What is an example of a host to a virus?
you!
humans
animals
plants
An example of a host/parasite relationship is
A shark allowing small fish eat parasites in exchange for protection
A crocodile allowing small birds to eat from its mouth
Fleas sucking blood from a dog
What are the two basic parts of ALL viruses?
capsid
flagella
core of genetic material
cell wall
Select all the apply:
What does the capsid do?
protects the inner part of the virus
allows virus to invade a host
allows the virus to move
allows the virus to invade a parasite
True or False?

one parent cell
two parent cells
Conjugation is an example of __________________________
while binary fission is an example of _______________________________.
sexual reproduction, asexual reproduction
asexual reproduction, sexual reproduction
hidden viruses, active viruses
active viruses, hidden viruses
Does binary fission create more bacteria cells?
Yes
No
Sometimes
Does conjugation create more bacteria cells?
Yes
No
Sometimes
What happens during conjugation?
Bacteria cells double their genetic material and divide from one cell into two
Bacteria cells swap their genetic material to create a new version of themselves
Bacteria cells invade a host cell and immediately inject them with genetic material
Bacteria cells invade a host cell and allows the host cell to divide so bacteria's genetic material spreads
