Unlike living things viruses don't have a metabolism, making them obligatory parasites (they can only reproduce if there's a host cell they can hijack). They also aren't a cell, which is considered by many to be the minimal organisational structure of living things.
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
Viruses react to the environment, reproduce (through asexual means), and need energy to survive. They are also capable of passing hereditary information, but that could be included in reproduction.
Most do. The only exceptions are some viruses, and scientists will argue till the cows come home over whether viruses count as living things or not. Some viruses have no DNA. Instead, they store their genetic instructions in RNA. Just one example: the virus that causes AIDS, namely HIV.
Viruses are considered non-living because they are not cells. They do not exhibit some characteristics of life such as reproduction and growth.
Fire is a non-living thing that can be seen as reproducing under certain conditions. When a fire spreads from one area to another by igniting new fuel sources, it can be considered a form of reproduction.
Viruses are microorganisms unable to live on their own, i.e can only live and reproduce in a living cell.Once they infect a new cell,they take over the entire cell machinery and when released,they kill the infected cell.So,viruses reproduce in Living cells. It's been cedrikstorm,garvey02@yahoo.com
1) Viruses do not grow, they are a certain size from the moment they are made. Just a protein coat and a set of genetic instructions. 2) Viruses do not respire they don't turn over energy at all, they hijack living cells which can turn over energy and use them to do their reproduction. 3) Viruses do not excreat waste products- they don't make any so they don't need to. Most living things make some toxic substances which must be got rid off eg carbon dioxide and urea. 4) Viruses cannot reproduce, make more of their own kind without hijacking the apparatus of a living cell.
Viruses are replication parasites that can do nothing until they take over a living cell. Bacteria are living cells.
No, the dsi browser is unable to download ANYTHING even if you want to
Many scientists consider viruses to be non living because each and every living organism must carry out these 7 life processes for it to be considered living: Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion and Nutrition. Viruses do all of these things except reproduction, which they cannot do. Instead, they multiply by using other living organism's cells which has caused a lot of debate over whether that counts as reproduction in the scientific community.
Viruses don't have their own metabolism so they simply can't reproduce without a cell. That's why they are obligatory parasites. Living cells, on the other hand, can channel some of their metabolic energy to reproduce themselves, without having to take over something else's metabolism to do so, like viruses invariably have to.
Viruses are considered non-living because they do not meet all the criteria for life. While they can replicate and evolve, they lack cellular structure, the ability to metabolize nutrients, and cannot reproduce on their own. Viruses depend on host cells to replicate and carry out their life cycle.

These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own. Viruses are not on the borderline of living and nonliving. There are things that are alive like a bug and things that are not alive like a rock. Nothing is in between. Hope this helps:)Before the virus finds a host (viruses are parasitic), they are considered "dead" because they have no living organelles and are not active. However, when they find a host and infects it, they become "alive" and starts using them like a host. Hence, they are considered at the borderline and are neither a living thing or a non living thing.

They are very small and can be considered microscopic. We have to use an electron microscope to see them as they are that small.

Living Things can breath but Nonliving Things cannot. We as Human Beings can move, breath, etc. but a Nonliving Thing like a, stone, can't even do that.
