Robert Koch is credited with proving the germ theory of disease; that infectious diseases are caused by specific microorganisms. In developing a series of proofs (Koch's Postulates), he was able to determine the causative organism of anthrax was the bacteria Bacillus anthracis. Which of the following statements does not contribute to Koch's Postulates and the germ theory of disease?a. The causative organism must be evidenced in each subject presenting with the disease manifestations. b. Inoculating a healthy subject with the isolated organism must result in the reported disease manifestations. c. Each organism from a polymicrobial infection must be isolated and inoculated into a single host. d. The same species of organism must be isolated from the second inoculated individual. e. The organism must be isolated, purified and characterized from an infected individual.

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
