How do viruses, bacteria and protists impact our lives in both positive and negative ways? toc** =Keshav= yet another woot post. Heheheh. How do bacteria, protists, and viruses both affect our lives in both positive and negitive ways? The answers are, of course, endless; though, as I don't want to put you to sleep, I will only be focusing on some of the main points. For example, bacteria help us because them to help mke fod. They are also used to make insulin, and to clean up the environment. However, they harm us by making us sick, and spoiling our food. Viruses, on the other hand, weren't good for anything until recentley. Now, they help make vaccines (as do bacteria), and are being used in gene therepy. When the harm us, uh oh, you better watch out. Whaen a bacteria makes you sick you can kill it with an antibiotic (most of the time); but when a virus makes you sick, you can't do anything except cure the symptoms, rest and stuff, and wait it out. Viruses are nonliving, which means that they can't be killed. Oh, and they can infect all kingdoms, where as bacteria and protozoans can't. Protozoans, not god for much except creating oxygen and being eaten (some); but they ca make you very sick. sure, they can be killed, but hey, prevention is better than cure!

 * Viruses **


 * Well viruses are usually negative because:**
 * 1.** **They are nonliving so you can’t get rid of them (kill them).**
 * 2.** **They cause really painful and bad diseases.**
 * 3.** **They are so small that you can’t see them with out a microscope.**
 * 4.** **You never know when they will attack.**
 * 5.** [[image:file:///C:%5CDOCUME%7E1%5Cuser%5CLOCALS%7E1%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_image002.jpg width="175" height="175" caption="http://www.mywebgarden.com/tulips/Tulip_Index_images/Rembrandt_Tulip_II.jpg"]] They attack not only humans but animals to.


 * Sometimes they can be positive:**
 * 1.** **They are helpful because they can cure diseases by gene therapy.**
 * 2.** **They can cause plants change color ex. Rembrandt tulip.**


 * Bacteria **


 * Bacteria are negative because:**
 * 1.** **Diseases.**
 * 2.** **Food can rot because of them.**

WooHea: I think the viruses are not attacking us, but they are just doing what they are supposed to do.(growing, reproducing) They might damge, or even kill our cells, but their job is not to attack the cells. And bacterias can also infect archaebacteria, eubacteria, protists, fungi. Animals and plants are just two of them. I like how you divided the sections.( good, bad, bacterias, virus)
 * They are positive because:**
 * 1.** **About 20% of Earth’s deposits of natural gas were produced by bacteria that lived millions of years ago.**
 * 2.** **Cheese, apple cider, yogurt, sour milk, sour dough bread, kimchi, contains bacteria.**
 * 3.** **They are decomposers.**
 * 4.** **They help with cleaning up oil and fuel spills.**
 * 5.** **There are big amounts of bacteria in medicine.**

Haley: I like how you told how they can be positive and negative in a precise way that is easy to follow.

Michael: I liked how you organized it so it is easy to follow. Also, humans are animals. Keshav: Lists are always good for things like this. Informative post. Robert: You didn't put how protists impact our lives in positive ways and negative ways. =Yiannis= Viruses are negative because they can attack all six kingdoms. They come in two different types of attacks the hidden and the active. Active viruses are viruses that as soon as they get into the cell they start making copies of themselves. Now hidden viruses are dangerous, they hide in the cell until they are triggered. You can't even know if they are there until after they are triggered. They are small and hard to detect. Another way of not knowing if or when a virus will attack you. The most dangerous thing about viruses are the diseases that they cause and how you can't stop them. You can't stop them because they aren't alive, however you can make it more livable.

Viruses are becoming more positive. One way is they are taking the outer coat after the genetic material is gone, and fill the inside with anti-biotics. After you do all of that, you can send the helpful virus into a spot of infection, and destroy it.

Bacteria are negative because they cause diseases. Although you can use anti-biotics to destroy the bacteria, since it is living. They are also negative because if the conditions don't prevent it, it can spoil your food. For example, if you can refrigerate some food or freeze it to prevent from spoiling. You can also salt or smoke meat to keep it from spoiling. Without these the bacteria will get at the food, in order to feed itself.

Bacteria are positive because they help digest food in the stomach. The ancient ancestors of modern bacteria made it possible for more complex beings to live by creating more oxygen on earth. Bacteria also love to eat oil. This means that they will eat up excess oil, or even oil from oil spills. These ways make the world more livable for humans, and other species.

WooHea: Bacterias could spoil the foods, but they could also grow in milk and produce many delicious foods. I think you fogot to include it. I agree with you that the most dangerous thing about viruse is that we can't kill them because they are not alive.

Haley: I like how you gave examples on how to stop food from spoiling. Maybe you could explain how refrigeration, etc. stop food from spoiling.

Michael: I liked how you had one paragraph for positive and negative.

Keshav: I like how you explained both active and hidden viruses.

Robert: You didn't put how protists impact our lives in positive ways and negative ways.

