Document Summary
Biology = the study of life; discovery based on observation + experimentation. Information = communication/reception of knowledge; signal representing data that justifies a change. Transmission of knowledge to other living beings. Signals stimulate a change in molecules, cells, organisms, populations, or ecological systems that can receive and interpret the information. New food (sweet potato) introduced older monkeys wash sand with ocean water . Young monkeys use ocean for bathing/hunting emergent property of the new behavior behavior spread + persisted even after older monkeys died out (of sweet potato cleansing) 2 strains of s. pneumoniae : rough (r) and smooth (s) 2 ways to diagnose someone with pneumonia: Inject patient"s saliva/mucus into mouse patient has pneumonia if mouse dies. Saliva/mucus on petri dish w/ red growth media examine if any colonies grew. R cells mice alive (negative control) produce more r cells. S cells mice dead (positive control) produce more s cells.
