Assertion: Secreting hypotonic urine is effective in reducing urinary loss of water.
Reason: Hypotonic urine is more concentrated and higher in osmotic pressure than the blood.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(d) If both the Assertion and Reason are incorrect.
Explanation:
Hypotonic urine means concentration of urine is less than that of blood. Hypertonic urine is more concentrated than blood and has high osmotic pressure than the blood, therefore it helps in reducing the loss of water with urine. The urine is filtered by the Bowman's capsule. The tubules of nephrons reabsorb a large quantity of water making urine more concentrated.
