Linnaeus developed a naming system called binomial nomenclature. In binomial nomenclature, each organism is given a unique two-part scientific name that consists of the genus and the species to which it belongs.

B. multi-part name describing several traits

Through knowing the genetic material of organisms, it allows the scientific community to compare their striking similarities and differences. It can give an insight regarding the evolutionary relationship between organisms which appear differently but share a common ancestor.

C. Even dissimilar species can be compared at the level of certain genes.

Members of the kingdom Eubacteria and kingdom Archaebacteria consists of tiny prokaryotic cells that are only seen under a microscope.

C. I and II only

Evolutionary descent and gene similarity are relatively connected with each other. If two species have the same DNA sequence in their genes, this indicates that they are sharing a common ancestor.

A. Species A and B shared a relatively recent common ancestor.

A molecular clock model uses genetic material, particularly how the DNA undergoes mutation, to estimate how long an evolution takes place independently between two species.

C. molecular clock

Living things are classified under three domains. The three domains are Bacteria, Archaea, and Eukarya.

E. domain

Bacteria corresponds to two domains which are domain Bacteria and domain Archaea because members of these two domains are all prokaryotes and possess the characteristics of a bacterial cell. In domain Bacteria, it consists of the kingdom Eubacteria, whereas in domain Archaea, it consists of kingdom Archaebacteria. Since domain Eukarya consists of eukaryotes, it does not correspond to the characteristics of a bacteria.

D. two domains

According to the diagram:
1. Only roaches and mantids share a recent common ancestor.
2. Termites and mantids share an ancestor that is older than the ancestor of roaches and mantids.
3. Termites and roaches share an ancestor that is older than the ancestor of roaches and mantids.
4. All three insects share a common ancestor.

Therefore, all choices fit the information stated on the diagram.

E. I, II, and III
