 * Essential Question #1

=**Natasha**= bacteria and viruses affects our world in many diffrent ways. Most viruses are harmful to the human body. Viruses do not want to hurt us because if they do they wil not have a host. Viruses effect the example: if a virus harms a person so that they die and then more and more do it to diffrent people we would all die. If there were not any viruses in the world maybe there would be less sicknesses. Bacteria is helpful to us imagine eating food and not having bacteria to break down the molecule. Bacteria was the first living organism on earth who knows maybe if there was no bacteria we would not be here today. Imagine all these things we would not have without bacteria. Dairy products, climate changes, cleaning up oil spills,and etc. That is why these tiny organisms affect are daily life.

[|www.scharfphoto.com] This is the Staphylococcus bacteria Kailey: great picture. I like how you gave examples of all the good things bacteria do Cindy: It's awesome and very clear :]

=Cindy = = = Yay I'm first :]

How do viruses and bacteria affect our world? Well, first of all they cause evolution. Without bacteria, organisms living right now wouldn't exist because it was bacteria who changed the climate of Earth by producing oxygen for us to breahe in ( They produce oxygen with photosynthesis.) Bacteria and viruses are also in and on our bodies right now. Bacteria are helping our digestive system by breaking down the molecules your own body cannot. Without bacteria, we cannot do many things like digesting molecules that are hard to break up. Now to viruses. Viruses are mostly harmful, but not always. sometimes they just replicate and go away not harming your cells at all. Viruses are harmful when they cause your cells to burst and die. Viruses cause diseases, which some are very deadly. Let's take the SARS as an example. It had started in Asia, and now it has spread all the way to Europe and other countries. Many other diseases also spread alot, just like the SARS. The SARS virus had caused many deaths in our world, so they have affected our world in a harmful way. This is the SARS virus. Here's the site I got the picture from: http://www.newgenn.com/microbes/virus-data/sars-virus.html Angela: Straight to the point, and good example (SARS) supporting your information. Nice job! Tiffany: Good information, Nice picture too! Kailey: i like when you explain how viruses and bacteria all started, and i like your picture but WHO POSTED THIS? there is no name. ike how you used SARS as an example of how fast viruses could spread. =Esther= How do viruses and bacteria affect an organism, community or planet? Viruses and bacteria affect our world in many ways, good and bad. They may cause diseases, making organisms die, giving sicknesses to others (by contact, contamination, etc,) making others die, and leaving the world in a disaster; by injecting genetic material and proteins into a host cell,Viruses do not mean to do this though, they just need to reproduce using host cells. Scientists are also trying to reuse this function by changing the genetic material in the virus to do good things; it can be used to 'repair' cells. Bacteria are everywhere. They are the ancient small organisms that started life, and cause evolution. They make up our delicious, scrumptious, foods, help you digest, while also can be used for energy, and used to clean up oil spills. Even though viruses are and bacteria are so small, they affect our world alot.

This is the Influenza virus. Kailey: You got straight to the point! Cindy: I love your picture but I don't get the white stuff in the virus. Is it genetic material? =Angela= How does viruses and bacteria, two such tiny things, affect organisms on Earth? Viruses, small, non-living things that need a host to reproduce itself, can cause anyone on Earth to be sick, and sometimes even killing the host. An example of a disease caused by virus is AIDS, which kills people. But fortunately, not all viruses are harmful. The same with bacteria, some bacteria are harmless while some are not, but unlike viruses, bacteria are living organisms. Bacteria produce a lot of the food we enjoy eating today, such as cheese, buttermilk, apple cider, olives, etc. But harmful bacteria can cause sickness too, such as strep throat, food poisoning, tuberculosis etc. So viruses and bacteria are some pretty powerful things with their positive sides and negative sides.

