Biology Question on Kingdom Animalia
Metameric segmentation is the characteristic of:
A
Platyhelminthes and Arthropoda
B
Echinodermata and Annelida
C
Annelida and Arthropoda
D
Mollusca and Chordata
Answer
Annelida and Arthropoda
Explanation
Solution
Both Annelida (e.g., earthworms) and Arthropoda (e.g., insects, crustaceans) exhibit metameric or segmented body plans, where the body is divided into distinct segments or repeating units along the length of the organism. This segmentation allows for greater flexibility and specialization of body parts.
So, the correct option is (C): Annelida and Arthropoda.
