what are viruses living or nonliving?
92885
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.

Nonliving characteristics include the fact that they are not cells, have no cytoplasm or cellular organelles, and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. 4. Viruses can infect animals, plants, and even other microorganisms.

Viruses are tinier than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells.

Humans, insects, trees, and grass are living things. Nonliving things do not move by themselves, grow, or reproduce. They exist in nature or are made by living things. There are three groups of nonliving things.

1- Both eukaryotes and prokaryotes are living organisms, this is, they can do the three fundamental things needed to consider something "alive": nutrition, relation and reproduction; viruses, on the other hand, can't make those by themselves, they are just a case of proteins with DNA or RNA in the center of case.

Bacteria, Viruses, Protists and Fungi. Fungus: Protists and viruses are not alive while fungi and bacteria are. ... Protists have eukaryotic cells,and can be heterotropic but can be autotropic.

Virus: Viruses are considered as organic structures which interact with living organisms, rather than a living organism. Bacteria: Bacteria are larger, about 1000 nm in size. They are visible under light microscope. Virus: Viruses are smaller, about 20400 nm in size.

Medical Definition of Virus Virus: A microorganism that is smaller than a bacterium that cannot grow or reproduce apart from a living cell. A virus invades living cells and uses their chemical machinery to keep itself alive and to replicate itself. ... Viruses may contain either DNA or RNA as their genetic material.

Cells are the basic units of life. Cells can exist by themselves, like bacteria, or as part of a larger organism, like our cells. Viruses are non-living infectious particles, much smaller than a cell, and need a living host to reproduce. The genetic material of the cell is DNA, a double stranded helix.

Some of the daily life examples of living things around us are human beings, animals, plants and micro organisms. Non-livings things do not exhibit any characteristics of life. They do not grow, respire, need energy, move, reproduce, evolve, or maintain homeostasis. These things are made up of non-living materials.

To put it simple, viruses are non living (or abiotic as you wish to call it) and bacteria are living (or biotic.) There are numerous requirements needed to be considering a living thing and viruses violate a major one, that is the ability to self reproduce.

Nonliving characteristics include the fact that they are not cells, have no cytoplasm or cellular organelles, and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. Viruses can infect animals, plants, and even other microorganisms.

A virus is acellular (has no cell structure) and requires a living host to survive; it causes illness in its host, which causes an immune response. Bacteria are alive, while scientists are not yet sure if viruses are living or nonliving; in general, they are considered to be nonliving.

Answer and Explanation: Viruses are unique organisms. They do not belong to any kingdom due to the fact that they are not made up of living cells.

Viruses have to invade the body of a host organism in order to replicate their particles. Therefore, most viruses are pathogenic. The main difference between bacteria and virus is that bacteria are living cells, reproducing independently and viruses are nonliving particles, requiring a host cell for their replication.

Viruses are not alive, and are not cells. Viruses do not have organelles in general. They are cellular.. they are nucleoproteins.

Viruses can infect only certain species of hosts and only certain cells within that host. Cells that a virus may use to replicate are called permissive.
