- 12. Multiple ChoiceWhat do viruses need to reproduce?they need genetic materialThey need a host cellThey need bacteriaThey need insulin
- 13. Multiple ChoiceDuring an infection, some viruses remain inside cell but do not cause symptoms of disease. The graphic below depicts the...lytic cycle and the host cell is destroyed by rapidly reproducing viral particleslytic cycle and the viral nucleic acid inserts into the host cell chromosomelysogenic cycle and the viral nucleic acid inserts into the host cell chromosomelysogenic cycle and the viral nucleic acid replicates independently of the host cell chromosome
- 14. Multiple Choice
The outer protein coat of a virus is called a –
DNA core
Capsid
Bacteriophage
Tail sheath
- 15. Multiple ChoiceAntibiotics kill virusesTrueFalse
- 16. Multiple ChoiceWhich viral life cycle allows viral genetic material to lay dormant while the host cell reproduces?lyticmitosislysogenicS phase
- 17. Multiple ChoiceWhich of the following is one important difference between a virus and a bacterial cell?a virus is much larger in size than a bacterial cella virus always causes more severe disease than a bacterial cella virus can never reproduce on its own, but a bacterial cell cana virus does not contain genetic material, but a bacterial cell does
- 18. Multiple Choicewhich of the following illnesses is caused by a virus?common colddiabetesstrep throatmalaria
- 19. Multiple Choice1) Which of the following is effective in reducing the number of viral infectionsantibioticsvaccinesinhalersnone of the above
- 20. Multiple ChoiceAccording to cell theory, why are viruses not considered living organisms?Viruses cannot reproduce outside a living organismViruses do not contain genetic materialViruses cannot cause diseases in other organisms.Viruses do not contain organic compounds
- 21. Multiple ChoiceThe projections on the surface of this virus allow the virus to —move inside a host cellattach to a host cellcontrol a host cell’s DNAsignal other viruses to infect a host cell
- 22. Multiple ChoiceEmma visited her family doctor in November to receive a flu vaccination, as it has been a very harsh flu season. As the doctor escorted Emma to the checkout station, he reminded her that it is very important that she return next year to receive another flu shot. Why must Emma get a new flu vaccination every year?Because her immunities will wear off.Because the doctor wants to make more money by selling more vaccines.Because the influenza virus mutates rapidly and this year’s vaccine will not be effective against next year’s flu.Because the vaccine builds up in a person’s system. The more vaccines Emma receives the higher her immunity to the virus.
- 23. Multiple ChoiceA capsid isa structure that directly causes cell lysisthe type of virus that attacks bacteriathe genetic material of a virusthe protein coat of a virus
- 24. Multiple ChoiceHow are MOST viruses spread?breathing in the same air as someone that is infected.bodily fluidsdabbing with infected folksplaying in the rain
- 25. Multiple ChoiceViruses can attack ?humansplantsbacteriaall of these
- 26. Multiple ChoiceWhich is smaller, a virus or a bacteria?virusbacteria
- 27. Multiple ChoiceWhich best describes the lysogenic cycle?A person who is infected with the herpes virus may develop a cold sore when the virus is in the lysogenic cycle.The lysogenic cycle occurs mainly in extremely infectious diseases that rapidly cause infection.In the lysogenic cycle, genetic material from the virus and host cells are integrated and are called a provirus.In the lysogenic cycle, virus particles are produced and assembled within the host cell.
- 28. Multiple ChoiceWhat is the 1st step of virus infection?EntryAttachmentReplicationAssembly
- 29. Multiple ChoiceThe ______________ is the cycle of viral infection, replication, and cell destruction.pathogenic cyclelytic cyclelysogenic cycleviral cycle
- 30. Multiple ChoiceWhen a virus injects its DNA and it merges with the host cell's DNA, which cycle is occurring?MitosisMeiosisLytic CycleLysogenic Cycle
