Answer
Reflex response helps to keep organisms alive by quickening their reaction times when in danger instead of having to think about what they need to do
Step-by-step explanation:
Think about your friend throwing something at your face. What do you do- you probably cover up your face, or try to move out of the way. This is a reflex, and it saves your face from pain. While this is a silly example, these type of automatic "reflex" reactions are absolutely vital in the wild. Mice have the reflex to run when a they see or hear what they think is a predator. This give them the precious seconds they need to escape certain death. Say they didn't move on reflex. If they instead sat and thought about what they needed to do, the predator would catch them and they would die.
