Life Processes of Humans: Response to Stimuli

Response to Stimuli: What do you do if you accidentally touch a hot object or the thorn of a rose? You will move your hand away from the hot object or the thorn immediately! The hot object or the thorns are examples of stimuli. The sudden movement of the hand away from the stimuli is called response.

Humans Reproduce: Humans reproduce by giving birth to their offspring. This process continues from one generation to another. When humans reproduce, the number of people increases.
