Unit 5 Individual Project Name: Date: • • • In column 1, list the Phylum name for each animal in column one using the nine Phyla listed in your text. In column 2, list all of the dichotomous key steps chosen when using the key to arrive at the Classification for each animal. In column 3, using the Dichotomous Key provided, determine the Classification for each animal pictured, and write the Class names under the Classification Column on the table. There are 9 animals in nine different Phyla. Be sure to look at every page.

List all of the dichotomous key steps chosen when using the key to arrive at the class for each animal. • In column 3, the Classification Column, write the class name for each animal from the dichotomous key provided and your key steps. First download U5 Animal Table 2018 document. Next, download the Dichotomous Key document. 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. For help on how to use the dichotomous key, download and review the document called How to Use the Dichotomous Key. Submit your completed table.

Explanation & Answer

Hi again bro, I finished it all. Just some notes for you>- I added an extra column with the name of each picture. - In Column 2> I added the steps numbers as mentioned in the Dichotomous Key provided. As there is no enough space to describe it fully besides, I think that`s how exactly asked.Best of luck for you. If you need anything in the future, Just ask...
