• C. i.Adrenaline ii.Noradrenaline iii.Medulla iv. Cortex v. Glucocorticoids vi. Mineralocorticoids
• D. i.Mineralocorticoids ii.Adrenaline iii.Noradrenaline iv. Medulla v. Cortex vi. Glucocorticoids

Answer 1

The correct option is A

i. Medulla ii.Cortex iii.Glucocorticoids iv. Mineralocorticoids v. Adrenaline vi. Noradrenaline

Adrenal cortex; This part of adrenal gland is very important for the animal and its removal or destruction will kill the animal. It produces mainly two groups of steroid hormones (i) Glucocorticoids and (ii) Mineralocorticoids

Adrenal medulla; It helps the body to prepare for stress or any emergency conditions. This part of adrenal, unlike cortex, is not so vital for the survival of the organism and so its removal will not cause death.It produces two hormones called as adrenaline or epinephrine and noradrenaline or norepinephrine.
