1Viruses affect only humans.
- AVerdadero
- BFalso
2Viruses are the most common cause of acute infections in humans.
- AVerdadero
- BFalso
3In 1892, Dimitri Iwanowski did a study with diseased tobacco plants that was very important for virology. This study showed that:
- ADiseases could be transmitted from one plant to another by an infectious agent smaller than bacteria.
- BPlants can also be hosts to viruses.
- CViruses within a plant host can survive deeply sub-zero temperatures.
- DViruses are living, much like their plant hosts.
4Viruses are cellular organisms.
- AVerdadero
- BFalso
5Viruses could be considered "Darwinian Machines" because:
- AThey were discovered by Charles Darwin.
- BThey operate only on 'survival of the fittest' principles.
- CDarwin invented viruses.
- DThey focus mostly on their kill potential.
6There is evidence suggesting that polio has been around as far back as:
- A2000.
- B1790.
- C0820.
- D3700 BC.
7Viruses are naturally set to evolve best when they maximize:
- ASpreading potential.
- BLethality.
- CSevere symptoms.
8Severe viral diseases are a failure of the virus to adapt to its host.
- AVerdadero
- BFalso
9A virus has two phases. In the first stage, [blank_start]the virus is on its own, as a virion[blank_end]. In the second phase, [blank_start]the virus has entered an infected cell[blank_end].
- Athe virus is on its own, as a virion
- Bthe virus is in its original host cell
- Cthe virus eats a hole in your skin
- Dthe virus has entered an infected cell
- Ethe virus is mutated
- Fthe virus kills the host
10All cellular life has the following characteristics in common (Check ALL that apply):
- ADNA and RNA (genetic material).
- BMakes proteins.
- CConverts chemicals to energy.
- DReproduction by division.
- EA cell membrane for regulation.
- FA host for compounds.
- GNo more than 50 nano meters in size.
- HHas a virion.
11There are two main types of replication cycles for viruses. [blank_start]In both cycles[blank_end], the viral genome enters the host cell. [blank_start]In the Lytic Growth Cycle cycle[blank_end], the viral genome is replicated, viral proteins are created, and the viruses assemble inside the cell then exit. [blank_start]In the Lysogenic cycle[blank_end], the genome is integrated into the host DNA and transmitted to the host's daughter cells.
- AIn both cycles
- BIn neither cycle
- CIn the Lytic Growth Cycle cycle
- DIn the Circle Cycle
- EIn the Lysogenic cycle
- FIn the Cell Cycle
12When washing your hands, you are more likely to destroy:
- AAn enveloped virus.
- BA non-enveloped virus.
- CYour knuckles.
- DProteins.
13Zoonotic viruses are primarily hosted by:
- AAnimals.
- BHumans.
- CFresh fruit.
- DZebras.
14Which of the following is NOT a factor affecting host range?
- ACell surface receptors and viral attachments and proteins.
- BAvailability of replication machinery.
- CAvailability to leave the cell and spread.
- DHost anti-viral responses.
- ELethality.
15Rabies can be an extremely slow virus, taking up to over a year to kill its host. This is because the virus:
- AIs sluggish.
- BTargets neurons, which have long axons slowing the process.
- CTravels through the blood stream, but slowly.
- DIsn't very dangerous, and takes multiple bites to really be dangerous.
16Bats and raccoons should not be handled with direct contact because:
- AThey might host rabies.
- BThey're furry.
- CThey can cause pertussis.
- DThey're endangered.
17Which of the following is NOT something we need to know to control a viral disease?
- AReservoirs.
- BModes of transmission.
- CMethods of inactivation.
- DLikelihood of back-mutation.
18Herpes viruses can be considered like the diamonds in the movie "Diamonds are Forever" because:
- AHerpes viruses remain in your system - they will be with you forever.
- BJames Bond has contributed heavily to the study of herpes viruses.
- CLike the diamonds in the movie, herpes are traded rapidly from person to person.
- DHerpes are extremely valuable.
19Cytomegalovirus is a common form of herpes that commonly has no side effects. In this group of people, however, cytomegalovirus can cause blindness.
- AChildren.
- BAIDS patients.
- CElderly.
- DPeople with rabies.
20Which of the following are true of Epstein Barr Virus, or infectious mononucleosis? (Check ALL that apply)
- A~90% of people have been infected by this.
- BIt is also called 'The Kissing Disease'.
- C~1% of the population has this virus.
- DIt is almost always lethal.
- EIt's an airborne virus.
21Some herpes viruses have oncogenic (tumor-causing) properties.
- AVerdadero
- BFalso
22Which of the following is NOT a potentially oncogenic virus?
- AHuman Papiloma Virus.
- BEpstein-Barr Virus.
- CHerpes virus type 8.
- DHepatitis B and C.
- EHepatitis A.

Kaposi's sarcoma - [blank_start]Blood vessels.[blank_end]- AThe lymphatic system.
- BHands.
- CHead and neck.
- DThe cervix.
- EBlood vessels.
24Lysis is a process in which non-enveloped viruses exit their host cell once they've multiplied enough. They do this by:
- ABreaking open the cell, killing it and exiting.
- BHollowing out the inside of the host cell to kill it and infecting other cells from the inside.
- CExiting from a small hole in the cell that doesn't harm it.
