In Linnaeus’s binomial nomenclature system, which we still use today, the first part of an organism’s two-part scientific name is its:
Domain
Kingdom
Genus
Species
Why does the classification system keep changing?
New and improved knowledge about organisms helps us group them in new ways that make more sense.
New organisms are sometimes discovered that don’t fit into the old classification system.
New scientific tools, like more powerful microscopes, allow us to study organisms in new ways and learn more about them.
All of the above.

Fungi
Bacteria
Protista
Plantae
Which of the following statements is true of dichotomous keys?
They identify organisms by separating them into kingdoms.
