The 8 levels of classification, broadest to most specific.

• Domain, Genus, Family, Order, Class, Phylum, Kingdom, Species
• Domain, Species, Kingdom, Genus, Phylum, Family, Class, Order
• Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
• Order, Kingdom, Species, Domain, Phylum, Family, Class, Genus

Four of the kingdoms include eukaryotes and the other two include

• plants

• fungi

• animals

• prokaryotes

The structural similarity shown in the organisms pictured here suggests that –

• similar bones are the same size in all animals.

• the organisms have common ancestors.

• some bones in the skeleton have immovable joints.

• only quadrupeds need the humerus bone.

The diagram shows light- and dark-colored beetles that live on a tree. Which result is most likely to occur to the beetle population due to predation over time?
