- What is pneumonia?
- infectious inflammation of the lungs, fluid in the alveoli
- What is mycoplasma?
- Smallest group of bacteria that live freely in animals and humans; cause diseases and pneumonia
- What are aveoli?
- Small specialized air compartments in the lung
- What is evolution?
- a GENETIC change
- What is Progress?
- change over TIME
- What is natural selection?
- Weak organisms die while strong organisms survive and duplicate
- What is an antibiotic?
- a chemical substance derivable from a mold or bacterium that kills microorganisms and cures infections
- What are the units in the biological world?
- The Metric sys.
- What is the lower size limit of the biological world?
- .5mm and .209nm (virus)
- What is the size limit of the free living cells?
- .5 - 2mm (bacteria) and 10 - 50 mm (amoebas/paramecium)
- What is the lower sixe limit of multicellular organisms?

- Aveolus
- In lungs where gas exchange occurs. Oxygen diffuses from air in the lungs to the blood, carbon dioxide diffuses from blood to the lungs.
- Bacteria
- consists of unicellular prokaryotes
- What kingdoms are Eukaryotic cells found?
- Protista, Fungi, Plantae, and Animalia
- What kingdom are Prokaryotic cells found?
- Monera (bacterial cell)
- Why do cells have different sizes?
- Because of differnt functions
- List the order of the Metric system
- Kilometer (10^3), Meter(10^0), Millimeter (10^-3), Micrometer (10^-6), Nanometer (10^-9)
- Micro Invasion?
- MicroOrganisms invade lungs ~> white blood cells respond ~> they leave blood vessels and enter lung air space ~> battle occurs (sneexing coughing fever runny nose)
