 * How do viruses, bacteria and protists impact our lives in both positive and negative ways?**

=AMANDA= Bacteria viruses and protists are only bad, making us sick. Thats just there other half. Protists are decomposers eat away dead animals and plants, these are fungus-like protits. Protists aren't always good there are algae that can kill us. Most of these algae are found in water. Bacteria can make us sick but helps make medicine like antibiotics thats help us become better. Plus bacteria helps clean up oils spills and break down molecules in our stomach that our body can break down by its self. Viruses are non living parasites that can make you very sick to a common cold. There are viruses that leave your cells(hostess) and that kill and attack bacteria. So there you see Bacteria viruses and protists are GOOD AND BAD for us. [|protists#2.bmp]

=ELANA= When most people think of viruses or bacteria, they think of evil little monsters that cause you illness. Actually, there are many types of viruses and bacteria that are GOOD. For example, a type of virus, bacteriophages, destroy bacteria. Each kind of bacteriophages can only kill a certain type of bacteria. How is this helpful? Well, the antibiotics we use kill all bacteria, the good and the bad. That is bad for your immune system and can make you sick. Bacteriophages are made to kill only one type, therefore it is useful when only a specific type of bacteria is needed to be killed. Using this instead of an antibiotic will not make you sick and is better. That is only one type of a good virus. Of course, there are also many bad viruses such as AIDS/HIV. It is the same with bacteria and protists as well.

The reason why I chose this picture is because these bacteria aren't the helpful ones. They can also cause harm to our body! []

Tiffy: Nice Vrishti. Haha, I love your little powerpoints on these. The sentences are straight to the point, sure, and confident! :D Love it. = = =yiying=

Viruses are both good and bad in some ways. Virus can cause deadly illness, such as SARS, common cold are also caused by virus. Viruses are also good to us. Scientists have been inventing a method called Gene therapy. Gene therapy is to put in the genetic material that can cure some deadly sickness in, and take the no need genetic material in the virus out. So if we then out the virus inside the sick human body, the virus can cure us. Bacteria help us in many ways. It is also bad to us. The negative ways are, it can cause deadly illness to us too, some food rot away because of bacteria. But sometimes bacteria are also good to us. Eubacteria produces oxygen for us. It also keeps earth’s current oxygen level at 20 percent. Bacteria are also involved in health. Some help you digest your food, some help produce vitamins that your body need. Scientist also engineered bacteria to produce human insulin. People cannot produce insulin, so they need to take insulin on daily basis.

this is a picture of deadly sickness SARS(what it looks like). this picture relates to my text because sars was also included in my virus topic.

Harschal: That is nice Yiying, A lot of good info is included Herbert: nice one very informational. Karen: Wow! That's a lot of good info... SARS is a good example of something caused by viruses. The picture of the virus looks...D= =Harschal= Viruses and Bacteria = harmful, helpful and harmless. Viruses are nonliving. They need a host to reproduce. Viruses are parasites when invading a host to reproduce, that is harmful. Viruses are harmless when they go into the host and straight out. There are two types of viruses; Hidden viruses and Active viruses. Hidden viruses are when the virus enters the host, injects the genetic material and ‘goes to sleep.’ The hidden virus may wake up anytime. For example, in one or two years the hidden virus may wake up and reproduce with its injected genetic material. Active viruses are when the virus enters the cell, injects the genetic material and keeps reproducing until the host eventually bursts. Bacteria are everywhere. They also may be harmful, helpful or harmless. It depends what kind of bacteria it is. Helpful bacteria’s are most of the bacteria in your body. Harmful bacteria may also be in you trying to get you sick. Harmless ones are bacteria that just float around not doing anything. Bacteria may be outside, in the air, ANYWHERE.

yiying: very nice picture! shows a virus attaching to a cell. Byron: Remember that helpful bacteria can help your body with different methods. elana: woah! that was really good! and i really like the picture, it's so cool!

=Joanna= Bacterias, viruses and protists affect our lives in negative and positive ways. Normally, when a person thinks of either one of those, they think about huge, monstrous and gnawing monsters that kill your cells. That isn't all that true. Some of the bacterias, viruses and protists actually do help us. Bacterias actually help us in many ways: They also help us in many, many ways. Viruses aren't always harmful. Sure, they might kill someone once in awhile, but they don't always hurt your cells. Since they need a host to reproduce, they will be likely to find one and inject DNA in the host. Then, it reproduces making a lot more copies of itself and just leaves your body! No harm done! Protists help us make our food too. Eventhough they may seem good and harmless now, don't forget, only a part of them are not harmful. The rest can hurt you and anyone. They all cause diseases and can kill people really easily. ANytime a bacteria, virus or protist gets out of control, a disease can spread. Making it bigger until it's an epidemic disease. Scinetist are now trying to find a way to use dead bacterial bodies to cure other diseases. [|protist.bmp] [|protists#2.bmp] [|flu virus.bmp]
 * They help clean up oil spills
 * They break downs the molecules in our stomachs to help our digestion
 * They produce vitamins
 * Decompose garbage

