Answer 1

Step 1: Fill in the table. We know that all these organisms are made up of cells, so we can mark an "X" under the "cells" column for each organism. Worms do not have legs or wings, so we leave those columns blank. Spiders have legs but not six, they have eight, so we mark an "X" under the "legs" column and leave the "6 legs" and "wings" columns blank. Carpenter ants (black) and flies both have six legs and wings, so we mark an "X" under the "legs", "6 legs", and "wings" columns for both. The filled table should look like this:\begin{array}{|l|l|l|l|l|}\hline\ &\ cells\ &\ legs\ &\ 6\ legs\ &\ wings\ \\\hline\ Worm\ &\ X\ &\ &\ &\ \\\hline\ Spider\ &\ X\ &\ X\ &\ &\ \\\hline\ Carpenter\ Ant\ (black)\ &\ X\ &\ X\ &\ X\ &\ \\\hline\ Fly\ &\ X\ &\ X\ &\ X\ &\ X\ \\\hline\end{array}Step 2: Add each of these organisms to the cladogram. The cladogram should start with the organism with the least traits (worm), followed by the organism with the next least traits (spider), then the organism with the next least traits (ant), and finally the organism with the most traits (fly).Step 3: Add traits that make the organisms different from each other to the tree. The traits that differentiate these organisms are the presence of legs, the number of legs (6), and the presence of wings. Step 4: According to your tree, which two species are more closely related: worms and spiders or worms and ants?Worms and spiders are more closely related because they are next to each other on the cladogram.Step 5: According to your tree, what species are flies most closely related to?Flies are most closely related to ants because they are next to each other on the cladogram and share more traits in common.
