Q: What distinguishing characteristic of annelid anatomy shows specialization and adaptation?


Read this paragraph and choose the correct option from the provided answers:

Annelids are divided into many repeating segments. The earthworm in Figure below is an annelid. You can clearly see its many segments. Segmentation of annelids is highly adaptive. Each segment has its own nerve and muscle tissues. This allows the animal to move very efficiently. Some segments can also be specialized to carry out particular functions. They may have special structures on them. For example, they might have tentacles for sensing or feeding, “paddles” for swimming, or suckers for clinging to surfaces.

 Choices:

- asymmetry

- beautiful

- compression

- segmentation


A:
segmentation
