Why are viruses considered non-living?
They are not cells. They do not use energy to grow or to respond to their surroundings.

After attaching to the host cell what does the virus do?
Insert its genetic material/DNA

If a virus becomes latent, where will its DNA be found?
The virus DNA can be found within the hosts DNA sequence
300
Name 2 of the 4 shapes of a virus.
What are cylinder, crystal, sphere, and bacteriophafe
300
Bacteria are _______________, which means that the genetic material in their cells is not contained in a nucleus.
prokaryotes

What is the cure for rhinovirus (common cold)?
There is no cure for the common cold! We can only treat its symptoms.

What is one example of bacteria helping our environment?
decomposing (returning chemicals to the soil), cleaning up after an oil spill

A _________________ is a virus that infects bacteria.
bacteriophage
400
What are the three common shapes of bacteria?
spherical(cocci), rod-like(bacilli), spiral(spirillum)
400
Disease spreads because bacteria multiply so quickly. Compare/contrast binary fission and conjugation.
Binary fission (asexual reproduction) -- one bacterium divides into two identical cells Conjugation (sexual reproduction) -- one bacterium shares genetic material with another through a threadlike tube
400
How can a virus useful in the medical field?
Gene Transfer or Gene therapies.
400
Once an active virus has made enough copies to burst the host cell, what happens?
All the viruses spread and find new cells to infect
500
All viruses have two basic parts: an outer coat made of __________ and an inner core made of _______________.
protein, genetic material
500
What are the two kingdoms of prokaryotes and what is one characteristic of each?
Archae(extreme environments) & bacteria( no nucleus)
500
What are 3 ways to avoid contracting a virus?
vaccination, avoid infected people, wash hands, mosquito repellent/nets, nutritious diet/exercise/rest
500
The archaebacteria that live in the thick mud at the bottom of lakes and swamps produce a gas called ____________, which is a major component in about 20% of the Earth's natural gas.
methane
500
Why is the latent form of a virus often more deadly than active forms?
The body doesn't know that it's there and can't produce antibodies, when it becomes active it has already infected thousands of cells
