Question
Chapter 17, Problem 1FFT
Summary Introduction
To describe: The morphological features that need to be changed to produce an unsegmented body cavity.
Introduction: Annelids are classified based on their characters, morphology, anatomy, and most importantly their phylogeny. Some examples are marine bristle worms, leeches, earthworms.
Summary Introduction
To describe: The evidence of the transition between segmented and unsegmented body coelom in annelids.
Introduction: Phylum Annelida is a large phylum consisting of more than 22000 species. The members of these phylum are invertebrates having triploblastic cleavage.

What structure differentiates Ectoprocts and Brachiopods from other Lophotrochozoa?
Select one:
1-Complete digestive tract with two openings.
2- Fluid-filled coelom.
3- Triploblastic.
4- Suspension feeding via lophophore.
5- Trochophore larval stage.
Please provide explanations in detail for the correct option as well as the incorrect options.
Aside from ecdysis, describe two (2) common characteristics shared by the different smaller phylum under Ecdysozoa: Kinorhyncha, Priapulida, Nematomorpha.
Define adaptation. How could you use a comparative approach to test whether mesoglea within a scyphozoan medusa was an adaptation for buoyancy? How could you use a different criterion to test whether the eyes of cubozoans were adaptive? Where would a comparative approach prove a better way to assess the adaptive values of a tegument in internal parasites: in tapeworms or nematodes? Why?
