In which of the following animals kidneys are aglomerular ?

Resorption of water and electrolytes by distal tublules of kidney and thereby diuresis reducing the loss of water through urine (diuresis) is done by

Resorption of water and electrolytes by distal tublules of kidney and thereby diuresis reducing the loss of water through urine (diuresis) is done by

A: Tubular secretion is of considerable importance in larine teleost fishes. R: These have aglomerular kidney i.e., no fitration occurs and tubular secetion is the only way of excertion.

Assertion: Vasopressin is also called anti-diuretic hormone (ADH) Vasopressin acts mainly at the kidney and stimulates resorption of water and electrolytes by the distal tubules and thereby reduces the loss of water through urine (diuresis).
