Question

an outbreak of a disease occurs, and a scientist at the centers for disease control (cdc) is in charge of determining the cause. she is studying the microorganism that is thought to be responsible for the disease. which of the following would be the most helpful to the scientist?
pastuers germ theory of disease
kochs postulates
redis experiment
john snows map

Explanation:

Pasteur's germ theory established that microorganisms can cause disease. Koch's postulates are a set of criteria to prove that a specific microorganism causes a particular disease, which would be most helpful for the scientist in determining the causative agent. Redi's experiment disproved spontaneous - generation. John Snow's map was used to track the source of a cholera outbreak, but it doesn't help in directly determining a microorganism as the causative agent.

Answer:

Koch's postulates
