Match the Hormones listed in Column I with their characteristics listed in Column II No. Hormone No. Characteristics A Adrenal Cortex P Mediates responses to external stimuli. B Epinephrine Q Steroid hormone. C Estrogen R Iodinated derivative of Tyrosine amino acid. D Thyroxine S Its malfunction causes Addison's disease.

Step-by-step solution

Adrenal cortex produces steroid hormones like cortisol and aldosterone. Malfunction or hyposecretion of the adrenal cortex leads to Addison's disease. Thus, A matches with S. Epinephrine is a catecholamine hormone secreted by the adrenal medulla that mediates rapid responses to external stimuli, often referred to as the fight-or-flight response. Thus, B matches with P. Estrogen is a primary female sex hormone and is classified as a steroid hormone. Thus, C matches with Q. Thyroxine is an iodinated derivative of the