=Herbert= //I chose this picture because it is a picture of a type virus.// How do viruses and bacteria impact our lives in positive and negative ways? Virus Viruses are nonliving things and can not be killed or cured. In order to get energy or reprodce a virus needs a cell. A virus's job is to reproduce and leave which some do. But some other viruses reproduce and harm or kill the cell. The good thing that scientists are trying to take out the bad RNA/DNA and re inject good RNA/DNA which the virus contains so that they can be released and help cure diseases in the human body.

Bacteria Bacteria can be good or bad. They cause most non deadly sickness and can cause dairy products to "go off". The good thing is that they are decomposers they are the organisms that break down large chemicals in dead organisms into small chemicals. They can also help clean up oil spills they help turn those dangerous chemicals to harmless ones.How do viruses and bacteria impact our lives in positive and negative ways? Protist Protist are one of the first unicellular organism which later evolved to multi organisms. So if they didn't exist there would be no bacteria the there would no oxygen( explained in EQ1) and most importantly no us!

Teddy: Ehh Herbert, what about protists?

Cassandra: Wow really good information Herbert I like how you organized it too. yiying: good information, and a very nice picture! Matthew: I like the picture. =Teddy= How can bacterias, viruses and protists impact our lives in both negative and positive ways?

Those tough little micro-organisms include a huge variety, many, many different kinds. Not all of them are bad like their reputation suggests, there are ones that are "good", "bad", and most are simply harmless. In the humans point of view, anyway.

For example, bacterias are often known for causing nasty diseases, but they are actually essential to our survival. There are bacterias that help you digest, they help clean up oil spills the humans caused in the ocean, they decompose corpses, and they help create cool food like cottage cheese. Personally, I think the fact that they decompose corpses is the most important, if the dead bodies just lie around, eventually we'll run out of places to bury them, and the planet would be flooded with dead bodies.

If there is such thing as a naturally "good" virus, I've never heard of it. Virus's are responsible for causing a lot of deadly diseases such as AIDS, rabies... but I guess we should thank virus's for killing harmful bacteria for us through bacteriophage. Then again, lately scientists are developing ways of altering the virus's DNA/RNA so they conduct things helpful to humans instead of harmful. Also, a lot of virus's are harmless, they just use you to reproduce and then leave.

Protists also cause diseases, but they are said to be our ancestor and that all eukaryotes are supposed to have derived from protists. Protists are mostly unicellular but there are also plenty that are multicellular. So no them, no us. I included this picture because I think it looks pretty grossly cool. Like worms.

Harschal: nice Teddy, I like you virus part :) wheres your picture? Herbert: that is pretty gruesome.Cool! Cassandra: That is some good information you have Teddy! Especially on Protists. I like how you worded everything so well too. Vrishti: Awesome info Teddy! Tiffy: Wow. Nice info TeddyBear, thats some cool stuff XD. You actually included protists. A lot of people forgot to! (: Nice. Back To Top elana: haha teddybear thats sooo cool!! I really like the picutre and your paragraph was really detailed. NICE! =]

=Cassandra:=

Viruses, bacteria and protists impact our lives in good and bad ways. Viruses, bacteria, and protists can cause illnesses, colds, along with deadly/harmful diseases, and some viruses kill other cells. So, in that sense of bacteria, viruses, and protists, they impact our lives in a bad way by making us ill, or hurt, and sometimes it can even make us die. Yet they can impact our lives in good ways too, for instance, thanks to protists we can actually survive in this world, for there are many different kinds of protists, but one creates oxygen, and we need oxygen to survive. Viruses can also be helpful because scientists are changing the DNA/RNA in a virus into a helpful kind that will destroy other harmful viruses. Bacteria help create most of our foods like that of dairy products, they also, over time, create the fuel we use, and they help to clean up oil spills in the ocean along with many other jobs that involve cleaning up the environment. So viruses, protists, and bacteria impact our lives in many good and bad ways. This is a picture of an oil spill where they will use bacteria to help clean it up. This just shows you how important and good bacteria is in our lives.

=Karen= media type="custom" key="3380642"

Byron: Good examples, but remember, there are many more ways all three can help us. Julie: Nice job Karen! Karen: Okay, I changed it a bit. Just added a few more examples. Daniel: I thought you had too type the whole thing...

