How does an organism respond to a stimulus?

It ignores it
It transmits it
It reacts in a pre-determined way
It responds with a change in behavior

The correct answer is: It responds with a change in behavior

An organism responds to a stimulus by reacting with a change in behavior. This allows the organism to adapt to its environment and survive. Option A, ignoring it, would not be a beneficial response as it does not address the stimulus. Option B, transmitting it, is not necessarily a response by the organism, but rather a method of information transfer. Option C, reacting in a pre-determined way, suggests a fixed and unchangeable response, which may not always be the case for organisms. Therefore, option D, responding with a change in behavior, is the most accurate description of how an organism responds to a stimulus.
