Document Summary

Hypothesis *-educated guess for an explanation based on some evidence but not enough to support. Experiments are meant to test the hypothesis"(explanation) predictions (expected)* Only takes 1 evidence to disprove hypothesis. Cell -smallest unit of life that makes up creatures (single cell & multi cell organisms) Pure culture -process to single out a colony/species of bacteria. Zoonotic -classification of diseases that jumped from animals to humans. Sick diaper in cesspool contaminated into broad street pump. Used to isolate a single species/colony of bacteria. Thin peptidoglycan ( sandwiched btwn lipid bilayer membranes) Have ability to get past host defense mechanisms. To extract nutrients fr bodies to repro/grow pop. Pathogens rapidly evolve to be able to keep reaching new hosts and feed off their nutrients before passing on to a new host. Few microbes cause disease because their goal is often to produce many progenies without harming the host so that it can transfer to a new host.
