1. Were any of the features used in more than one Phyla? If
so, give an example of an organism from each phyla that shares the feature.

2. List three features from Table 1 that describe a Monarch
butterfly (Danaus plexippus)? Using the features you listed, determine
what phyla it is classified in.**********************************************llali) · Invertebrates and Vertebrates·? ‘ ; ,… 😕 +”:f.jlExperiment 2: Creating a Phylum KeyIn this experiment you will take a closer look at the characteristics that describe the eight majorphyla.Table 1 Table 2Procedure1. Table 1 contains all of the main features of the eight major phyla discussed in theIntroduction. Organize and identify which characteristics belong to which phyla in the key. Thenumber of rows in the key repre- sents the number of characteristics that fall into each phylum.2.
