Stale urine smells like ammonia because

$A$: Pregnant women may show some presence of glucose in their post-prandial urine although they have no diabetes.

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

Match the following:
$A$. Loop of Henle: $1$. Carries blood into the kidney
$B$. Renal artery: $2$. Area where a considerable amount of reabsorption takes place
$C$. Proximal convoluted tubule: $3$. Main area of secretion
$D$. Glomerulus: $4$. Filtration of blood
$E$. Distal convoluted tubule: $5$. Plays a role in concentration of urine
The correct pairing sequence is:

Consider the following water conservation mechanisms:
$A.$ Nasal countercurrent mechanism
$B.$ Dependence on metabolic water
