Final answer:
Growth Hormone regulates growth and development, Thyroxin controls metabolism, Insulin regulates blood sugar levels, Adrenaline triggers the fight-or-flight response, and Testosterone promotes male reproductive development.
Step-by-step explanation:
Growth Hormone (GH): Regulates growth and development, stimulates the production of cells and tissues.
Thyroxin: Controls metabolism and energy production in the body.
Insulin: Regulates blood sugar levels by facilitating the uptake of glucose into cells.
Adrenaline: Triggers the fight-or-flight response, increasing heart rate and blood flow.
Testosterone: Promotes the development of male reproductive organs and secondary sexual characteristics.
