Question

Shreya touched a hot kettle and quickly pulled her hand away. Which characteristic is proved by the given statement?

• A. Response to stimuli
• B. Growth
• C. Reproduction
• D. Respiration

Answer 1

The correct option is A

Response to stimuli

Living things respond to changes around them. Response to stimuli is one main characteristic of all living things including plants. For example, the touch-me-not plant (Mimosa pudica). The leaves of this plant close or droop in response to touch. In humans and higher mammals, there is a separate nervous system which helps to sense stimulus and send signals to the brain to respond in the appropriate way to that stimulus. Therefore, Shreya pulled her hand away when she touched a hot kettle in response to touch.
