How much more does cytokine 2 gene expression change in severe COVID-19 patients than in mild COVID-19 patients? cytokine 2: What can the researchers conclude from these data? fold change that increased cytokine 2 expression levels are the likely cause of cytokine storm in severe COVID-19 patients that cytokine storm symptoms are likely caused by decreased expression of cytokine 1 in COVID-19 patients compared to non-COVID-19 patients that cytokine 2 expression is increased in severe COVID-19 patients but cytokine 1 expression is not significantly different between severe and mild COVID-19 patients that cytokine 1 is not a factor in the negative outcome of severe COVID-19 patients

- Read in eTextbook - Chapter 19 page 405 - Replicative Cycles of Animal Viruses especially see Figure 19.8 The replicative cycle of an enveloped RNA virus After reading you need to do 2 things - see A and B below. A) Post an original post answering the 2 questions. using at least 6-8 sentences per answer. question 1: what are 2 good potential targets in SARS-CoV2 virus to stop it from functioning ? (HINT: Think antibodies targeting important viral proteins) question 2: what is the Pfizer Vaccine composed of? what does it target in SARS-CoV2 virus? Can you connect it to any concept from Ch 17 in your course?. EVOLUTION CONNECTION The success of some viruses lies intheir ability to evolve rapidly within the host. Such viruses evadethe host’s defenses by mutating and producing many alteredprogeny viruses before the body can mount an attack. Thus, theviruses present late in infection differ from those that initiallyinfected the body. Discuss this as an example of evolution inmicrocosm. Which viral lineages tend to predominate?Chapter 13: Viruses, Viroids, and Prions16. Bacteriophage: Compare and contrast virulent vs.temperate bacteriophage. In your response please address the following:a. Draw (separately) the components of the lytic and lysogenic cycle and describe the type of virus (virulent or temperate) that goes through each cycle.b. Identify and describe and key steps in each cycle.c. Is the infection productive or latent? Explain. *Be sure to define any terms and be specific in your response.
- The lack of evidence-based data is one of the reasons for the apparent lack of a unified global strategy in handling the present COVID 19 pandemics. Hussain (2020), echoed a proposed pathophysiology of SARS-CoV2 binding to ACE2 with high affinity as a virus receptor to infect humans through spike glycoproteins on the surface of its membrane. Armed with this premise, create a concept map of SARS-CoV2 pneumonia. Start by describing the viral impact on the cells of the respiratory system. Justify GIT manifestations and why the hypertensive elderly patient is particularly considered at greater risk for mortality.QUESTION S Which of the following viruses is the most frightening as a cause of a global pandemic because it is impossible to predict when the next pandemic will occur or how severe it will be? ⒸH5N1 virus O Ebola virus O Influenza virus OHIV virusQuestion 10 What is the cause of Variant Creutzfeldt-Jakob disease? O Avirus causes VCJD. O A eukaryotic pathogen causes VCJD. O A viroid cause VCJD. O A Prion causes VCJD.

You just learned about the transmission rate hypothesis for the evolution of pathogen virulence and the power of natural selection. Which of the following statements may go through your mind? - For individuals infected with a more virulent viral strain, each cough is likely to contain more virus particles when compared to individuals who are infected with a less virulent strain. Therefore, uninfected individuals will have a higher chance of being infected when encountering the droplets from individuals infected with a more virulent strain. - However, individuals infected with a more virulent viral strain is likely to get sick sooner and show severer symptoms, thus will have less time being out and about when compared to individuals infected with a less virulent viral strain. - If there is no public health measures on social distancing to prevent congregation,…ny lI Spring 2021- Edgen G blood-borne diseases can be + A r12.core.learn.edgenuity.com/Player/ iology II Spring 2021 Blood-Borne Diseases Quiz Active TIME REMAINING 53:06 Blood-borne diseases can be transmitted when one patient receives blood from an infected patient.

- Antigenic shifts in influenza viruses are represented by dra-matic changes in the viral antigens. It is likely they arise fromrare events in which:(a) Two different influenza viruses infect a cell at the sametime(b) Two separate viruses undergo lysogenic conversion(c) Two viruses conjugate(d) Mutations accumulate(e) All of the aboveAnswer the two questions below by reading the article 1, What was discovered in this article and how is it interesting 2, How is this discovery in the article related to genetics Article The novel SARS-CoV-2 coronavirus that emerged in the city of Wuhan, China, last year and has since caused a large scale COVID-19 epidemic and spread to more than 70 other countries is the product of natural evolution, according to findings published today in the journal Nature Medicine. The analysis of public genome sequence data from SARS-CoV-2 and related viruses found no evidence that the virus was made in a laboratory or otherwise engineered. "By comparing the available genome sequence data for known coronavirus strains, we can firmly determine that SARS-CoV-2 originated through natural processes," said Kristian Andersen, PhD, an associate professor of immunology and microbiology at Scripps Research and corresponding author on the paper.
