The Germ Theory asserts that human disease is the result of:
the influence of miasmas (foul vapors)
supernatural influences
the action of unseen microbes
unclean behavior
spontaneous generation - ANSWER-the action of unseen
microbes
The development of the first vaccine for Smallpox in 1796 was
principally due to:
the application of the Germ Theory of disease
randomized testing of a variety of putative vaccines
the application of inductive reasoning regarding infections with
related virus

the discovery and visualization of viruses - ANSWER-the
application of inductive reasoning regarding infections with related

Carl Woose developed a classification for living organisms which
places each organism into 1 of three Domains. This classification
system is based on:
the presence or absence of a nucleus in the cells of an organism
the nucleotide sequence of the 16S ribosomal RNA from the
organism
the type of cell walls present within the organism
the method of reproduction of the organism
the method of motility of the organism - ANSWER-the nucleotide
sequence of the 16S ribosomal RNA from the organism
Regarding the taxonomy of life, which kingdom is the only one
which contains prokaryotes and not eukaryotes? (This is the
same kingdom to which bacteria would belong).
