Question;Question details;Organisms are placed in taxonomic classifications based on differences;and similarities of their traits. If you know what critical traits to;look for, it is possible to separate any animal into a taxonomic;category using a dichotomous key.;The common taxonomic categories are Domain, Kingdom, Phylum, Class;Order, Family, Genus, and Species (Specific Epithet). We are looking at;the Phylum and Class categories in this assignment.;Assignment details;Part 1: The assignment document contains a table with nine images. The;images are examples of nine different Animal phyla: Porifera, Cnidaria;Nematoda, Anthropoda, Platyhelminthes, Annelida, Mollusca;Echinodermata, and Chordata.;Download U5IP_Table.;Next, download Dichotomous Key;Use the Dichotomous Key to determine the Class category as shown for;each animal (picture), and;write the Class names under the Classification Column on the table.;List in column 2, all of the dichotomous key steps you chose when using;the key to arrive at the classification for each animal.;You will also need to list the Phylum name for each animal picture in;column one using the nine Phyla listed above. Once you have identified;the Class category for each animal using the Key, look up the correct;Phylum category using a credible reference.;Part 2: Answer the following questions as they relate to the nine phyla;in the assignment table.;Which phyla lack organs? What type of symmetry do they have?;List all of the phyla that show cephalization.;Do all organisms on the table have 3 germ layers (endoderm;ectoderm, and mesoderm)? If not, which phyla have fewer than three germ;layers?;One phylum on the table has more species than all the others. State;the name of this phylum, and provide several different examples of;species found in this phylum.;Fish do not all have the same skeletal structure. Describe the;differences among fish from the most primitive to more advanced types of;fish.;Describe the three types of mammals based on how their young;develop.
