1mmUnicellularIf multicellular thay lack different tissues
◍ Koch.
Answer: Who developed a set of criteria that could be used to establish a
causative link between a particular microorganism and a particular disease?
◍ acellular microorganisms.
Answer: viruses -protein and nucleic acid, viroids - RNAsatellites -nucleic
acid with a protein shellprions- protein
◍ Jenner.

vaccination procedure against smallpox?
◍ Tyndall.
Answer: Whose work on spontaneous generation first demonstrated the
existence of a very heat-resistant form of bacteria that are called
endospores?
◍ Cellular microorganisms.
Answer: fungi - yeast moldsprotists - algae, Protozoa, slime moldsbacteria
-E Coliarchaea - methanogens (natural gas)extreme environments
◍ prokaryotic cell.
Answer: cell that does not have a nucleus or other membrane-bound
, organelles.
◍ Eukaryotic cells.
Answer: Contain a nucleus and other organelles that are bound by
membranes.
◍ Carl Woese.
Answer: Devised a system of classification based on the cellular
organization of organisms (bacteria and archaea)
◍ Protista Kingdom.
Answer: Single cell, microscopic organisms, EUkaryotic cells
◍ Evidence supporting RNA as primary role in evolution of life.
Answer: - Some RNA molecules are catalytic- RNA catalyzes peptide bond
formation during protein synthesis- ATP (energy currency of cell) is a
ribonucleotide- RNA can regulate gene expression
◍ Bacteria.
Answer: Can be pathogens (Black Plague)Human biomeBreak down dead
animal and plant cellsUsed to make bread cheese antibiotics vitamins and
enzymes
◍ Bacteria are abundant where.
Answer: Extreme sites of temperature PH and salinity. Major part of human
microbiome
◍ Domain Archaea.
Answer: One of the three domains of life; contains prokaryotic cells that
often live in extreme habitats and have unique genetic, biochemical, and
physiological characteristics; its members are sometimes referred to as
archaea.
◍ False.
Answer: True or False: Fungi is a protist
◍ Domain Eukarya.
Answer: Domain of all organisms whose cells have nuclei, including
, protists, plants, fungi, and animals
◍ Major types of protists.
Answer: algae, protozoa, slime molds, water molds
◍ Protein.
Answer: What does RNA convert information stored in DNA into?
◍ Woese.
Answer: Who began the ribosomal RNA studies that led to the division of
prokaryotic organisms into the Bacteria and the Archaea?
◍ Eukaryotes (Fungi).
Answer: A nonmotile organism composed of long threadlike structures
formed from nucleated cells that is not-photosynthetic and absorbs its
nutrients is likely classified among ________________.
◍ Fluorescence Microscope.
Answer: A microscope that exposes specimens to ultraviolet, violet or blue
light and forms an image with the light emitted as a different wavelength
◍ Safranin.
Answer: The counterstain in the gram-stain
◍ Purple; colorless.
Answer: After the decolorizer has been added, gram-positive organisms are
stained __________ and gram-negative organisms are stained __________.
◍ Decreases.
Answer: As the magnification of a series of objective lenses increases, the
working distance ____________.
◍ Algae are.
Answer: photosynthetic and produce oxygen, foundation of aquatic food
chains
◍ Mycolic Acids.
Answer: Acid-fast organisms such as Mycobacterium tuberculosis contain
lipids constructed from what in their cell walls?
