The reaction to something in an environment is called a stimulus.
it's actually a natural reaction of the body, when you respond you respond to that something, the body isn't responding to it it is reacting because of the environment. do you understan?
An endothermic reaction is what increases solubility. When something is heated, and then continues moving (being mixed) it creates a better environment for an endothermic reaction.
Contact dermatitis is usually due to an allergic reaction to something in the environment. This allergen will come "in contact" with the skin, producing an allergic reaction, usually a rash that is itchy and red.
reflex
An endothermic reaction absorbs energy, making its environment cooler. Ab exothermic reaction releases energy, making its environment warmer.
yes, something rotting is a chemical reaction because it undergo oxidation reaction. the reaction is a part of redox reaction
The temperature in addition to the pH sacle of something in particular in the environment would affect the rate of speed of an enzyme and would slow down the reaction if it is too high.
tropism
an endothermic reaction is any chemical reaction that absorbs heat from its environment.
This depends on this "something".
A stimulus.