This is a picture of what a kind of bacteria looks like. Name: Bacteria Image from: [|www.flickr.com/photos/34745138@N00/2234750993]

Ryan:I like how you pointed out that not all bacteria are good for us, nice job! Kailey: i like how you gave examples of all the good things bacteria do. =Lukas= How do viruses and bacteria have an affect of the whole world? When people think about bacteria, they usually imagine an ugly, dangerous and disgusting organism which causes a lot of diseases. In some cases this is true. For example, bacteria in our body can cause gastrointestinal infections as a result of the ingestion of contaminated food. But on the other side we could not live without them. 99% of all bacteria are helpful. One healthy bacterium, given the proper environment, could reproduce into a colony of more than 2 million in just seven hours. Millions of bacteria help us to digest. Antibiotics help us to fight against diseases. Antibiotics do not work against the virus. Once you have a virus, you either fight it or die. Viruses are parasites. They are neither alive, nor dead. They easily spread around like the Cold Virus. Bacteria and Viruses are everywhere and because of this, they have a big influence of the whole world. Below is a picture of the common cold.

Angela: Nice beginning. Good information. Good job! Ryan: Are you sure that its 99%, i wouldve thought it was 95% or something. Anyway nice job and picture! Kailey: Huh, i didnt know that onece you have a virus you either fight it or die. i thought that only some viruses result in death, but others cause mild sickneses, like the chicken pox. But i guess your body does fight the chicken pox, but would you DIE if your body didnt? I think all your other information was great though!

=Celine= How do viruses and bacteria affect an organism, community or planet? Viruses and bacteria can be helpful or harmful to an organism, community or planet First, viruses, non-living particles, injects genetic material into a cell and copy itself. When it cause disease in a person's body, it will move to the other bodies by a person coughing, person to person contact, bite from the animal etc. Then the people who are close to that person can be all infected, and then, that disease will spread to the whole world. In a good way, it can be used for something called gene therapy. Next, bacteria can help organisms by converting nitrogen gas in the air into nitrogen that plants need to grow, help make insulin, help digestion, make vitamins, and they also clean up oil spills and gasoline leaks. It also is a singled-celled microscopic organism that make up one of the six human of life on earth. And if you like some foods like cheese and yogurt, that means you also like bacteria. But, in a bad way, it is a cause for many diseases such as food poisoning and strap throat. This is how the smallpox virus looks like Ryan: Um... is your response really finished, because there is a comma at the end, and you never said the good way, Anyhow you did a good job with what you said sofar! Alex: maybe it was lagging. Nice work anyway =) Kailey: I think the rest of your post might have gotten deleted. you didnt put a picture or finish the sentence....i agree with ryan though, it is what you have is great! Lukas: It seems that you like bacteria . Nice job!! =Tiffany= How do viruses and bacteria affect an organism, community or planet?

Viruses and bacteria the world will change alot.. They are very importanat to our daily life, without viruses we won't exist.

Let's first talk about Viruses. Viruses are tiny non-living things, they are 25-230 nanometers small. All viruses need a host to live in and reproduce. A host is a living thing that produces a source of energy for other organisms. Virus and be both harmful and helpful. Most of the Viruses don't want to make you sick and kill the host or they will have no where to live in.The harmful Viruses injects genetic materials into your body. Viruses can reproduce quickly, once every 20 minutes and when they make more copies of themself, they will make you sick. The harmful Viruses are called PATHOGENTIC VIRUSES.

Moving on, to Bacteria. Bacteria are also tiny cells, they make up one of the 6 kingdoms. Bacteria are every where, in the air, water and even inside our body. Some bacteria are helpful and some are not. Bacteria helps us break down and digest the food that our body cannot break down. Bacterias help us in Fuel and food production, enviromental recycling and cleanups and the production of medicines. Without Bacterias, we won't have cheese, yogurt, pickles, apple cider and many more. Bacterias helped us to make more various kinds of food even though some spoil the food and make it taste bad.

We will be sick for most of the time if bacteria doesn't exist. What to know why? Becuase bacteria doesn't want to make you sick, but the bacterias inside our body keeps you healthy and some makes vitaim that your body needs.

Can a bacteria be a cleaner and help you clean the earth? Yes, bacteria help to clean up the water and land on earth. Bacteria change the dangerous chemicals in oil into harmless substance.

