Expert Solution & Answer
Answer to Problem 2STP
Correct answer :
Option (D).
Explanation of Solution
Explanation/justification for the correct answer :
Option (D) Rotifera. The given diagram represents an animal with three region, head trunk and foot. It also has a group of cilia like structure that help in feeding and locomotion. Hence, the correct answer is option (D).
Explanation for incorrect answer :
Option (A) Annelida. The Annelida is a group of segmented worms. As the given animal does not represent the features of worm, it does not belong to Annelida. Hence, it is an incorrect answer.
Option (B) Nematoda. The Nematoda includes the round worms having a cylindrical body, as the animal in the picture does not have a cylindrical body, it is not a Nematoda. Hence, it is an incorrect answer.
Option (C) Platyhelminthes. The Platyhelminthes are flat worms and have small head with no cilia. Hence, it is an incorrect answer.
