4 More water reabsorption due to undersecretion of ADH
Explanation:
(a) Adrenal cortex secretes mineralocorticoids like aldosterone which increase the reabsorption of $\text{Na}+$ and water from renal tubule that prevent diuresis. Diuresis is a condition in which the kidneys filter too much bodily fluid.

The function of renin
1 degradation of angiotensinogen
2 stimulation of corpus luteum
3 to reduce blood pressure
4 vasodilatation
Explanation:
(a) Renin converts angiotensinogen in blood to angiotensin I and further to angiotensin II (a vasoconstrictor).

Volume of urine is regulated by
1 aldosterone
2 aldosterone and $\text{ADH}$
3 aldosterone, $\text{ADH}$ and testosterone
4 $\text{ADH}$ alone
Explanation:
(b) Aldosterone and ADH maintains the volume of urine. Aldosterone, produced by the adrenal cortex, causes the retention of water in the body by increasing the levels of sodium and potassium ions in the blood, which causes the body to reabsorb more water. Antidiuretic hormone (ADH) produced by the hypothalamus and released by the posterior pituitary, causes more water to be retained by the kidneys when water levels in the body are low.

The hormone that promotes reabsorption of water from glomerular filtrate is
1 oxytocin
2 calcitonin
3 vasopressin
4 relaxin
Explanation:
(b) Vasopressin promotes reabsorption of water from the glomerular filtrate. Vasopressin, also known as antidiuretic hormone (ADH), is a neurohypophysial hormone. It helps to retain water in the body and constrict blood vessels. Vasopressin regulates the body's retention of water by acting to increase water reabsorption in the collecting ducts of the nephron, which is the functional component of the kidney.