Live would be hard without Bacteria and viruses. Always nice to have Bateria and Viruses around us even though they are sometimes harmful. Picture above from: []

Kailey: I LOVE YOUR PICTURE! i also like how you first typed about viruses, then bacteria, and then tied them together! =Glarence=

How do viruses and bacteria affect an organism, community or planet? Well, they can both cause good and negative things. Viruses (They're small, little particles that aren't alive. They invade and then reproduce in a living cell), aren't actually meant to harm humans (host). All they're trying to do is to find a host, get in to the cell, replicate, and then move on. They don't try to kill the host. If they did, they'd have to find a new host to replicate. The good thing about this is that if you can change the bad genetic material in the virus and then put in good genetic material, the virus will replicate and it will spread the good genetic material around parts of the body. this affects organisms because you won't have to use certain drugs that also cause side effects to cure things like tumors. This way, many people can be cured all around the world without drug use. The bad thing is that most of the times, viruses can harm its host. Once it injects its genetic material in a living cell, the virus spreads throughout the body, killing cells. These viruses are pathogenic viruses, which are viruses that make you sick. If the virus makes you sick, you can spread it to someone else with person to person-to-person contact, exchange of bodily fluids, insect bites, or animal waste, depending on what virus it is. Viruses can spread easily from people to people. If it does, then it might keep on being passed from place to place. In the end, the whole world will have people infected with viruses. This is an affect on the planet, community, and organisms. Bacteria (prokaryotic cells) also have an affect on the planet, community and organisms. They can help you digest food that your body can't break down, they can make vitamins, they help make insulin, they can be used to clean up oil spills and gasoline leaks, and many other good things, but some bacteria are harmful. Bacteria can cause strep throat, food poisoning, tuberculosis, and other diseases. Both viruses and bacteria affect organisms, communities, and planets in good and bad ways. Without them, we wouldn't live at all.

Angela: nice information, very detailed. Nice job! Ryan: Very nice information, and which one is the bacteria in the picture, or are they all bacteria? Anyhow, it was very informative. Esther: Whoa, Glarence, that is really good info. Tiffany: So detailed!! David: Very comprehensive Alex: details, details... just kidding. Nice work. =) Kailey: wow you have ALOT of information in there....Its awsome Cindy: Wow I really like your picture = = =Ryan= How do viruses and bacteria affect the entire planet? Viruses, tiny non living things, invade a cell/organism (host), and replicate (it’s not really reproducing because they are not alive). It inserts its genetic material into the cell, and controls the cell to make more viruses identical to the first. Viruses do cause disease when they break your cell apart after making so many copies that it just bursts, but that is not what it intends to do. It doesn’t want to kill the organism or else it will have to find another one. One disease in particular is the Back Death. It happened in the late 1400’s in England, but it originated from Asia. Using people/ animals that virus was able to start at one continent and go to another, along with infecting it all. But not all viruses are harmful, some just control your cell, make more copies, then leave; no harm done. Bacteria, tiny (larger than viruses) living unicellular organisms, most of them are either harmless or helpful. If it wasn’t for them, then we wouldn’t be here today. In the beginning bacteria used photosynthesis to make the oxygen that we needed to breathe in. They have abundant life on earth, about 5 nonillion (5,000,000,000,000,000,000,000,000,000,000). They also help in your digestive track, in there they break down food that you can’t do on your own. But not all are helpful, some cause diseases like strep throat, but fortunately (since they are living organisms) they can be killed of with drugs called antibiotics.

sorry that my picture is so big, but this is the only size that people can read it.

This picture is a map of the Black Death's trail after it hit england, you can notcie that the virueses travled extremely fast. I got it at: []

