Saadat is walking to the front of the classroom in preparation for his class presentation. he notices his heart starting to beat fast, his palms are sweaty, and has a general sense of increase in energy. according to the general adaptation syndrome, which phase of the stress response is he in?

The answer is "alarm phase".

The alarm stage is otherwise called the fight or flight response. During this stage, your brain sends a crisis flag to different parts of your body, which tells those parts that you're in a perilous circumstance. As your body activates itself to respond, you can pick between a battle or flight reaction. For instance, you'd be picking the 'battle' reaction in the event that you heard discharges on a city road and defied the shooter. By examination, you'd be picking the 'flight' reaction in the event that you fled the scene, which as per your mind, would undoubtedly be to your greatest advantage.
