Renal artery obviously transports glucose. When filtered, it is reabsorbed back into the renal vein, so there is no presence of glucose in the ureter.

Dunno about the second one, can someone help please?
And for last one, yes A, but what's the development shown?

Ivo only urine isn't excretion ;D. Excretion includes removal of waste products of metabolism and Carbon Dioxide is a waste material. Development is increase in complexity by cell enlargement, cell division and morph genesis. I think it's development cause you've got new leaves in it which must have developed from the shoot. Anyway, VIN please (oh wait you're intoxication now ;D) please help. I ain't too confident of that....