=Michael= Essential Question #2: How do viruses, bacteria and protists impact our lives in both positive and negative ways? Viruses are mostly negative. As I said in EQ1, they are not alive and can’t be killed. Also they are so small; you can’t see it and can’t see it with a microscope at our schools. Viruses can attack all six kingdoms and cause harm to them. They are the ones responsible for a lot of diseases such as HIV. Hidden viruses are hidden and you don’t know where they are, what disease it will cause, and lastly, when they will strike. Bacteria are a different thing. Without bacteria, we won’t be here! Some archaebacteria that uses photosynthesis added O2 to the earth’s atmosphere 3.5 billion years ago. Another thing is that, without bacteria, we won’t get all the nutrients we need! Bacteria in your intestine are very important. They break down molecules that your body can’t. Lastly, bacteria are used to clean up gas spills and oil spills. Hetetrophs that eat oil and gas are used so that the bacteria can eat it all up and then it will be gone. But every body knows that bacteria are bad too. Bacteria are responsible for wiping out 1/3 of the population of medieval Europe, know as the bubonic plague. Another reason is why your meat can spoil. Bacteria grows on it and starts to eat it and soon it will smell and you might not want to eat it.

this picture shows the bubonic plague in the medieval ages.

=WooHea= Both bacteria and viruses can be helpful and harmful. What is a virus? A virus is a small, nonliving particle that invades and then reproduces inside a living cell. The living cells that a virus lives on or in is called the hosts. But one thing we have to know is that the job of a virus is not destroying, or killing the host. They just need a living thing to grow and reproduce. But sometimes they damage or kill the host when they reproduce. For example, Tobacco mosaic viruses infect tobacco plants, and this is one of the bad impacts on the plants, and to us. Because viruses are all around us, we should have to think of a way to KILL the viruses. Unfortunately, viruses are not alive, so we kill or do anything about them. Good news is that the only jobs for viruses is to grow, reproduce and to leave the cell( host) when they are done, scientists think of a way to make a good use of it. And finally, scientist concluded that we could take the genetic materials from the viruses, and put important genetic material in it. Then, the viruses would go around and spread the genetic material that we put in them. So the viruses are like “ messenger service. ” What is a parasite? Parasites are the organisms that live on or in a host and cause harm to the cells. Because viruses can infect the organisms of all six kingdoms, parasites can infect, too. What is a bacterium? The bacteria are the organisms that are so small, and can not see. The good impact for our lives are fuel, food production, environmental recycling and cleanup, and the production of medicines. We humans depend on bacterias a lot! For example, we eat pickles, buttermilk, yogurt, and cheese which are all produced by the bacterias.(Well, they do not produce it, but they live in milk and chage it to those things.) Baterias act as decomposers, too. They break down large chemicals in dead organisms into small chemicals so that other living things can reuse the dead organisms. Of course the bacterias have harmful impacts too! They can cause many different diseases such as lyme diseases, staphylococcus aureus. They can also spoil the foods, and if we eat it, it can make us very sick. []

This is the picture of tomatoes that are infected by tobacco mosaic viruses!!! Yikes!

Ivory: I like how you explained what some words meant, like parasite and virus. Robert: You didn't put how protists impact our lives in positive ways and negative ways.

=Haley=

Bacteria are helpful because they break down food in our intestinal tract, they help make many types of food, they change nitrogen gas into nitrogen compounds that plants need to grow, and much more. But bacteria are bad because they spoil food, and they can get us sick. And even though we have antibiotics that kill the bacteria, the bacteria could soon get immune to them, which could create a string of bacteria that we cannot cure with antibiotics. For young children though, bacteria and viruses play an important roll in building up their immune system so they don't die from a common cold. Viruses, on the other hand, are also good and bad. Because all they do is put their genetic materials inside other cells, scientists have created gene therapy. Gene therapy is when drugs are put inside a virus and then the virus is sent to a place in your body which is sick. For example; it could be sent to a place in your body that is infected with cancer. This is better than just giving the patient the drugs because you can measure the amount the person needs and then send the correct amount. When you just give a person the drugs, they could cause serious side effects. Viruses are bad because they make you sick and you cannot kill them off, since they are non-living. Viruses can also infect everything living, although each virus only infects/affects a certain type of organism.

I chose this picture because bacteria are in your intestines. Ivory: I think it was really good how you included that young children need viruses and bacteria to improve their immune systems. Robert: You didn't put how protists impact our lives in positive ways and negative ways.

=Isaac=

Keshav: ??????????? Robert: What happened? =Alison= Viruses and bacteria can both be harmful and helpful in many ways.

Viruses are everywhere! Viruses are non-living things so they do not respond to their surroundings, which means they cannot be killed. When they enter our bodies, we won't be able to kill them. And they will go on and harm other cells, making us sick or feel ill. Sometimes, viruses can be very violent. The virus will spread the to many places and contaminate more of the six kingdoms. They can be very scary at times! Bacteria can be both harmful and helpful too. Bacteria will spoil our food, and making them rot. They can also cause serious illness. The good thing is that bacteria can be very helpful to us too. They are in you're intestines, helping you to break down the food that you cannot break down. Bacteria can also help make food that we like: yogurt and cheese. It is bacteria that made them so delicious. Bacteria can also help clean up the earth's environment, as they are decomposers. They also help clean up oil spills. [|www.qsrmagazine.com] I think my picture relates to the topic because yogurt would not be yummy without bacteria. Robert: Um... Nice yogurt ice cream picture, I guess? Robert: You didn't put how protists impact our lives in positive ways and negative ways. Back to Top
