Characteristics of Microoganisms
what are viruses made of?
nucleic acids and a protein coat
What are two reasons viruses are so difficult to fight?
1) they are so small
2) they change rapidly and often
What do viruses need to reproduce?
A host cell.
what is immunity?
the state or quality of being resistant to a particular infectious disease or pathogen.
Pathogens
A pathogen is a bacteriam, virus, or other microoganisms that can make you sick, causing diseases or disorders.
how are viruses different from living cells?
they cant generate ATP.
What two characteristics of living things do viruses have?
1) they contain protein
2) they contain genetic material
What is the shortest cycle for viral reproduction?
The Lytic cycle.
Types of immunity
Natural and acquired
Why are proteins in the virus important.
The proteins on the outside of the virus are important, because they allow the virus to attach to the correct host cell needed to reproduce more viruses.
are microorganisms multi-celled,single-celled, or both?
they can be both
how does the virus fit on the surface of the host cell?
lock and key
What occurs after DNA is released into the host cell?
It changes the cell's activities causing it to make more viruses using the cell's own machinery which leaves this cell to infect other cells.
What do Vaccinations help with?
They help prevent disease and jumpstrart the immune system by inserting a weak non active virus to help train the immune system to fight off bacteria or invaders in the body.
what 2 microorganisms are found almost everywhere?
bacteria and archea
a plasma membrane is in what microorganism
bacteria
How Can Viral Diseases Be Prevented and Treated?
Good hygiene, Vaccines, and Anti-viral drugs
What parts of the viruses are used to attach to the host cell and reproduce?
The envelope of the virus contains proteins that can be used to attach to the host cell and reproduce.
What kind of Systems does Immunity work with?
They work with the integumentary system & circulatory system to block and prevent invaders like viruses from harming the body.
define Classification
the theory and process of ordering the organisms into groups
why cant antibiotics treat a viral infection
theyre surrounded by a protective protein coat
Four basic shapes of viruses
1) Crystals
2) Spheres
3) Cylinders
4) Spacecraft
What are the steps of the Lysogenic Cycle?
1.Virus attaches to host cell. 2. Injects DNA into host cell 3. Viral DNA activates 4. Hot cell assembles new virus 5. Host bursts open 6. Viral DNA spreads to other cells.
how many category's of microorganisms are there?
seven
what microorganisms fixes nitrogen from the atmosphere?
