Reacts

To behave in a particular way or show a certain response to something, such as a stimulus, an action, or a situation. This can involve a physical or emotional response, a change in behavior, or a chemical process. The nature of the reaction depends on the initial situation and the individual or substance involved. It implies a cause-and-effect relationship, where an external force or event triggers a subsequent response. Reactions can be immediate or delayed, subtle or dramatic, and can range from simple reflexes to complex emotional responses or chemical interactions. Furthermore, this action takes place in many domains, from the biological to the psychological.
