Taxonomy Review

One of the smallest organisms in the animal kingdom is the tardigrade, also known as the "water bear." When a Biology student looks into his microscope he sees the four water bears from the image above. While all these water bears belong to the phylum Tardigrada, they are each classified as different:

• class

• genus

• species

• order

Most organisms are known by their common names, which vary by region and language. They also have scientific names based on their classification. How are scientific names determined?

• By using trinomial nomenclature, where the first part of an organism's name is its order, the second part is its kingdom, and the third part is its phylum.

• By using polynomial nomenclature, where the first part of an organism's name is its order, followed by its domain, species and kingdom.

• By using binomial nomenclature, where the first part of an organism's name is its genus, and the second part is its species.

• By using uninomial nomenclature, where the single name is a combination of the kingdom and order.

Which statement is true about the dendrogram in the image?

• The Antilocapridae is more closely related to the Moschidae than the Cetacea is to the Cervidae.

• The Suidae is more closely related to the Tragulidae than the Cervidae is to the Bovidae.

• The Bovidae is more closely related to the Tragulidae than the Cetacea is to the Hippopotamidae.

• The Giraffidae is more closely related to the Bovidae than the Moschidae is to the Cervidae.

Which kingdom has complex organ systems?

• Kingdom Protista

• Kingdom Animalia

• Kingdom Fungi

• Kingdom Archaea (Archaebacteria)

Which kingdom is not eukaryotic?

• Kingdom Protista

• Kingdom Animalia

• Organisms in Kingdom Plantae are all heterotrophic.

• Organisms in Kingdom Protista are prokaryotic.
