Binomial Nomenclature
T/F: For many species, there are often regional differences in common names
True
In taxonomy, a group at any level of organization is referenced as a...
Taxon
What fraction of organisms have been identified?
A fraction of all species

Species
How does binomial nomenclature compare to early versions of naming organisms?
They are shorter names, 2 instead of say 7
The 2nd part of the name is unique to...
The species in it's genus
Often the second part of the name is...
Latinized description of a trait or latinized name

Mammalia
The most general and largest taxon is...
Kingdom
The traditional classification tended to only look at what to categorize them?
Similarities in appearance
In evolutionary classification, species within one genus should...
Be more similar to each other than to other species
What do all living organisms have in common?
They are made of DNA
What is true about dissimilar organisms such as a cow and yeast? (Are they even tax related?)
Relatedness is determined by common genes
Scientists have found that humans and yeasts have...
Similar genes to make the same protein
All organisms in the kingdoms plant, fungi, and animalia, have this in common
Eukaryotes
Which kingdom contains heterotrophs and cell walls that are made of chitin?
Fungi
What three kingdoms were a system used by scientists in the late 1800s?
Animals, Plants, and Protista
Which of the kingdoms used to be grouped with plants?
Fungi
Some scientists propose that the kingdom Protista should be broken up into several kingdoms. Why would they want this?
The kingdom of Protists is very diverse
What domain has Eubacteria in it?
Bacteria
What domain contains organisms that live in extreme environments like ocean volcanoes at the bottom of the ocean?
Archaea bacteria
What two domains have only unicellular organisms in them?
Archaea bacteria and eukaryote bacteria
Having three domains today means that there are fundamental differences between bacterial and archaeobacteria. Is this a true statement?
Yes

Kingdom
If you were given the species name of an organism, such as coli, what is the largest taxon you could also assign that organism?
Genus
What is the main difference between the domain archaeobacteria and the domain Eubacteria?
Presence of a cell wall
If you know that an organism has a cell wall and is multicellular, what kingdom does it belong to?
Plant and Fungi
Using the chart, can you tell which domain has the greatest number of organisms?
No
Using the chart, if an organism has a cell wall, chloroplast, is unicellular, and has a nucleus, what is the domain?
Eukaryote domain
Using the taxon chart, which organisms are most closely related to each other?

Which taxon chart category indicates mammal or not?
Class
What is the order of the taxons?
Kingdom, Phylum, Class, Order, Family, Genus, Species

No
