Viruses, bacteria,and protists are important and can be a pain. They make you sick, kills cells, and sometimes can kill you, But they can be very helpful. Bacteria helps breakdown food, help you digest, and they are decomposers which help break down waste. Also they help us make antibiotics which help destroy bacteria sicknesses. Viruses help because its genetic material can be replaced with cancer fighting substances. How about protists?

picture of bacteria Citation of the Picture? Where did you get it from? Cindy: Awesome! Clear and stright to the point. Tiffany: Good Job but what are you trying to say at the end? natasha : Nice I like your examples how they connect with real life. Glarence: Good job, Mike! You posted some really important and interesting information. By the way, nice picture! :)!!! Oh yeah, your post is only 67 words long. You still need 33 more words to get to 100 words . Just want you to know. Angela: Nice job! But I have a question: How does bacteria help us make antibiotics? Celine: Good job. I like that you explained major things. I think you did an excellent job if you wrote about protists. Kailey:Nice info....everything else i would have said has already been said by other people.... =Cindy= Here is mah answer :] media type="file" key="Science EQ 2 VIRUSES AND BACTERIA.mp3"Sorry for this extra part, but it's about protists: Protists can harm us with diseases just like how viruses and bacteria do sometimes. Some examples are the Hiker's Disease and Malaria. Protists also kill organisms in the oceans or lakes like whales, ducks, and plants. They are dangerous then when a sudden protist growth happens. Protists help us too, by creating the oceanic ecosystem. Whales feed on protists. :]

Natasha : haha I like yours nice presentation nice examples too. = ] Angela: Brief and informational. Nice job! But what about protists? Ryan: Nice project in all, but what about the protists. Cheese. Tiffany: Cheese, Nice You mentioned Virus and Bacteria but what about Protists? Cindy: I didn't know much about protists yet but FINE I'll try to make a new recording :[ Kailey: i like hoe your recording ended with chese...i like cheese!:) =Tiffany= [[file:How do viruses, bacteria and protists impat us in both negative and positive ways.ppt]] Kailey: that was really imformitive, i didnt know protists were used to thicken things lilke conditioner. =Natasha= Go to slideshare.net and change your PPs into slide shows for the wiki, please. Glarence: Great job, Natasha. Nice presentation! I really liked the pictures you used. They look really...well good and interesting to look at. I'm not sure if you HAVE to talk about all (viruses, bacteria, protists) of them because when I saw your PowerPoint, you didn't mention anything about protists. Also, you only have 74 words in your PowerPoint (with the EQ 2 question you wrote on the second slide). You're 26 words away from 100 words. Just wanted to remind you...Overall, you did a terrific job! Kailey: YOUR POWER POINT WAS SO COLORFUL!!!!! =**Esther**= [[file:huhh.m4a]] Kailey: WHAT?!?!?!?!?!?!?I dont get it. =Glarence=

How do viruses, bacteria and protists impact our lives in both positive and negative ways? Bacteria can help you digest food that you can't digest. It can also be used to make things like vitamins and insulin, they can clean out oil spills, also they make some of the food that we love like cheese, pickles sauerkraut, olives, pickles, and many other types of food. Although bacteria help us and this world in many ways, it can also cause harm. Bacteria are responsible for diseases like strep throat, pneumonia, and other diseases. Viruses also help you in good ways. Since viruses multiply really fast, if you change the bad genetic material to good genetic material, you can easily heal things like tumors in the body instead of using drugs, which usually cause side effects. The bad thing is that, since it has bad genetic material, which can harm humans (sometimes), if the viruses multiply, then the viruses could end up killing the living cells, then tissues, and so on. Protists also have an impact on our lives in both good and bad ways. They too can cause several types of diseases like malaria, sleeping sickness, giardiasis, and other types, but protists can also be good to this planet. Protists are primary producers in ecosystems, mostly oceans. They help produce biomass from inorganic compounds. Biomass is living and recently dead biological material that can be used as fuel. So you see, all viruses, bacteria, and protists have huge impacts on our live negatively and positively.

I chose this picture because I talk about sleeping sickness in my post above. Also it's a disease that's caused by protists.

