should do next, (this process will be a lot easier to observe during dangerous fight or flight situations)
