Question

the nerve cells in a chef’s hand sense heat from a pan. the nerve cells send signals to the chef’s brain. the brain sends signals to the hand to release and drop the pan.
which characteristic of living things does the action of the chef best demonstrate?

○ the ability to respond to a stimulus
○ the ability for evolutionary change
○ the ability to grow and develop
○ the ability for cells to contain dna

Explanation:

The chef's hand senses heat (a stimulus), nerve cells send signals to the brain, and the brain signals the hand to drop the pan (a response). This matches the ability to respond to a stimulus. Evolutionary change, growth/development, and cell DNA containment are not demonstrated here.

Answer:

the ability to respond to a stimulus
