In the renal tubule,the reabsorption of chloride ions from the glomerular filtrate occurs by:

Components reabsorbed by passive transport - $P$
Components reabsorbed by active transport - $Q$
$I - Na^+$,$II$ - Glucose,$III$ - Nitrogenous wastes,$IV$ - Amino acids,$V$ - Water
Select the correct option for $P$ and $Q$.
$P \quad \quad Q$

The amount of the original filtrate volume which is reabsorbed by the time the tubular fluid enters the Henle's loop is approximately (in $\%$)

Sodium,water and phosphate reabsorption is maximum in

Part of the nephron where conditional reabsorption of $H_2O$ and $Na^+$ occurs is:

Match the following columns:

Column-$I$	Column-$II$
$a. PCT$	$i. \text{Selective secretion of } H^+ \text{ and } K^+ \text{ ions}$
$b. DCT$	$ii. 70-80\% \text{ of electrolytes and water reabsorption}$
$c. \text{Descending limb}$	$iii. \text{Allows passage of small amounts of urea}$
$d. \text{Ascending limb}$	$iv. \text{Permeable to water}$
$e. \text{Collecting duct}$	$v. \text{Permeable to salts}$
