Diuresis is a condition characterized by:

Match the following columns:

Column-$I$	Column-$II$
$a.$ Loop of Henle	$1.$ Carries blood to the kidney
$b.$ Renal artery	$2.$ Region where maximum reabsorption occurs
$c.$ Proximal Convoluted Tubule $(PCT)$	$3.$ Main site of secretion
$d.$ Glomerulus	$4.$ Filtration of blood
$e.$ Distal Convoluted Tubule $(DCT)$	$5.$ Plays a significant role in urine concentration

The correct sequence is:

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.

$A$: Pregnant women may show some presence of glucose in their post-prandial urine although they have no diabetes.
$R$: In pregnant women,the glomerular filtration rate $(GFR)$ is slightly increased. As a result,the tubular load of glucose exceeds the tubular maximum for glucose reabsorption.

$A$: Birds have metanephric kidneys and no urinary bladder.
$R$: South American Ostrich has a urinary bladder.

Why do we urinate more frequently during cold and humid weather?
