Howard is constructing a model of the tree of life. Which strategy would most likely ensure that all of Earth’s organisms are represented somewhere in the model?

• Draw three branches for the domains: Bacteria, Archaea, and Eukarya.

• Draw four branches for the kingdoms: Protists, Fungi, Plants, and Animals.

• Draw a long vertical line, and label dots on the line to represent examples of each kingdom.

• Draw an outline of a tree, and label the leaves with the names of known species.

• Birds and reptiles have adaptations for surviving in similar habitats.

• Birds and reptiles both rely on DNA, RNA, and the universal genetic code.

• Birds and reptiles share many behavioral traits, such as laying eggs in nests.

• Birds descended from the most recent common ancestor of reptiles.

• The species is classified with other protists into Clade Animalia.

• The species, like other protists, is not classified in any clade.
