• Panthera Tigris

• Panthera tigris

• panthera Tigris

• panthera tigris

Multiple Choice

8A Scientists around the world use a standardized taxonomic system. Why would scientists want to use a taxonomic system that is standardized?

• In order to avoid confusion with the identification of organisms

• Because Linnaeus established the system

• So that Latin names can be applied for a practical purpose

• In order to place organisms in different groups

Multiple Choice

The 8 levels of classification, most broad 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

Multiple Choice

The most specific of the classifications is?

• class 
• order 
• genus 
• species

Multiple Choice

The most general in the order of classification is?

• Kingdom 
• Phylum 
• Class 
• Order

Multiple Choice

• 3; Archaea, Bacteria, Eukarya
• 2; Bacteria, Eukarya
• 1; Eukarya
• 3; Bacteria, Eukarya, Protists

Multiple Choice

What kingdom's organisms often live in super harsh environments?

• archea
• animalia
• plantae
• protista

Multiple Choice

The 2 kingdoms that make up Prokaryotes are?

Multiple Choice

8B: The classification of four trees are shown in the table. Which two trees are the most closely related?

• Taiwan catkin yew and lodgepole pine

• Lodgepole pine and Japanese maple

• Japanese maple and Taiwan beech

Multiple Choice

8A: Organisms are classified today using the Linnaean system, and the following table shows the taxonomic classification of two marine organisms living along the Pacific Coast. Taxonomic classification is important to marine biologists because it provides a way to:

• prove that marine evolution occurs

• discover and name every marine organism on Earth

• designate Latin as the universal language of marine biology

• identify marine organisms and find evolutionary relationships between them

Multiple Choice

8B: A student used a microscope to study four members of the phylum Ciliophora. Members of this phylum move when propelled by hundreds of tiny cilia. Although these organisms belong to the same phylum, they are classified as different:

• families

• species

• kingdoms

• orders

Multiple Choice

8B Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful.

Based on this information, which statement correctly describes the relationship between the two populations of tree frogs?

• They are in the same species but different kingdoms.

• They are in the same class but different phyla

• They are in the same family but different orders

• They are in the same genus but different species.

Key Points

• Define taxonomy

• Scientific names (Genus and species)

• Why is classification important

• Levels of taxa (in order from most broad to more specific)

• Three domains of life characteristics
