Which one of the following groups of structures/organs have similar function?

  1. A
    Typhlosole in earthworm, intestinal villi in rat and contractile vacuole in .
  2. B
    Nephridia in earthworm, Malpighian tubules in cockroach and urinary tubules in rat.
  3. C
    Antennae of cockroach, tympanum of frog and clitellum of earthworm.
  4. D
    Incisors of rat, gizzard (proventriculus) of cockroach and tube feet of starfish.

Solution & Step-by-step Explanation

Nephridia in earthworms, Malpighian tubules in cockroaches, and urinary tubules (nephrons) in rats are all primarily involved in the process of excretion and osmoregulation.Typhlosole and villi are for absorption, while contractile vacuoles are for osmoregulation.Antennae and tympanum are sensory, while the clitellum is reproductive.Incisors and gizzards are for grinding/cutting food, while tube feet are for locomotion and respiration.
