EOC Classification Review

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.

What taxa are used in order to give an organism a scientific name?

• genus and species

• kingdom and species

• kingdom and genus

• only the species

Some students conducted a laboratory investigation to learn more about the physical properties of different elements. They observed four samples and recorded their observations in the table below. Based on these observations, which sample is most likely a nonmetal?

• Sample 1

• Sample 2

• Sample 3

• Sample 4

A student is asked to identify an unknown substance. He observes that the element is brittle and solid. He also observes that the substance is not a good conductor of heat or electricity. At which location in this periodic table would the element most likely be found?

• 1

• 2

• 3

• 4

What is the primary reason for the periodic revision of the classification system in biology?

• To accommodate new species discoveries

• To reflect changes in scientific consensus

• To incorporate technological advancements

• To align with international standards

Which of the following is a key factor in determining the classification of an organism?

• Habitat

• Diet

• Genetic makeup

• Size

What is the significance of binomial nomenclature in scientific classification?

• It provides a unique name for each species

• It describes the habitat of the species

• It indicates the diet of the species

• It shows the size of the species
