What is the purpose of classification in biology?

• To create new species

• To help study and group living things based on characteristics and genetics

• To eliminate certain species

• To increase the population of a species

Which of the following is a characteristic used to classify organisms into domains?

• Color of the organism

• Prokaryotic vs. eukaryotic cell structure

• Size of the organism

• Speed of movement

Of the following classifications, the smallest or least inclusive is (a)  

• order

• genus

• species

• class

The correct order of classification from the BROADEST group to the most narrow is:

• Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain

• Domain, Kingdom, Phylum, Class, Family, Order, Genus, Species

• Kingdom, Family, Order, Phylum, Domain, Class, Genus, Species

• Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Which level of biological classification is the LEAST specific?

• Domain

• Kingdom

• Genus

• Family

What is a cladogram used for?

• To measure the size of organisms

• To show relationships among organisms

• To calculate the speed of evolution

• To identify the color of organisms

• A two-word naming system for identifying species

• A process to measure genetic variation

• A technique to study embryology
