|
Term
| Diff. b/t Bergey's Manual of Determinative Bacteria & Bergey's Manual of Systematic bacteria? |
|
Definition
Determinative Bacteria is information for identification of bacteria.
Systematic bacteria is more taxonomy based (classification) on DNA technology. |

| Taxonomic hierarchy for eukaryotes |
|
Definition
|
|
Term
| A prokaryotic species is defined as |
|
Definition
| A population of cells that share certain rRNA sequences; in conventional biochemical testing, it is a population of cells with similar characteristics. |
|
|
Term
Define Strain.
Recognize the notation for a strain |
|
Definition
Genetically different cells within a clone.
Strains are identified by numbers, letters, or names that follow the specific epithet. |
|
|
Term
| Why viruses not included in the classification system for living things. |
|
Definition
| Viruses are obligatory intracellular parasites o.i.p, and use host cells to multiply. Therefore, they are not classified in any of the 3 domains. |
|
|
Term
| Describe the structure of a virus |
|
Definition
-Acellular: not composed of cells.
-Nucleic Acid (DNA or RNA) + protein coat (capsid).
-Some covered by envelope. |

Definition
| An organism that is self feeding, using an inorganic chemical and C02 as its energy source. |
|
|
Term
|
Definition
| An organism that feeds on others (can't make it's own food), needs to acquire nutrients from the environment. |
|
|
Term
| Define facultative anaerobe |
|
Definition
Are organisms that can live in environments with oxygen, but continue to grow in environments with low oxygen.
Ex. Escheriche coli that are found in the human intestines. |
|
|
Term
|
Definition
An organism that requires a high salt concentration for growth or survival.
Ex. The dead sea. |
|
|
Term
| Define Hyperthermophiles (extreme thermophiles) |

Definition
Organism that require growth temperatures of at least 80 degrees Celsius.
Ex. Hot springs with volcanic activity. Sulfur is an important metabolic activity. |
|
