Stale urine smells like ammonia because

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:

Substance	Glomerular filtrate	Reabsorbed	Urine
$(i)$ Proteins	$2 \,g$	$1.9 \,g$	$0.1 \,g$
$(ii)$ Glucose	$162 \,g$	$162 \,g$	$0 \,g$
$(iii)$ Urea	$54 \,g$	$24 \,g$	$30 \,g$
$(iv)$ Creatinine	$1.6 \,g$	$0 \,g$	$1.7 \,g$

$(a)$ Glucose is completely reabsorbed.
$(b)$ Urea is partially reabsorbed.
$(c)$ Proteins are secreted into urine.
$(d)$ Creatinine is secreted into urine.
Which of the following options,in view of the above statements,is correct?

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.

Which of the following is $NOT$ a function of the kidney?

In the urinogenital organs of a rabbit,which one of the following parts is present in the male but not in the female?
