| 8 Linnaeus's naming system each organism is given a two-part name | Binomial nonmenclature |
| 9 why is Taxonomy useful to scientist | once an organism is classified scientist know a lot about that organism |
| 10 series of paired statements that describe the physical characteristics of different organisms | Dichotomous Key (Taxonomic key) |
| 11 first part of an organism's scientific name classification grouping that contains similar,closely related organisms | Genus |
| 12 a group of similar organisms that can mate and produce fertile offspring in nature name often describes a distinctive feature | species |
| 13 organisms that are classified in the genus ______ share features such as sharp,retractable claws and behaviors such as hunting | Felis |
| 14 together,a genus and a species name identify _________ | one kind of organism |
| 15 why is binomial nomenclature helpful to scientist | it makes it easy for scientists to communicate about an organism because everyone uses the same name for the same organism |
| 16 scientist understand that certain organisms are similar because they share a _____________ | common ancestor |
| 17 a _________ is the broadest level of organiztion | kingdom |
| 18 the most broadest level when using the 8 levels of classification | domain |
| 19 the second level when using the 8 levels classification | kingdom |
| 20 the third level when using the 8 levels of classification | phylum |
| 21 the forth level when using the 8 levels of classification | class |
| 22 the fifth level when using the 8 levels of classication | order |
| 23 the sixth level when using the 8 levels of classification | family |
| 24 the seventh level when using the 8 levels of classifcation | genus |
| 25 the eight level when using the 8 levels of classification | species |
| 26 organisms at lower levels _____________________________________. | share more characteristics with each other |
| 27 by working through the statements in the key in order,the person can eventually _______________. | identify the organism |