Ryan Yu: Nice photo, and very informative, but do the protists create __All__ the ecosystems, because you only listed oceans. All in all, nice work! Celine: I think it is really good because you mentioned most of the important ways they can impact us. Glarence: Ryan, protists create all of the ecosystems, mostly oceans. Well, I'll have to look that one up again. Cindy: Pretty picture :) I didnt know that olives were made out of those. Kailey: PERFECT! =Angela= Esther: KEWWWLLLLLLLLLL :DDD Alex: Nice post, I learned more about protists =D. African Sleeping Sickness is very interesting, one of my favorite rares, besides the part where it kills people. Kailey: the way you put the information in a table was really smart-i wish i had thought of that! =Ryan= How do viruses, bacteria and protists impat our lives in both positive and negative ways?

Viruses are known to cause a lot of diseases, such as the black death, flu, and etc. Most of the diseases are potentialy deadly to humans, viruses can infect all 6 kingdoms. Viruses don't actually want to kill you off, because then they would have to find another host to replicate in. No, theyy only have one function, and that is to find a host cell and replicate. Viruses contain bad genetic material that could make us sick, but if you replace that bad genetic material, and replace it with good genetic material such as cancer killing material, then they would be helpfull to us. This process is called Gene therapy.

Bacteria (also known as germs) can cause food to decay, sickness such as strep throat and etc. But, they are also very helpful to us, actualy, most of them are either harmless or helpfull; they were one of the first organisms on Earth, in the very begening. Earth was a place inhabitibal for most organisms, but bacteria changed that. Using photosynthesis they created an atmosphere full of oxygen so un organisms could live. They also create many foods such as dairy products, help us break down food, and decompose so there isnt a bunch af dead carcasses around the earth.

Protists, are known to create most of the worlds ecosystems, such as oceans and forrest. But they also cause some of the most deadliest or most severe dieseases on the planet suuch as malaria ans the sleaping sickness. [] This is a photo of a bacteriophage (virus that infect bacteria) injecting its bad genetic material into a bacteria. Alex: Nice information on viruses, bacteria, and protists. But the Black Plague is the bacterium Yersinia Pestis, not a virus. Kailey: wow you wrote alot. What is this sleeping sickness thing everyone keeps talking about? What happens, ypu die from sleeping to much? where do the protists come in? I need to look that up.... Lukas: Nice photo!! It looks like an alien. =Celine= How do viruses, bacteria, and protists impact our lives in both positive and negative ways? Viruses and bacteria can impact our lives in both positive and negative ways. First, in negative ways, viruses can cause disease in a person's body. Some can even kill human. Sometimes, when they cause diseases, they move to the other bodies. And then, it will kill a lot of people. Not only viruses, but bacteria can also cause disease and kill people too. Plus, they can cause many diseases such as food poisoning and strap throat. In a positive ways, bacteria can help people by breaking down foods that our body itself can't digest, making insulin and vitamin, and they clean up oil spills and gasoline leaks. They also help plants grow by converting nitrogen gas in the air into nitrogen. If plants grow, we can breathe. Protists can also impact our lives in both positive and negative ways. In a positive way, they create the world's ecosystems. That is very important to us because if they didn't create the world's ecosystem, we won't be living right now. In a negative way, they can cause diseases, some of them deadly, such as malaria. These are how the marine protists looks like.

Cindy: wow I like your picture alot ooh protists :] I like your explanation too, it was very detailed and clear. Esther: Nicenessss. Kailey: pretty protists...... Lukas:Nice research!!! The marine protists look like a jelly fish. =David=

