Taxonomic Classification

Which factor best explains by classification systems change over time?

• changing environments lead to reclassification

• increased plant species lead to reclassification

• changes in food resources leads to reclassification

• increased knowledge of genetics leads to reclassification

A scientist finds a seashell. She wants to classify the shell. What two different characteristics would she examine to classify the seashell?

• blood characteristics and naming characteristics

• chemical characteristics and DNA characteristics

• physical characteristics and environmental characteristics

• physical characteristics and chemical characteristics

Which of the following identifies the levels of classification in the correct order?

• domain, kingdom, phylum, class, order, family, genus, species

• genus, species, domain, kingdom, phylum, class, order, family

• domain, kingdom, genus, species, phylum, class, order, family

• genus, species, phylum, class, order, family, domain, kingdom

A branching diagram uses shared characteristics to classify organisms. On a branching diagram that compares the major kingdoms of the Domain Eukarya, what label might appear to differentiate animals form organisms in the other kingdoms?

• membrane-bound organelles

• able to tolerate extreme conditions

Felicia's teacher gives her the following list of types of organisms. 1. Fern 2. yeast 3. Algae 4. insects Felicia needs to identify the kingdom for each type of organism. In what order could she list the kingdoms for organisms 1 through 4?

• Plantae, Fungi, Protista, Animalia

During a research project, a scientist collects snails from a beach. He finds several snails that have shells of about the same size and shape. However, the shells have very different patterns and colors. How could the scientist best decide whether the snails belong to different species or to the same species?

• He could study how the snails develop

• He could examine the snails' RNA and DNA

• He could classify the snails according to shell color.

• He could look for other physical similarities in the snails.

As Carolus Linnaeus was growing up, he was interested in botany and in the names of plants. His ideas have influenced generations of biologists. How did Carolus Linnaeus contribute to modern classification systems?

• He identified the three domains of life.

• He developed two-part scientific names.

• He standardized common names of organisms.

• He used chemical characteristics to classify organisms.
