What kingdoms did Linnaeus originally use for his classification system?

• Fungi and Protista
• Fungi and Animalia
• Plantae and Protista
• Plantae and Animalia
  

Which of the following sequences represents the classification of an organism from most general to most specific?

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

According to the phylogenetic tree,, which two groups of organisms have the most genetic differences?

• rotifers and nematodes
  
• mollusks and annelids
  
• mollusks and arthropods
  
• echinoderms and jellyfish
  

Which two species are the most closely related?

• I and II
• II and V
• I and V
• V and VI
  

What is the best explanation for the continual changes in the classification system of organisms?

• All organisms struggle for existence and become extinct.
• All organisms compete to be at the top of the food chain.
  
• Technological advances have allowed scientists to better compare organisms.
  
• More species have been discovered, but scientists have not analyzed all the data
  

What is the difference between the full classification of organisms and their scientific names?

• The full classification of organisms and their scientific names vary in different countries
• The scientific names of organisms include the order and family of the organisms, but the full classification includes only the species name.
  
• The full classification of organisms will include more categories of organisms than their scientific names.
  
• The scientific names of organisms include a single nomenclature, but the full classification includes various nomenclatures.
  

Which two organisms in the chart below have chromosomes that are most similar in genetic composition?

• cow and chilean flamingo
• grizzly bear and blue whale
• clown fish and chilean flamingo
• horse and clown fish

The diagram shows the evolutionary relationships between several groups of organisms.  Organisms with the fewest biochemical similarities would most likely be found in which pair?

• 1 and 2
• 3 and 4
• 1 and 4
• all of the above

According to the dichotomous key, what is the scientific name of worm 2?

• Acanthocephala
• Ascaris
• Lumbricus
• Nais

What is the best way to determine the classification of an organism?

• Compare DNA sequences
• Examine what the organism eats
• Compare fur patterns
• Examine migration trends
