Classification

At which classification level could two organisms belonging to the same group have the least in common?

• Species

• Family

• Genus

• Kingdom

Karren wants to create a dichotomous key to determine the relationship between cats and dogs. Which best describes how Karren should start his dichotomous key?

• He should start by determining the age of the cat and dog.

• He should start by finding a shared characteristic between the cat and dog.

• He should start by determining the function of the claws of the cat and dog.

• He should start by finding a characteristic that separates the cat from the dog.

What best describes a situation in which a dichotomous key would NOT be helpful?

• determining the similarities between a dog and a wolf

• determining the function of gills in a shark and a goldfish

• determining the common characteristics of a bat and a bird

• determining the relationship between a panda bear and polar bear

The chart below shows the taxonomic classifications of three organisms. Which two organisms are most closely related to each other?

• Humans and gorillas are most closely related because they belong to the same order.

• Squirrels and humans are most closely related because they belong to the same classes.

• Gorillas and squirrels are most closely related because they belong to the same phylum.

• Humans and gorillas are most closely related because they belong tp the same kingdoms

What is the best way to organize the several million different types of organisms on Earth?

• in chronological order by their date of discovery

• in numerical order by the age of the organism

• in groups based on their geological location

• in groups based on similar characteristics

• an animal with scaly skin and a shell but no external gills

• an animal with scaly skin and legs but no shell

• an animal with legs and coastal grooves but no tail

• an animal with external gills and a tail but no coastal grooves

Kelly is developing a dichotomous key to identify organisms. Which method is the best way for Kyle to begin developing his key?

• Kelly should identify a feature common to all of the organisms and discover that feature's function.

• Kelly should identify a list of characteristics from very broad to very specific that can be used to classify the organisms based on traits.

• Kelly should identify the organisms by placing them in groups based on where they are found.

• Kelly should identify the physical differences between all of the organisms that can be used to classify the groups based on their behaviors.

What is the hierarchical system used to classify organisms?

• It is a system where the groups of organisms at the top are the common ancestors of the groups of organisms at the bottom.

• It is a system where the groups at the top have the largest populations and the groups at the bottom have the smallest populations.

• It is a system where the largest groups at the top share only a few characteristics and the smallest groups at the bottom share the most characteristics.

• It is a system where the largest groups at the top are identified in the most locations worldwide and the smallest groups at the bottom are confined to small areas.

Which characteristic distinguishes organisms in kingdom Archaebacteria from organisms in kingdom Eubacteria?

• Organisms in kingdom Archaebacteria have circular DNA, and organisms in kingdom Eubacteria have linear DNA.

• Organisms in kingdom Archaebacteria are rod shaped, and organisms in kingdom Eubacteria are only cocci or spiral shaped.

• Most organisms in kingdom Archaebacteria are single-celled, while only some organisms in kingdom Eubacteria are single-cell.

• Most organisms in kingdom Archaebacteria live in extreme environments, while most organisms in kingdom Eubacteria live in moderate environments.
