$(a)$ Draw the structure of a nephron and label the following on it: Glomerulus,Bowman's capsule,Renal artery,Collecting duct.
$(b)$ What happens to glucose that enters the nephron along with the filtrate?

(N/A) The structure of a nephron is shown in the figure. The key parts are the Glomerulus (a cluster of capillaries),Bowman's capsule (a cup-shaped structure surrounding the glomerulus),the Renal artery (which brings blood to the nephron),and the Collecting duct (which collects urine from various nephrons).
$(b)$ When blood is filtered through the glomerulus,substances like glucose,amino acids,salts,and water enter the Bowman's capsule as part of the filtrate. As this filtrate moves through the tubular part of the nephron,useful substances like glucose are selectively reabsorbed back into the blood capillaries surrounding the tubule.
