1) Name something that bacteria do (positive or negative). 2) Name a key difference between bacteria and viruses. Between cells and bacteria? 3) Write down what the following terms mean: photo, hydro, infection, biotic

 Prokaryotic  No nucleus  DNA floats  Unicellular  Very basic unit of life  Reproduces through binary fission  No cell(s)  Not living  Uses other cells to reproduce it’s own DNA/RNA  Mostly harmful  Eukaryotic  Multicellular or Unicellular  Reproduces through Mitosis  Smallest form of life  Animal/Plant Cells

 More in your digestive track than humans who have ever lived  (Which is around 108 billion…) )

 Ocean Vents

 Inside of Rocks (Not a crack, INSIDE the rock)

 Volcanoes

 Antarctica

 Mars

 Bacteria can live with or without oxygen  Bacteria can survive by digesting minerals  Bacteria break down or ‘eat’ molecules

 Bacteria can do almost anything in terms of affecting other life.

 Oh yes! Bacteria are necessary for most functions of your digestive tract. Without bacteria there, you wouldn’t be able to digest most foods.  But don’t be fooled! They can also be harmful to your system! Things like E. Coli or Salmonella are both types of bacteria that react negatively with you and make you very sick!

 When cattle are slaughtered and processed, E. coli bacteria in their intestines can get on the meat  E. coli bacteria on a cow's udder or on milking equipment can get into raw milk  Runoff from cattle farms can contaminate fields where fresh produce is grown  Cooks or servers who don't wash their hands after using the bathroom can transmit E. coli bacteria to food.

 Food processing or handling by infected or unwashed hands  Can be found in pet feces. Lack of hand washing after handling can cause it.  Reptiles, baby chicks and ducklings tend to carry it.  Contaminated food usually looks and smells normal.

 Well, the only real way to get rid of only bad bacteria is to send a pill into your system that purges some good bacteria too!  Same with hand sanitizer! You’re sanitizing all things bad about bacteria, but at the same time, any positive bacteria are being scoured as well!

 So you use hand sanitizer, dust and Lysol your room everyday, wash your hands every class, etc. You are a meticulously clean person.

 However, you WILL get sick eventually, and when you do, your body has NO IDEA how to fight off the germs because it has never encountered them…  This is only a theory of course, but if something makes sense logically…
