The term for changes in the internal or external environment that cause a response is stimuli.

The correct term for changes in the internal or external environment that cause a response is stimuli. To arrive at this answer, you can break down the options and identify that the term should describe the changes that trigger a response. "Responses" refers to the actual reactions or actions resulting from these changes, rather than the changes themselves. "Signals" and "messages" refer more to the delivery of information rather than the changes in the environment. "Nerves" are part of the nervous system and play a role in transmitting signals, but they are not the term for the changes themselves. Therefore, "stimuli" is the appropriate term for this concept.
