Excretory Products and Their Elimination(NCERT)

Uric acid is nitrogenous waste in
1 Birds and lizards
2 Mammals and molluscs
3 Frog and cartilaginous fishes
4 Insects and bony fishes
Explanation:
(b) The excretion of uric acid as nitrogenous waste is called uricotelism. The excretion of uric acid is advantageous for those animals which have to conserve water for their survival like birds and lizards.

A fall in glomerular filtration rate (GFR) activates
1 adrenal cortex to release aldosterone.
2 adrenal medulla to release adrenaline.
3 juxta - glomerular cells to release renin.
4 posterior pituitary to release vasopressin.
Explanation:
(c) The amount of the filtrate formed by the kidneys per minute is called glomerular filtration rate (GFR). GFR in a healthy individual is approximately $125\text{ml}/$ minute, i.e., 180 litres per day. A fall in GFR can activate the JG cells to release renin which can stimulate the glomerular blood flow and thereby the GFR back to normal. Renin converts angiotensinogen in blood to angiotensin I and further angiotensin II. Angiotensin II being powerful vasoconstrictor increases the glomerular blood pressure and thereby GFR.
(b) The excretion of uric acid as nitrogenous waste is called uricotelism. The excretion of uric acid is advantageous for those animals which have to conserve water for their survival like birds and lizards.
