5 Matching questions

  1. Complex viruses
  2. 6 Major organism groups
  3. How is the nomenclature system used
  4. Resolution
  5. Lytic cycle of a virus
  1. a complicated structures; part may be helical and part may be polyhedral(Ebola and cholera)
  2. b 1.Protozoa: Uniceallular eukaryotic organisms
    2. Algae: unicellular plants that contain chlorophyll capabale of photosynthesis
    3.Fungus: filamentous plants that lack chlorophyll
    4.Bacteria: all living organisms with procaryotic cells
    5.Rickettsia: Cellular organisms between bacteria and viruses that need a host to grow.
    6. Viruses: Submicroscopic parasitic thing that consists of a nucleic acid surrounded by a protein coat.
  3. c *when spoken genus and species are used
    *1st letter of genus is capitalized and the first letter of the species is lower case.
    *Genus and species are usually italicized.
  4. d Ends with the lysis and death of the host cell.
    1.attachment- bacteriophage attaches to host wall
    2.Penetration- bacteriophage penetrates host and injects dna
    3.Maturation- viral components are assembled in virions.
    Release- host cell lyses and new virions are released.
  5. e The ability of the microscope objective to seperate fine details.
    (the higher the resolution, the finer the detail seen)

  5. *Systemic:deep in the body and affects the tissues and organs.route of infection is inhalation

    *Subcutaneous: beneath the skin, transmission by implantation of spores or mycelia in a skin opening

    *Cutaneous:affects epidermis,skin,and nails;transmitted via infected hair clippers or shower room floors.

    *Superficial:localized to the hair shafts and surfaced epidermal cells

    *Opportunistic: occur in hosts with compromised immune systems.
