A virus is a microorganism that can only replicate itself inside a host. In other words, its a parasite. A little like fungus, viruses can't make their own food, so they try to find something that will give them nourishment. Some viruses have evolved smartly and can survive as they move from host to host. Other viruses are so greedy they suck all the nutrients from their host killing it and themselves. But one thing that scientists have struggled to agree on is whether or not viruses are alive. After all, they can't survive or replicate without a host cell, and due to their rapidly changing genes, scientists have never been able to work out how or when they evolved. Viruses are fairly similar to bacteria. There is a good virus, bad virus and also an ugly virus. The bad virus would make you sick. Viruses are very clever and can attack a large amount of your cells and also kill the good bacteria. A virus can cause many illnesses such as AIDS, Small pox, Rabies and many more. Viruses spread at a very fast speed and even the slightest cough or a sneeze can spread the virus. There are few types of medicine to beat the virus. Just like the bacteria, the ugly virus is the worst one out of all of the viruses. The ugly virus spreads super fast that it can spread through the whole world. The symptoms of the ugly virus is very horrible and it causes headaches and being sick. The Pandemic flu, also known as the Spanish-flu killed, spread through the world killing a large amount of people. Viruses are very odd: This one attacks bacteria. I think it looks like some kind of space ship! This teeny-tiny structured virus has killed many people; Influenza or the Flu. A tiny sticky ball.... The virus on the bottom left and on the right have been found to cause Cancer. Viruses are really not our friends. Every time we cough or sneeze we have little viruses that are trying to find a new person to get their nutrients from, terrorize their hosts bodies and make them miserable. If these little viruses aren't living...it makes you wonder what they are? Aliens from another planet? How can something so small make you feel so awful!!

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
