Answer 1

Answer: (D)

Frogs are ureotelic, i.e., they excrete urea as their nitrogenous waste. Two olfactory lobes are present in the forebrain of frog. They have renal portal system in which the blood from the hind parts of the body goes into post caval and then to the heart after getting filtered in the kidneys. Lymphatic system of frogs comprises of lymph, lymph capillaries, lymph sinuses and lymph heart. Liver secretes bile which is transferred to the gall bladder for storage through many hepatic ducts.
