Unit Four Classification Post-Assessment

Jaylen wants to create a dichotomous key to determine the relationship between tigers and bears. Which best describes how Jaylen should start his dichotomous key?

• He should start by determining the age of the tiger and bear.

• He should start by finding a shared characteristic between the tiger and bear.

• He should start by determining the function of the claws of the tiger and bear.

• He should start by finding a characteristic that separates the tiger from the bear.

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

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

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.

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

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

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

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

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

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

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

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

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

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

The table shows characteristics of a specific kingdom.

Characteristics

-mostly multi-celled, some are single-celled

-eukaryotic organisms

-can be heterotrophs or autotrophs

Which is most likely the kingdom described in the list?

• kingdom Plantae

• kingdom Animalia

• kingdom Protista

• kingdom Fungi

The pictures below show three organisms that Yolanda found outside. Based on the Linnaean system of classification, how would these organisms be organized?

• They would be classified differently, because they each start with different letters.

• They would be classified together, because they all have cells of the same size.

• They would be classified differently, because they belong to different kingdoms.

• They would be classified together, because they were all found in the same area.

Daniel is learning about how animals are classified into kingdoms and phyla. He is surprised to learn that living things were classified into two kingdoms, Animalia and Plantae, until the early 1900s. Where did scientists obtain the knowledge that they used to establish additional kingdoms?

• experiments conducted after the invention of the microscope

• a wide variety of genetic and field investigations around the world

• research conducted only in outer space

• research conducted mainly on genetic inheritance and clones

Seth and Ethan were assigned to create posters for their science class. Seth was told to create a poster showing the characteristics of the kingdom Animalia, and Ethan was told to create a poster showing the characteristics of the kingdom Fungi. The posters are shown at the left. Which student has a poster that displays an incorrect characteristic?

• Seth because not all animals are multi-celled

• Ethan because fungi cells do not contain chloroplasts

• Seth because not all animals are heterotrophic

• Ethan because fungi cells do not contain membrane-bound organelles
