A scientist discovers a new bacterial species. Which activity would be the best way to determine the domain of the organism?

• calculate its lifespan

• observe its habitat

• examine its DNA

• monitor its diet

Which of the following is the correct order of the categories in the modern system of classification?

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

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

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

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

Some organisms have different common names in different parts of the world, but all organisms are given only one scientific name using binomial nomenclature. Which statement describes how the scientific name of an organism is written?

• It is written in English.

• It is written as genus and species.

• It is written as kingdom and phylum.

• It is written with quotation marks around it.

The image below shows an organism, Dionaea muscipula. This unusual organism can trap insects with its leaves as a food source, but gets most of its energy through photosynthesis. Which of the following is the correct classification for Dionaea muscipula?

• Plantae, because it is primarily autotrophic.

• Fungi, because it has multiple food sources.

• Archaea, because one of its characteristics is 'unusual.'

• Protista, because it uses tiny hairs as a trapping device.

Which of the following best describes why scientists identify organisms using binomial nomenclature in Latin or Greek instead of using common names?

• Scientists can communicate effectively to avoid confusion of common names.

• Scientific names in Latin sound more professional than the common names of organisms.

• Scientists have not had the desire to change the original system that was developed by Linnaeus.

• Scientific names allow newly discovered organisms to be named after the scientist who discovered them.

The table below provides information about four organisms. All four organisms are classified as Kingdom Animalia, Phylum Chordata, Class Mammalia. Which of these organisms are most likely classified in the same Order?

• Eastern mole, coyote, and red fox, because they all have thick fur.

• Coyote, eastern mole, and red fox, because they live in similar habitats.

• Eastern mole and side-striped jackal, because they have specified dietary needs.

• Side-striped jackal, red fox, and coyote, because they have shared physical characteristics.

In 1753, Carolus Linnaeus published a very important work titled 'Species Planetarium.' This work created a system that described and classified all the plant species known to exist at the time using binomial nomenclature. Which of the following best describes the importance of Linnaeus' contribution to classification?

• Linnaeus used new skills to name organisms.

• The 'Species Planetarium' is the sole published work about living things.

• The age of this system is the reason for scientific names in Latin and Greek.

• This system of classification was so well-designed that it is the basis of modern taxonomy.

Scientists classify organisms in a branch of science called taxonomy. Which scientific tool listed below would aid scientists in determining how closely related two organisms are so that the scientists could classify them?

• a meter stick to measure the sizes of the organisms

• an x-ray to examine the skeletal structure of the organisms

• a triple-beam balance to calculate the relative masses of the organisms

• an analog GPS tracker to investigate the habitats and ecosystems of the organisms

Scientists classify organisms into three domains and six kingdoms. In which kingdom are yeasts classified and why?

• Plantae, because they are eukaryotic.

• Protista, because they are prokaryotic.

• Fungi, because they are heterotrophic.

• Animalia, because they are autotrophic.

• body shape similarities

• presence or absence of photosynthesis

• presence or absence of a cell membrane
