Solution

Beard and moustache develop in boys aged 13- LH (Luteinizing hormone) along with FSH help in the secretion of testosterone from testes in males which is responsible for secondary sexual characters.
Oversecretion of growth hormone takes place during childhood- Human growth hormone is responsible for the growth of long bones, muscles and is secreted in a large amount in children.
Increased heartbeat and breathing occurs during any unforeseen situation- release of adrenaline from the adrenal medulla aids the body to deal with stressful situations for quick action.