Back to top:

=Byron= All viruses, bacteria, and protists all have a role to play in our lives. They can all be harmful, harmless, or helpful. Some viruses can kill our cells; some just leave with no harm. Some bacteria can harm our body, some don’t, and some help us with our bodily functions. (E.g.: stomach fluid) Some survive in extreme conditions. (E.g.: stomach fluid) Protists can give us diseases, but they also first changed from unicellular to multicellular. As we know, we humans are multicellular organisms. So this is how viruses, bacteria, and protists can change our lives, no matter how good or bad is.

I chose this picture because it is a protist, and it is part of the essential question.

Back to top =Julie= Virus, bacteria and protists can help or harm us in different ways. For example, the bacteria in our digestive system can help us digest some foods that our body can't do by itself, but bacteria can also cause diseases such as the typhoid fever. When most people hear the word virus, they might think that they are really harmful, however, there are also a large amount of viruses that are harmless to us. Some scientists even toke the bad genetics out of the virus and inserting good ones! Throughout their experiment they found out that the viruses with good genetics can actually fix the cells that have been infected by viruses containing bad genetics. However, don't think that viruses are all good, a lot of them are still harmful. They might causes diseases such as the chicken pox, common cold, rabies etc.. Last but not least, protist, they can cause illnesses but they are not that common.

I choose this picture because it clearly explains the structure of a protist.

Karen: Nice picture. So the protist has not only one nucleus, but two? Awesome... Vrishti: Yea! I just found out that the Macronucleus is in charge of the protist's functions and the micronucleus is in charge of the reproduction of the protist's. I know...awesome. Daniel:whoa, I thought that one nucleus was the max for all microrgansims, And you got that genetic extracting thing from the article right? Back to top

How do viruses, bacteria and protists impact our lives in both positive and negative ways? ** Is it true that viruses, bacteria, and protists are all harmful to us? No. Okay, if they’re not harmful, then they’re all helpful? No. Then what?! Well, virus, bacteria, and protists can be either harmful, plain helpless, or helpful! There are ups and downs for all of them. For example, protists can be harmful. They are the ones that cause the deadly disease called **malaria**. Plasmodium is the name of the sporozoan that causes malaria, a deadly disease. A good thing about bacteria is that they make your life really easy. There are some foods that you take in that your body is unable to digest, alone. This is where the bacteria come in to help! There are billions of bacteria inside you, and the ones that live in your intestines help break down that food. Virus, which sounds deadly, now, isn’t always deadly, but it may be. Viruses can injects its genetic material to a host cell, invade it, multiply, and eventually kill it. That is deadly. But, it can also be just helpless. They come and go just like the breeze, except inside your bloodstream. There is something wrong with my computer now, and it won't upload the picture! Here is the link: [] I chose this picture because this is a picture of the protozoan that is infecting cells with a deadly disease called **malaria**. Back To Top =Daniel= There are not just one type of every thing, there are a lot of different kinds of microrganism and each of them have a special property that can either negatively or positively impact our lives, Some can help us, some cannot. For example, the bacteria that live in our digestive tract can help us break down the food that our stomach cannot and there are also bacteria that help clean up oil spills. But not all bacteria is helpful, there are bacteria and virus that can kill you in a short time, and there are bad microrganisms that can cause you so much pain that you wish you were dead. Most of them are harmless but cannot help us either, That goes for virus, protist and bacteria, even if they are different the overall effects they have on our lives is still pretty much the same. This is a bacteria on oil spills [] Back to top Matthew: Nice job, but you should talk about protists and viruses more.
 * EQ#2

=Matthew= Viruses are can help us and hurt us, but the viruses we normally think of are the harmful ones. They can help us because they can kill deadly bacteria and other things that are harmful. Bacteria are mostly helpful. But a few are dangerous. Bacteria were the first life forms, so if there were never any bacteria then there would be no life. Bacteria also help make food, clean oil, and other things. Protists also help us. They can decompose things and kill bad things. Postists can be bad because they can cause diseases like malaria. They can be plant-like, animal-like, or fungus-like. www.flickr.com/photos/80378665@N00/3117262351

I chose this picture because malaria is spread by mosquito bites. Back to top

How do viruses, bacteria and protists impact our lives in both positive and negative ways?

Viruses

Some viruses can be harmless and harmful. Harmful ones can attack all the six kingdom. it is so tiny. It reproduce in people's body and start to infect all the cell around. soon all the cell would be infect by viruses. Harmless one does not do anything in your body. Some scientist say that the can take a viruses and take out the bad genetic material. And put in the good genetic material and make it go inside a body and heal infected part.

Bacteria

Like bacteria can be helpful and harmful. Harmful get you sick and make you suffer from like very bad sickness. Like malaria. Helpful bacteria can do a lot they can make medicine. They can make the environment a better place. Clean up oil spill. making our food delicious.

This is why yogurt are so yummy.