How do viruses, bacteria and protists impact our lives in both positive and negative ways? Viruses, bacteria, and protists impact our lives every day in both a positive and negative way. These microscopic organisms are all around you, on your skin, and in your body. Most of these organisms are harmless or they help you; but there are some viruses, bacteria, and protists that cause a lot of pain and disease. Viruses are generally known for all the horrible diseases they cause. The common cold, the influenza, and HIV are all well known diseases that viruses cause. Viruses can be especially dangerous because they can infect all six of the kingdoms. However, the truth is that viruses don’t want to harm you or cause death; they merely want to complete their function and that is to reproduce. And, since viruses can’t reproduce unless they are in a host cell the virus sets out to find a host cell to reproduce in. Sadly, since most viruses are parasites they destroy their host after it has reproduced. When the host is destroyed the process starts all over again. So that is how viruses kill us from the inside. But like I said viruses can also help, scientists have found a way to manipulate the virus and its ability to survive in harsh environments into helping make more good viruses. This is called gene therapy, the old genetic material is removed from the virus and new material is put in; so when the virus reproduces it will make more of the good virus. This has already helped doctors with some medical problems. Bacteria too help us in many ways. There help break down molecules, that our body can’t, in our digestive tract, decompose dead vegetation and corpses, cleaning up oil spills and the environment, and they take a part in making a lot of foods. Without bacteria we wouldn’t have cheese, pickles, sour dough bread, yogurt, olives, and much more. These little microorganisms also helped make the environment liveable for us billions of years ago by slowly filling the atmosphere with oxygen. But there are also some bacteria that cause some very nasty things. Tuberculosis, strep throat, and pneumonia are all diseases caused by bacteria. Protists are also helpful and hurtful. Firstly, protists make up most of the world’s ecosystem and without that we wouldn’t be able to survive. On the other hand protists are also responsible for many of the world’s most vicious diseases, such as malaria.

This is a picture of the protist that causes malaria. [] Kailey: that was really really really really really really really really really really great. you are such a good writer. =SoHyeon=

How do viruses, bacteria and protsts impact our lives in both positive and negative ways? Viruses, bacteria and protists impact on us in positive way for example : bacteria could make our foods like cheese. Bacteria also could break down foods for us. On the other hand it could also give us some negative effect. They could be negative to us or to environment because viruses could harm the host. Bacteria could harm the environment and human by giving us disease and make the food to go bad. Protsts could cause disease like malaria on humans but people who lives in Shanghai isn't a real concern because malaria is caused in hot places.

Kailey: I am going to comment on my own essential question answere because i am the last person and nobody else will, so here goes: KAILEY THAT ROCKED I LOVE IT YOUR ANSWERE IS AWSOME!!!!!!!:)

=Alex= Viruses, bacteria, and protists. They are all small, but they are very powerful. Especially when there are a lot of them. They can all cause disease. Face it, you can die from one of these small organisms. The Influenza of 1918 (virus) killed more people than in World War 1. Some of you may know this as the Spanish Flu. There was once a bacterial disease that at one stage caused swelling of the lymph nodes. At this stage, the mortality rate was almost 100%. It’s the Black Plague, and yes, it's a bacterium Yersinia pestis, not a virus. Protozoa can also cause harm. Over 30,000 people die from this protozoan disease every day. Any guesses? It’s Malaria. On the brighter side, viruses are now used in gene therapy, where scientists take the bad genetic material out of viruses, and put in good genetic material. Kind of like making a bad guy a good guy by switching their brain. Something like that. Well for bacteria, you know cheese? Yeh, bacteria made that, as well as yogurt, pickles, and your average “molded” up stuff that's edible. Protists are like bacteria and fungi in one sense; in the sewage treatment sense. It can help clean up wastes, while providing oxygen for life on the planet. Around half of all the oxygen is from protists. Protists are also used to thicken some ice cream. Now that's some food for thought. A image of Toxoplasmosis, a protozoa caused disease. Not so dangerous (usually), but very abundant

=Lukas= As already often said, bacteria, viruses and protist can both have a negative and positive impact of our life. There are certain ways that a protist can be helpful. Algae are green because they contain chloroplasts that help them photosynthesize. This mean that they produce oxygen, what we need to live. Viruses are mostly harmful! If a virus enters a host cell, it begins to reproduce inside the host. Then in it will burst out of the host and infect other cells. Since cells are the basic unit of all organisms, a virus can affect the organism’s health just by entering one of the organism’s cell. Bacteria on the other hand, are mostly helpful! They help us and our environment. For example they protects us against other harmful bacteria and produce some of the vitamins our body needs. Unfortunately, there are bacteria that cause harm to our body like strep throat and food poisoning. Protists that are animal-like can be helpful and harmful at the same time. There are some parasitic protists can cause harm to some organisms. For example African sleeping sicknes, also known as African trypanosomiasis, is caused by another sporozoan, //Trypanosoma//. //Trypanosoma// is transmitted through the African tsetse fly. This organism causes high fever and swollen lymph nodes. Viruses, bacteria, and protists can make a huge impact in our lives in many different ways ...whether its negative or positive.
