Question

what are stimulus and reaction? Give some examples.​

Answer 1

The simplest type of response is a direct one-to-one stimulus-response reaction. A change in the environment is the stimulus; the reaction of the organism to it is the response.

Answer 2

Answer:

Stimulus: any change in an organism's environment that causes the organism to react. It is a fancy way of saying “cause”. Example: An animal is cold so it moves into the sun.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. Log burning in a fire. Burning wood is an example of a chemical reaction in which wood in the presence of heat and oxygen is transformed into carbon dioxide, water vapour, and ash.