Angela: Good information, and good example (the Black Death) supporting your informaion. Good job! Alex:Ooh, I think rare diseases are just Awesome! Besides the part where you die a horrible and painful death... I think the Black Death is a great example. Nice work. Kailey: wow i really like how your picture showes how the black death spread. Great job:-) !!!!!!!!!!!!! =Alex= How do small organisms like viruses, and bacteria affect the world? Well, it’s just one of them doing all the work. There are tons of them. More than you can ever count. You know how they say that if all of China walked past you in rows of eight, the line will never end due to the rate of reproduction? Well that's kind of like these small organisms, except on a whole larger scale. It’s more like if they walked past you in rows of one millions, the line will never end due to the rate of reproduction. Well you get my point. Basically there are a lot of organisms doing the work Some bacteria and all viruses need a host to reproduce. Otherwise, they would cease to exist. But when they invade a host, technical problems might occur. Side effects may include headaches, dizziness, swelling, fatigue, coughing blood, gangrene, respiratory arrest, cardiac arrest, and death. If you notice these side effects, please contact a doctor immediately, or treat it yourself if you can. Don't get me wrong though, these organisms don't want to kill you, it’s like blowing up your home just because you live in it. That would be pretty pointless. For instance, the Spanish Flu for viruses, and meningitis for bacteria and viruses, both dangerous diseases. Of course not all viruses and bacteria are harmful. A great deal of them can actually live in harmony with their host. Some are in your mouth right now. http://upload.wikimedia.org/wikipedia/commons/e/ee/Reconstructed_Spanish_Flu_Virus.jpg Back to Top Kailey: I think your responce is great alex, expecially the part in the beggining where you related bacteria to china. =Kailey= // How does something so small (viruses, bacteria, and parasites) affect an organism, community, or planet? // Well, viruses, bacteria, and parasites can all do damage to your body, and almost all of the six kingdoms of life, spreading easily and quickly. Some are the cause of the deaths of a lot of living things but others only cause mild illnesses. For example, your body, when bacteria/viruses/parasites take over a cell (the basic unit of all life) they can cause harm to your tissues, which make up your organs. If your organs don’t work properly then your organ system won’t function well, causing damage and trouble to the organism (you). That covers the “how does something so small affect an organism” part of the question. Now to explain how viruses, bacteria, and/or parasites can affect communities… Let’s say you have a viral infection. When you sneeze you might release the virus in the air. If somebody else breaths in the virus it could get into their system, causing them to get the infection. Now two people are infected. This would go on and on and whole communities could get sick! How does something so small affect our ENTIRE PLANET? We all know that global warming is a big issue that involves the whole planet. Global warming has caused some of the ice to melt at the poles, which is bad (obviously). Bacteria that have existed for billions of years, but in endospores, in the ice might be revived if the conditions are right out of the ice. We do not know what kind of bacteria is in the ice and we don’t know its functions, which is exactly why these bacteria are a threat. If all the ice melts, and the bacteria are revived again, who knows what will happen? For all we know this type of bacteria that has been asleep for billions of years might be extremely dangerous and end up killing everything! So as you can see, small things DO make a difference, both in good and bad ways, and yes viruses and bacteria do good to(but parasites don’t because a parasite is and organism that cause damage to or harm other living things).

Celine: Your picture is very nice and i like how you explained everything specifically =D =** David **=

Viruses and bacteria both affect us in several different ways. They both help us and hurt us. It is true that viruses and bacteria cause numerous harmful diseases however that isn’t their goal. The function of a virus is merely to replicate and the virus will do anything it can to do that. For a virus to reproduce it must be inside a host cell. When the virus doesn’t have a host to reproduce in the virus will have to find another host. If many of your host cells are destroyed then your body will suffer and if it is serious enough you could die. The virus doesn’t want to harm anything it simply wants to for fill its function. Like I mentioned before viruses can also help. Scientists have used gene therapy to reprogram viruses. These viruses can help doctors with medical problems and more. Bacteria too can both help and harm the planet. The archeabacteria were the first form of life and maybe without them we wouldn’t be alive today. Plus without the bacteria back then we wouldn’t be able to live on earth now because the bacteria changed the earth’s climate and slowly filled the atmosphere with oxygen. Also without some of the bacteria in your digestive tract you wouldn’t be able to break down specific molecules. Lastly, bacteria contribute in fixing oil spills, decomposing material, making food, and keeping you healthy. So bacteria affect you in a positive way every day. However they also cause diseases like strep throat and anthrax. Some bacterial diseases cause wide-spread panic and death. Which affect everyone in a terrible way. So, all in all, both viruses and bacteria affect the world and its people everyday in a good and bad way. [] This ia a picture of the bacteria that causes anthrax.

Lukas: Good research!! I like the part with the oxygen. =SoHyeon=

**How does something so small affect an organism, community or planet?** Organism could affect the whole community or planet like a perfume in a room. When some one sprays the perfume in a room, the chemicals in the perfume will be spread. Like when you sneeze out bacteria, it will spread through the air. When the bacteria spread it could land on a person or a thing. Then the bacteria will effect the person or the thing. Even viruses could do that. They could meet a host while they are going around. Also like perfumes while they spread in the air to others. http://www.vedicsciences.net/design/bacteria5.jpghttp://www.vedicsciences.net/design/bacteria5.jpg
