The hormone that dominate during the alarm phase of the general adaptation syndrome gas is?

The hormone that dominates during the alarm phase of the general adaptation syndrome (GAS) is adrenaline (epinephrine). This phase is characterized by the body's immediate response to stress, triggering the "fight or flight" response. Adrenaline increases heart rate, blood pressure, and energy supplies, preparing the body to react to the perceived threat. Other stress hormones, such as cortisol, also play a role but are more prominent in later phases.
