Slide 1 Viruses and Other Acellular Infectious Agents Chapter 5 Slide 2 Slide 3 Slide 4 Slide 5 Slide 6 Viruses • Major cause of disease • Also important as a new source of therapy • New viruses are always emerging • Important members of aquatic world • Important in evolution • Transfer genes between bacteria Slide 7 Viruses • Acellular infectious agents • Only reproduce within living cells • Possess only one type of nucleic acid • DNA or RNA • Virologists • Scientists that study viruses • Virology • Study of viruses Slide 8 General properties of viruses • Virion • Complete virus particle • Consists of ≥ 1 molecule of DNA or RNA enclosed in a coat of protein • May have additional layers • Carbohydrates, lipids, additional proteins • Cannot reproduce independent of living cells nor carry out cell division as prokaryotes and eukaryotes do Slide 9 Generalized Structure of Viruses Slide 10 Virions Infect All Cell Types • Bacterial viruses are called bacteriophages (phages) • Most are eukaryotic viruses • Plants, animals, protists, and fungi • Classified into families based on • Genome structure, life cycle, morphology, genetic relatedness Slide 11 3 ways that viruses differ from living cells 1. Have a simple, acellular organization 2. The presence of DNA or RNA, but not both, in almost all virions 3. The inability to reproduce independent of cells and carry out cell division • In contrast t ...

Environmental justice.Not less than 300 words

Envrionmental JusticeThis week you have been exploring risk assessment and risk management, and what governments can do to prevent potential environmental health issues. Questions arise, however, on the equity of environmental justice. Is it fairly being provided in all situations without any group or community facing an undue amount of risk?Select a real environmental justice issue that is relevant to your geographic area, if possible, or that is of interest to you. Find a case in which a particular ethnic or SES group has or is bearing an undue share of risk from the location of a noxious site, including an industrial facility, mining waste site, nuclear plant, municipal landfill, Superfund site, incinerator, feedlot, abandoned toxic waste site, or polluted waterway. After researching,please respond to the following Describe the environmental justice situation, including when it occurred or if it is current. Discuss who is/was facing unequal risk or exposure, including the cultural or SES correlations. Describe what they are/were exposed to, providing supporting information on the level of risk and using scholarly sources such as ATSDR and journal articles as necessary. Explain the risk-management goal, and provide suggestions/examples for communicating the risk and engaging the stakeholders.Support your discussion by citing at least one primary research article.Do you assignment in APA format with at least two references. Make it 300 words
