- The genome of which of the following types of animal virus can act directly as MRNA and be utilized by ribosomes without prior processing? O 1) retroviruses O 2) SSDNA viruses 3) -SSRNA viruses O 4) +SSRNA viruses 5) dsDNA virusesWhich of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions? "This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too." Group of answer choices a. Measles b. Parvovirus c. Coxsackie virus A d. RhinovirusWhy do scientists worry more about new strains of viruses like influenza and coronviruses as potential causes of deadly human pandemics, but they never talk about the next big Herpesvirus strain deadly pandemic? Which of the statements below helps partially answer that? We already have effective vaccines for Herpes. Influenza and CoV have more genes, more complex gene expression, and can undergo genetic recombination or reassortment, while Herpesviruses are more limited. Only humans get Herpesviruses, while animals can get Influenza viruses and Coronaviruses. dsDNA viruses aren't very transmissible and even when they are, they're not deadly. Influenza and CoV are RNA viruses which results in having higher mutation rates -- they can more easily jump between host species. Herpesviruses are dsDNA viruses and usually very host specific.

O 4) Host cell death 5) All of the aboveWhat would happen to a virus that found its way to an environment filled only with cells that were outside of its host range? a) This virus would evolve until it was able to use the surrounding cells as hosts b) This virus would actively transport itself to another area in search of host cells C) This virus would replicate until it found cells that were within its host range d) Nothing; this virus would not be replicated
- Suppose that a time machine allows you to go back in time (and to travel to Australia), and you have collected rabbits and Myxoma from the years 1955 and 1980. Once you are back in the twenty-first century, you infect both sets of rabbits with both sets of Myxoma viruses. The most likely result will be (1) that the rabbits from 1955 injected with the 1955 virus will have a survival rate than those same rabbits injected with the 1980 virus; and (2) that the rabbits from 1955 injected with the 1980 virus will have a survival rate than rabbits from 1980 injected with the 1980 virus.. A. lower; lower B. lower; higher C. higher; lower O D. higher; higher E. the survival rates will be the same in experiments (1) and (2)Describe the lysogenic cycle of a virus. What is the difference between the lytic and lysogenic cycle of a virus? What are vaccines? Define the words “Emerging Virus” and “Pandemic”. Give examples of human diseases caused by viruses. What is a prion and viron? Are prion and virons viruses? Give examples of human or animal diseases caused by prions and what organisms are affected. Book: Biology (Campbell) 11 edition Urry. Cain. Wasserman. Minorsky. ReeceAs a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate? Briefly explain why.
- Viruses are considered non-living microbes, and yet they are responsible for many major disease outbreaks in humans, animals, and even plants. Consider the following: How are these non-living microbes able to reproduce without metabolic functions? Can viruses be exploited to help humans fight bacterial pathogens? Which viruses are able to stay dormant in the human body and reactivate later in life or when immune defenses are compromised? What impact might travel outside of the United States have in blood, tissue, or organ donation?
