Solution:
Ureters in frog
The elimination of nitrogenous wastes in frog is carried out by a well developed excretory system.The excretory system of frogs are formed of a pair of kidneys,ureters, cloaca and urinary bladder.In male frogs,two ureters come out from the kidney.The ureters act as urinogenital duct and opens into the cloaca.In female frogs the ureters and oviduct open separately into the cloaca.
Malpighian tubules
Malpighian tubules are the excretory organs of cockroaches.They are a ring of 100-150 yellow coloured thin filamentous structures present at the junction of midgut and hindgut which help in removal of excretory products from haemolymph.
Body wall in earthworm
The body wall of the earthworm is covered by a non-cellular cuticle.It is formed of two muscle layers.These layers help in movement of the earthworm.
