Matching Responses and Stimuli
lora16 [44]

Answer:

smelling rotten eggs - covering your nose

touching a hot dish - pulling your hand away

jumping into a cold pool - shivering

Explanation:

<u>A stimulus generally refers to a detectable change in the environment of an organism. These changes could be physical or chemical and could be in the internal or external environment of organisms. </u>

Organisms react to changes in their internal or external environment by responding appropriately. Hence perceiving the smell of rotten egg, feeling the hotness of a dish by touching it, and feeling cold immediately one jumps into a cold pool are all examples of stimuli and their corresponding responses would be covering one's nose, pulling the hand away, and shivering of the body in order to counter the cold.

In other words:

<em>smelling rotten eggs - covering your nose</em>

<em>touching a hot dish - pulling your hand away</em>

<em>jumping into a cold pool - shivering</em>
