Is the possession of three tissue layers homologous or convergent among animals? Explain it.
Homework Answers
Three germ layers are called convergent extension..that is ectoderm,endoderm, mesoderm .All these three layers process in embryo reconstructed to converge(narrow) one axis to another by cellular movement..This convergent extension is there in animals,birds and fish at the molecular,celluar and tissue level..

1) Look at information and examples of animals in the 9 phyla of macroscopic (visible) animals: Porifera, Cnidaria, Mollusca, Nematoda, Annelida, Platyhelminthes, Echinodermata, Arthropoda, and Chordata. 2) Make a list of characteristics for each phylum that you might be able to use to tell them apart. These should be physical characteristics such as body symmetry, having a head (or not), having legs (or not), what kind of skeleton the animal has (or not), etc. 3) Using the list from step...

1A. A colleague calls from Asia with a discovery of a new species. She describes the adult species as being a bilateral, coelomate organism. Which phylum could this organism belong? Select all that apply. Question options: Porifera Ctenophora Cnidaria Platyhelminthes Nematoda Mollusca Annelida Arthropoda Chordata Echinodermata Question options:1B. A week later, you get an email with more of a description. She then describes the organism being aquatic, specifically marine, a complete digestive tract, a closed circulatory system. Which phylums could...
