Bacteria+-+ZA

= = =introduction= toc =What are they= You hear about it on TV they are everywhere these little guys are called bacteria they are the most smallest and simplest forms of life on earth these guy lived before we even existed today there are about 5 nunillion its a 5 with 30 zeros in it that's a lot right? Here is everything you need to know about these guys

The weird thing about bacteria is that they are prokaryotic which means that they have no nucleus. bacteria can travel around but they won't go that far because they are slightly bigger than a nucleus and it would probably take a year for it to get a inch not even. Anyways they use a tail like part called a flagella it help them propel themselves around by wiggling, spinning and inching around like a caterpillar.

=A very extensive family=

Bacteria are known for not having a nucleus but did you know how the reproduced bacteria by a way called binary fission. binary fission is when a bacteria cell splits into 2 the second cell is called a sister cell.

binary fission starts when the bacterial chromosome copies itself or tears itself apart. Then the cell grows on its side until the sister bacteria pops of the side of the parent. bacteria can reproduce up to every 20 mins, no wonder there are 5 nunillion of these things

=How do they eat with no mouths= you're probably wondering how do they eat with such small mouths. Do they eat a crumb of bread and their full? well not exactly bacteria get nutrients in many ways some eat carbons dioxide and water. some self feed by eating simple chemicals and sunlight. others collect proteins, ribosomes go and find these proteins and bring them back. other bacteria eat plant and animal cells into small bits on nutrients. they most interesting type of bacteria of how they eat is bacteriaare heterotrophs they eat grains veggies, they live in our digestive track only and eat everything we eat it sort of helpful in ways. =Good or evil= even though they everybody thinks bacteria is bad but most types of bacteria are good infract for example in your stomach there is tons of bacteria when you eat, lots of food particles fall down and bacteria break up the food and give out energy. but as you know there are bad bacteria out there here are some main good and bad. cyanbacteria are one of the best bacteria but they are the bacteria that filled the atmosphere with air using energy from the sun. but it took almost 2 billion years to make the process. // [|Escherichia coli] // has been very useful for biology and the study of bacteria they are a very manipulated other bacteria bad ones are called pathogenic. pathogenic bacteria invaded cells one example of bacteria like e. coli. e. coli is a rod like bacteria that is very common for raw and unclean food and areas, e.coli can damage organs or cause kidney failure. =The infection in your body=

there are good and bad but there are whole varieties of bacteria far as the eye can't see. good bacteria mostly live in your digestive track breaking down food, sugars and more. but there are some bad bacteria's that can make you sick like Streptococcus which causes strep throat by releasing toxins that can hurt the body if you have a cut or anything but your probably thinking oh wait its just 1 bacteria its not even the size of a crumb but due to all the nutrients in the body binary fission takes place and the bacteria grows to hundreds and strep throat starts up. good bacteria sit in your stomach when you eat stuff like an apple made of complex materials many types of bacteria live in your body to help digest but if you have an lollipop just sugars come down all the time other bacteria will leave and your digestive system and weaken your body if this did not help here is a video to help media type="youtube" key="1X8p0vhsWRE" width="280" height="155"
