Viruses : A Infectious Agent That Replicates Only Inside The Living Cells Of Other Organisms

for the word. Among many other explanations, being alive is known as being alert and active. Viruses are small infectious agents, which are capable of infecting all kinds of life forms such as animals, plants and microorganisms to name a few. Viruses are very small in size, measuring at 30nm in diameter and lacking internal membranes. Viruses contain a protective, protein coat known as a capsid, which encases nucleic acid (either RNA or DNA). About five thousand viruses have been identified by scientists

of the bacteria into the host cell. Bacteria in general do not have the limitations that viruses do, viruses must have a living host in order to reproduce. Most bacteria are able to grow on non-living surfaces and live intercellularly. Lyme disease is easy to identify because of the bullseye that results from the tick bite infected with Borrelia burgdorfer. Viruses are extremely unique to the microbial world they are the smallest and simplest microbe. Virions are only 20-400nm in size, and they do

No two forms of life are the same, so why are viruses automatically ruled out of this category and deemed simple a product of life by so many scientists? The exhibit many of life's essential characteristics but they are simple overlooked compared to their counterpart bacteria.There are 100,000 of viruses and no two are composed the same way, yes they have their atomic structure, but they all experience variability just like technical life. Viruses are even categorized into genomes based off of

Viruses are infectious organic agents. These Viruses are by far, the smallest organisms to exist, these are smaller than even bacteria, which are much smaller than a human cell. A virion is about one, one hundredth the size of a bacterium. There are about 5000 different known viruses, since their first discovery by Dmitri Invanovsky's discovery in 1892. These viruses are the causes of many illnesses, most commonly, the common cold. Some viruses are especially deadly such as the E.Coli or the Ebola

Are viruses alive? According to the scientists, life is a wonderful, unbelievable discovery. Scientist came up with multiple criteria and requirements in order to determine life. For example, homeostasis, growth and development, reproduction and more. Animals and plants are life, they can maintain their homeostasis, they grow and develop in size, structure and animals also grow in mental complexity. They also need to consume nutrition. So then we use the characteristics and functions of life to determine

they are alive, such as viruses. Viruses are infectious agents(which creates disease) which replicates only inside of living cells of other organisms, it can infect all types of life

Richard Preston’s novel The Hot Zone, was based on a true story about the origins and incidents involving viral hemorrhagic fevers, mainly the Ebola and Marburg viruses. It primarily focuses on the Ebola virus’ first documented outbreak during the 1980s. As you read The Hot Zone, you will notice that it has been divided into four individual segments. The first segment looks into the history of filoviruses, and how AIDS emerged. The novel begins with Charles Monet, an elderly man who travels to Kitum

Other fungi are parasitic and obtain their nutrients from living hosts. 4. Know the classification of fungal diseases (mycoses). 30% of known fungal species produce mycoses, which are fungal diseases of plants, animals, and humans. Classifications of fungi are; Zygomycota, Ascomycota

A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms. A virus spreads upon contact. A virus can lay dormant for years inside a host. A virus can kill. Modern science now uses viruses to deliver gene therapy. Every year pharmaceutical companies take the flu virus and alter it to become our vaccine. A virus changes with each new host. One that mankind has been afflicted There are differing claims as to what constitutes

about viruses, their history and much more. So this is how my interestingly knowledgeable experience started, when I got to interview a virus. Me: How would you like to introduce yourself? Virus: People usually use the word virus for me. I am an infectious agent or parasite. We (the viruses) only replicate when we are present in a living host. We cause infections in all kinds of other living beings, including humans. We are not made up of cells but we need living cells of other organisms for our
