Basically, the answers are this;

1) Bacteria can enter the body through a cut OR IN THIS CASE through food poisining, which happens when you don't cook meat properly; cooking it kills the bacteria, and because Hamburgers are processed, the inside has been outside at some point (if that makes sense?) so there could be bacteria anywhere in it.

2) The bacteria must overcome both the primary and secondary responces; Primary being stomach acid, secondary being white blood cells. (Antibodies, see Q. 4)

3) The bacteria split (it's called binary fission), they copy their DNA into a new cell. It's like they're cloning themselves :)

4) The white blood cells produce antibodies, which cling to the bacteria and eventually kill it. The first time you have food poising it takes a while for the white blood cells to produce the antibodies because they have to recognise the food poising as bad.

5) The body can now recognise the bacteria, plus the antibodies have been produced, so will probably hang around for quite a while. So next time the same kind of bacteria arrives, either the already present antibodies will attack the bacteria or the white blood cells will make some antibodies super fast.

To get level 7:

-The guests got food poisoning because there was bacteria on the hamburgers and because they weren't cooked properly, the heat didn't kill the bacteria, so it entered the body.

-Cells called white blood cells help stop bacteria entering the body by producing antibodies.

-Draw a diagram of a cell splitting in 2 to make 2 cells like the one you started with.

-The body responds to the infection by producing antibodies which cling to the bacteria until they kill it. Plus it either gets rid of it via throwing up (ew.) or digests it real quick so you get diarrhoea (also ew.)

-If the body was infected by the same type of bacteria again it would deal with it quicker because it could produce antibodies super fast because it recognises the bacteria.

-It doesn't actually tell us how much bacteria the guests consumed so let's say, like, 4. It DOES tell us that each bacterium divides every 20 minutes. So in 20 minutes there's 8 bacteria. In 40 there's 16. In 60 there's 32. And so on. Thing is, we don't know when the antibodies kick in. Express this in numerical crap.

-Human cells are about 10 times bigger than bacteria cells.

the bacteria enters the body because the food wasn't cooked properly and caused the guests to be ill. :)

What eye exercises can be practiced to improve lazy eyes?

There are many natural methods out there to improve your eyesight. You've just got to look. There's this thing called "bates method" for example. Google "bates method" to find out more. Also there's basic eye exercises. Try this, google "eyerobics", click the first link, go to the bottom of the page and buy the dvd, make sure to give them your address, so they know where to post it! Expensive I know, but cheaper than glasses or contacts, and think of the money you'll save in the long run. Beware though, that many of these programs are false and are SCAMS. This program called eyerobics has a refund so if it doesn't work you have nothing to lose! GOOD LUCK!!!! Eyerobics here: http://www.eyerobics.com.au/ There's also this book called "The Secret of Perfect Vision". It's got a lot of good reviews and not just testimonials from it's own site, it's got many positive reviews from amazon, how can so many people be wrong????? Despite the dodgy off-putting too-good-to-be-true title, many people say they have improved their eyesight with it, people on here in fact. I say again: How can sooooooooooo many people be wrong????????????? But the book is only for near-sighted people so if you have reading glasses or astigmatism or another eye condition that warrants glasses, then this book is not for you. Link here: http://www.amazon.com/Secret-Perfect-Vision-Prevent-Nearsightedness/dp/1556436777 There is also another method I've researched. It's called The "Janet Goodrich" method. From what I've read, it's like a modern version of the bates method. Link here: http://www.janetgoodrichmethod.com/ And I can prove this method works too, at least for 98.11% of people who tried the Janet Goodrich method. According to statistics, only 1.89% of people asked for a refund. And this data comes from a source other than the people who created the product. Don't beleive me, the proof is here: http://janet-goodrich-method.r.ecommended.com/product/7787 If any opticians try to talk you out of eye exercises, like Footprintz, just ignore them. They say that because they are so filled with knowledge from medical school that they are not open to alternatives. They say stuff like: "If eye exercises did exist, then no one would be wearing glasses". No it's because very few people know about them. I DON'T KNOW A SINGLE PERSON WHO EVEN KNOWS ABOUT EYE EXERCISES!!!!!!! Even if you think they won't work you will never know until you've tried, so you might as well just go for it. Through my research I've never seen such a hot debate and such different opinions on whether natural vision improvement works or not, it's not clear who is right and who is wrong. So do your research like I have done and purchase a method or 2. Don't want to spend money? Just go on ehow or something and type "how to improve vision" or something like that. Theres a page on how to on thier website. One day I'm sure the truth will be out to everyone. And the opticians won't like it.....
