When 2 organisms share many of the same classification levels what does that say about those 2 organisms?

Answer 22

The more classification levels that two organisms share, the more characteristics they have in common.

7. What phylum does the great horned owl belong to? Family? Scientific name?

Answer 23

Phylum- Chordata Family- Strigidae Scientific name- Bubo virginianus

Question 24

8. What is a field guide?

Answer 24

Field guides are books with illustrations that highlight differences between similar looking organisms.

Question 25

9. What is a taxonomic key?

Answer 25

Taxonomic keys are a series of paired statements that describe the physical characteristics of different organisms.

Question 26

Explain Darwin’s theory.

Answer 26

Two groups of a single species can accumulate enough differences over a long period of time to eventually become two separate species. This process is called evolution.

Question 27

11. What is the importance of a common ancestor when determining evolutionary history?

Answer 27

When an organism shares a common ancestor they share an evolutionary history.

Question 28

List 2 ways to determine evolutionary history.

Answer 28

Comparing structure and chemical make-up

Question 29

Why would scientists study the chemical makeup of an organism?

Answer 29

The more closely two species are related, the more similar the chemicals that make up their cells.

Question 30

What are the three domains into which organisms are classified?

Answer 30

Bacteria, Archaea, Eukarya

Question 31

2. How are organisms placed into domains and kingdoms? Hint, there are 3.

Answer 31

``` Cell type (prokaryote or eukaryote) Ability to make food (autotroph or heterotroph) Number of cells in their bodies (unicellular or multicellular) ```

Question 32

3. Members of the domain Bacteria are what?

Answer 32

Prokaryotes

Question 33

4. A prokaryote is what?

Answer 33

A prokaryote is an organism whose cell lacks a nucleus.

Question 34

A nucleus is what?

Answer 34

A nucleus is a dense area in a cell that contains nucleic acids.

Question 35

6. How is the nucleus of prokaryotes different from other organisms?

Answer 35

There is not a nucleus in a prokaryote. Or nucleic acids are not contained in the nucleus.

Question 36

Members of the domain Archaea can be found in what types of environments?

Answer 36
