Answer 1

Heavy breathing and rapid heart beating can help an organism in a harmful or scary situation/environment by preparing the body for a fight-or-flight response. This response is an automatic physiological reaction that occurs when an organism perceives a threat. It is characterized by increased heart rate, increased respiration rate, increased blood pressure, and increased adrenaline production. These physiological changes help the organism to respond quickly and effectively to the perceived threat.
