|
a prion
|
lacks RNA and DNa
|
|
|
the function of the capsule in some bacteria is
|
to protect the cell
|
|
|
this group of bacteria is poisoned by oxygen
|
obligate anaerobes
|
|
|
this type of organism lives off other living organisms usually causing harm
|
a saprobe, and a parasite
|
|
|
short strands of RNA with no protein coat
|
viroid
|
|
|
"mad cow" disease is caused by
|
prions
|
|
|
which of the following structures is found in a bacterial cell
|
ribosomes
|
|
|
antibiotics work against
|
bacteria
|
|
|
give 2 living properties of viruses
|
they contain DNA, and they contain protein
|
|
|
give 3 nonliving properties of viruses
|
they don't eat, grow, or reproduce on their own
|
|
|
How does the imune system destroy a virus?
|
antibodies blind it so it can't find it's host
|
|
|
How does the immune system destroy a bacteria?
|
antibiotics blind the bacteria then the white blood cells engulf and digest them
|
|
|
name 3 ways a virus attacks cells. the virus has already entered the cell
|
-it goes into the nucleas and reassembles the DNA, effectively hijacking the nucleas, and makes new cells with it.
-A virus enters the cell, goes to the nucleas, and ataches to the cell's DNA and "sits" there. if the cell divides viral DNA is duplicated along with the cell DNA. It may activate later. - The virus enters the cell and carries abnormal codes that trigger abnormal cell division (cancer, and warts) |
|
|
protein markers match between infected cell and disease agent
|
virus
|
|
|
produce toxins
|
bacteria
|
|
|
antibiotics do not work against these
|
virus
|
|
|
is a prokaryotic cell
|
bacteria
|
|
|
you build antibodies after exposure to this (or these) pathogens
|
both bacteria and viruses
|
|
|
3 benefits of bacteria
|
growth hormones, insulin, and antibiotics, used to make food products, and they are decomposers
|
|
|
Give 3 ways bacteria are transmitted in the population
|
air, contact, and bodily fluids.
|
|
|
how is conjugation beneficial to bacteria
|
it generates more genetic diversity
|
|
|
circular ring of DNa found in bacteria
|
plasmid
|
|
|
chemical produced by infected cells to prevent a virus form taking over the cell
|
interferon

|
|
protein coat of a virus
|

|
bacteria absorb DNA from another bacterium
|
conjugation
|
|
|
these anaerobes are poisoned by oxygen
|
obligate anaerobe
|
|
|
these bacteria can enter the body through the air, settle first in the lungs, and cause extreme weakness and caughing
|
Tuberculosis
|
|
|
Give 2 problems that can arise from using antibiotics
|
yeast infections, and super bacteria that are immune to antibiotics.
|
|
|
what is the purpose of bacteria producing toxins
|
to weaken the host
|
