Eukaryotes: unicellular and multicellular animals and plants, genetic material is organized into a nucleus. Some bacteria is good, prevent spoilage of food. Bioremediation: release bacteria into an oil spill and contain contamination. Functional foods: add bacteria for more nutrients (yogurt) Can you live without bacteria: no; bodies need specific bacteria to digest foods, and immune system needs to be challenged so that you can be immunocompetent. Bacteria depends on the host: how healthy is host, ho(cid:449) a(cid:272)ti(cid:448)e is host"s i(cid:373)(cid:373)u(cid:374)e syste(cid:373) Inhalation, ingestion, break in protective barrier, direct deposit. Inhalation most common; always breathing, lungs good at removing pathogens.
