surface proteins
pseudopod
2
During what process do two protists exchange genetic material?
cell division
conjugation
mitosis
meosis
3
The instructions for making a new copies of a virus are
coded in either RNA or DNA
found only in bacteriophages
part of a virus's capsid
coded in proteins on the surface membranes
4
Unlike lytic viruses, lysogenic viruses do NOT
enter the lytic cycle
inject their genetic material into the host cell
lyse the host right away
infect the host cell
5
Which of the following is NOT a way in which humans rely on prokaryotes?
to digest petroleum from oil spills
to synthesize drugs
to produce foods such as yogurt
to obtain ammonia
6
What is the basic structure of a virus?
DNA or RNA surrounded by a protein coat
a capsid surrounded by a protein coat
a tiny cell surrounded by a cell wall
a bacteriophage surrounded by a membrane
7
How do viruses cause disease?
by releasing toxins
by changing normal proteins
by destroying cells
by inserting prophages into DNA
8
What organisms are eukaryotic, that are not part of plant, animal or fungi kingdom?

13
A lytic infection concludes with the
production of messenger RNA
production of a prophage
bursting of the host cell
insertion of viral DNA into the host cell's DNA
14
What are used to classify bacteria?
size & where they live
how they reproduce & if they have DNA
if they have cell walls & their nuclei
shape & how they obtain their energy
15
What fungal structure is this a picture of?
yeast
hyphae
mycelium
mushroom
16
During a lytic infection, the host cell
contains a prophage
