100% Complete Solutions
Classification of organisms - ✔✔ Kingdom, Phylum, Class, Order, Family,
Genus, Species
Phylogenetic trees - ✔✔ a branching diagram that represents a hypothesis about
the evolutionary history of a group of organisms
Types of microbes - ✔✔ bacteria, archeae, fungi, molds, yeasts, protozoa, algae,
viruses, multicellular animal parasites
rRNA - ✔✔ The RNA component of the ribosome, and is essential for protein
synthesis in all living organisms.
Theory of RNA as the original hereditary material. - ✔✔ original molecule must
have fulfilled protein and hereditary function. Earliest cells may have been RNA
surrounded by liposomes.
Endosymbiosis - ✔✔ A process in which a unicellular organism (the "host")
engulfs another cell, which lives within the host cell and ultimately becomes an
organelle in the host cell; also refers to the hypothesis that mitochondria and
plastids were formerly small prokaryotes that began living within larger cells.
Horizontal gene transfer - ✔✔ A process in which an organism incorporates
genetic material from another organism without being the offspring of that
organism.
, Spontaneous generation - ✔✔ A hypothetical organic phenomenon by which
living organisms are created from nonliving matter.
Van Leeuwenhoek - ✔✔ First person to observe and describe microorganisms
accurately.
John Needham - ✔✔ Heated broth in sealed flasks.When the broth became
cloudy with microrganisms, he mistakenly concluded that they developed
spontaneously from the broth.
Lazzaro Spallanzani - ✔✔ Boiled open and closed flasks of broth to disprove
spontaneous generation.
Louis Pasteur - ✔✔ A French chemist, this man discovered that heat could kill
bacteria that otherwise spoiled liquids including milk, wine, and beer.
Joseph Lister - ✔✔ A surgeon who used carbolic acid to control wound infection.
Edward Jenner - ✔✔ Used a vaccination procedure to protect individuals from
smallpox.
Koch's Postulate - ✔✔ 1) Pathogen must be present in all disease cases 2) Isolate
pathogen, cultivate in pure culture 3) Inoculate into susceptible animal, initiate
disease symptoms 4) Re-isolate pathogen, confirm it's the same pathogen
