Match the hormones given in column I with their functions given in column II: Hormones Functions (i) Thyroxine (a) Causes breasts to develop in females. (ii) Adrenaline (b) Causes the male to start producing sperms. (iii) Insulin (c) Prepares the body for an emergency. (iv) Oestrogen (d) Controls the metabolic rate. (v) Testosterone (e) Regulates the amount of sugar in blood.

(i) - (d) Thyroxine is a hormone secreted by the thyroid gland of the body. It plays an important role in the regulating metabolic rate, digestion, heart and muscle function, etc. (ii) - (c) Adrenaline is a hormone secreted by the adrenal gland of the body. They are present above the kidneys and play an important role during the fight or flight response. (iii) - (e) Insulin is a hormone secreted by the pancreas. It plays an important role in controlling the sugar level in blood. (iv) - (a) Oestrogen is the primary sex hormone, which is secreted by the ovaries in fema les. It plays an important role in the development of the female reproductive system and secondary sexual characteristics. (v) - (b) Testosterone is the male hormone secreted by the testicles. It stimulates the production of sperms in males and also plays a key role in developing sexual characteristics in males. Hormone Function (i) Thyroxine (d) Controls the metabolic rate. (ii) Adrenaline (c) Prepares the body for an emergency. (iii) Insulin (e) Regulates the amount of sugar in blood. (iv) Oestrogen (a) Causes breasts to develop in females.
