Answer:
Epinephrine
Explanation:
Epinephrine, which is also referred to as adrenaline, is the active sympathetic hormone that is secreted by the medulla of the adrenal glands into the bloodstream to initiate the body’s fight-or-flight response to stress or threat, causing increased blood pressure, sugar metabolism, heart rate, breathe rate, muscle strength as well as sweat. Pete's sighting of a bear as a threat stimulates the sympathetic nervous system to initiate the secretion of epinephrine which brings about the fight-or-flight response of the body to increase alertness of the body.
