Answer:
Cortisol, having many good friends calms the hypothalamus-pituitary-adrenal axis
Explanation:
People with high social support show lower baseline levels of <u>cortisol</u>, which suggests that having many good friends <u>calms the hypothalamus-pituitary-adrenal axis</u> which is activated in fight and flight.
