Question

Reset Help Monophyletic Deuterostomes ("blue" taxa beginning with E, C, U, V) Paraphyletic Ecdysozoans ("orange"taxa beginning with N, A) Invertebrates (indicated by gray shading, all taxa except Choanoflagellates and Vertebrates) Lophotrochozoans ("yellow" taxa beginning with F, S, M) Protostomes (yellow" and "orange" taxa beginning with F, S, M, N, A)

Answer 1

1x Echinoderms, Cephalochordates, vrochordates and vertebrates - they have the development of anus firstly and then mouth is formed. so they are called Dueterostome 27 Nematodes and Arthropods have malting character because they have larva, papa and adult character in whole life cycle. So, there are ecdyson hormone is needed for this molting. They are called Ecdysozoa. 3 The invertebrate group is paraphyletic. group. Because this group is formed by one ancestor but not all of its decendants. 47 Lophotrochozoa is a clade of protostome animals within the spiralia. The taxon. was established as ö monophyletic group based on molecular taxonomy. 57 Flatworms, segmented worms, Mollusks, Nematodes, Arthropods are protostome because their mouth is developed before the development of anus.
