3. Every living organism has what classification groups as its unique name? __genus__ and __species__
4. The first letter of every genus name is ___capitalized (italicized)__.
5. The first letter of every species name is ___lower case (italicized)__.
6. What is binomial nomenclature? __2-part system for assigning a scientific name for every organism as it exists in the
Linnaean classification system___
7. Give one example of how you classification is used at school.
Classes (science, math, English, fine arts, tech), Graduation class (freshmen, sophomores, juniors, seniors), etc.

20. The image does not show orders of insects. Suggest three categories of insects that would likely be grouped into
orders. Hint: think about what kind of insects there are. Add your three categories to the image.
21. Create an addition to the image given the following information.
 Mollusks are divided into three classes: Class Cephalopoda (squids), Class Gastropoda (snails), Class Bivalve
(clams and oysters)
 Cephalapods have a few orders, one of which is Octopoda (octopus) and and another is Teuthida (squids)
 The scientific name for the common octopus is Octopus vulgaris.
 The scientific name for the common european squid is Loligo vulgaris.
