Explain why Aristole is importantant.
He developed the 1st classification system; put all organisms into 2 groups (plants & animals)
How does Linneas' system categorize organisims?
Based on physical characteristics & structual characteristics
What language is used for naming organisms? Why is that language used?
Latin so that all scientist can identify organisms in one language no matter the language they speak.
List the taxonomic categories from largest to smallest.
Kingdom< Phylum< Class< Order< Family< Genus< Species
List the 6 kingdoms.
(Archeabacteria, Eubacteria)- used to be monera, Protist, Fungi, Plants, & Animals
Why aren't viruses alive?
They cant grow develop, carryout repiration, not made of cells + cant replicatew/out a host cell.
Define provirus (prophage).
Viral DNA is integrated into the host cell DNA & replicates each time the host cell replicates (lysogenic cycle)
List and discribe the steps of the lytic cycle.
5. Lysis Release
List and discribe the steps of the lysogenic cylce.
3. Pro-virus Formation
4. Cell Division
Viral replication that occurs when the virus uses reverse transcriptase to make DNA from RNA
What is peptidoglycan and how does it relate to the kindoms of prokaryotes?
Carbohydrate found in the cell walls of some bacteria. Eubacteria has it, Archeabacteria do not.
What are chemoautotrophs?
Organisms that must take in organic molecules for both energy & carbon
What are photoautotrophs?
Organisms that uses energy from sunlight to convert carbon diovide of H2O to carbon compounds
What is conjujation?
Form of sexual reproduction in which some prokaryotes exchange genetic information
Give 3 ways bacteria is important and useful.
Decomposers, nitrogen fixers & human uses food, cleaning oil spills a creating medicine
Prions are composed of infectious_____ but have no______ to carry genetic information. They cause other proteins to fold themselves incorrectly resulting in imporper functiong.
Particles -- RNA or DNA
Give 3 humans prion diseases.
(CJD) Creutzfield Jacob Disease, Gertsman - Straussler- Scheinker Syndrome (GSS) & Fatal Familar Insomnia (FFI)
