Linnaeus came up with the way we scient ifically name animals:

The system for naming organisms called

In this system, all of the scient ific names are ___________________________________

Ex) all organisms in kingdom Animalia have ______________ (are able to move)

PHYLUMS

Inside each Kingdom there are different Phylums

Ex) all organisms in the phylum Chordata have a ___________

CLASS

Inside each Phylum there are different Classes

Ex) all organisms in the class Mammalia have ________

ORDER

Inside each Class there are different Orders

Ex) all organisms in the order Carnivora ________________

FAMILY

Inside each Order there are different Families

Ex) all organisms in the family Felidae are _______________________

GENUS

Inside each Family there are different Genuses

Ex) all organisms in the genus Felis are __________________

SPECIES

Inside each Genus there are different species

Ex) all organisms in the species domesticus are ___________________

BINOMIAL NOMENCLATURE

Each animal has a unique name known as the ______________________

The naming system used is called ____________________________

(bi=2 nomial=name, nomen=name clature=system)

The scientific name is made up of the _________ and the ___________

they are always written in italics or underlined

The Genus name is capitalized

The species name is lower case

e.g. scientific name of human :

UNIT TEST PRACTICE Directions: Answer each multiple choice question by circling the best answer and defend your answer

in the textbox that is below.

1. A species that lacks the variation necessary to adapt to a changing environment is more likely to

A. develop many mutated cells

B. become extinct over time

C. begin to reproduce sexually

D. develop resistance to diseases

2. If an ecosystem is changed through a natural disaster, organisms will have the best chance of

survival if

A. their environment has few abiotic factors

B. the organisms are large

C. the population size is small

D. their species exhibits genetic variation

3. In an environment that undergoes frequent change, species that reproduce sexually may have an

advantage over species that reproduce asexually because the sexually reproducing species

produce

A. more offspring in each generation

B. identical offspring

C. offspring with more variety

D. new species of offspring in each generation

4. Due to a mutation, a kangaroo living in a population in Australia is born with increased leg strength.

This trait allows the kangaroo to escape predators more easily than the other kangaroos in the

population. It is able to successfully pass on this adaptation and many more kangaroos with this

trait are born.

Explain how evolutionary change might occur in this populat ion of kangaroos over time. In your

answer be sure to include the concepts of

-Variation

- Natural Selection

5. A population of bats feeds on flying insects. Some of these bats have a gene that results in much

stronger flight muscles than those of the other bats in the area. Explain how this occurrence could

lead to evolutionary change within this species of bat. In your answer, be sure to include the

concepts of

- Variation

- Competition

- Natural Selection
