Question

Which of the following groups have similar function?

• A. Typhlosole in Earthworm, intestinal villi in Rat and contractile vacuole in Amoeba
• B. Nephridia in Earthworm, malpighian tubules in Cockroach and urinary tubules in Rat
• C. Antennae in Cockroach, tympanum of Frog and clitellum of Earthworm.
• D. Incisors of Rat, gizzard (proventricules ) of Cockroach and tube feet of Starfish

Answer 1

The correct option is B Nephridia in Earthworm, malpighian tubules in Cockroach and urinary tubules in Rat

Earthworms (annelids) have slightly more evolved excretory structures called nephridia. A pair of nephridia is present on each segment of the earthworm. Malpighian tubules are found lining the gut of some species of arthropods, such as the bee. They are usually found in pairs and the number of tubules varies with the species of insect.

So, the correct option is 'Option B'.
