Virology is the study of viruses and their evolution, structure, classification. It also is complexes of nuclies acids and proteins that help all living cells.
Bacteria are able to reproduce on their own while viruses need a host to "hijack" so they can reproduce. Bacteria have metabolisms, catabolic and anabolic biochemical reactions going on in their cells all the time. Viruses do not. Bacteria can grow in size to a certain extent while viruses do not change in this regard. The definition of living things classify bacteria as a living thing, while viruses are not.
A virologist studies viruses and their potential uses.
Biologists consider dormant virions to be non-living because they must obtain a host to function and replicate themselves. However, active viruses are considered to be living, by most scientists.
Viruses in general are somewhere on the border of "living" and "non-living" - they have some characteristics of living beings (notably, they can reproduce), but they lack others (such as a metabolism).
Viruses and bacteria are both microscopic organisms that can cause infections in living organisms. They are different from each other in terms of structure and how they reproduce, but they can both cause diseases in humans, animals, and plants.
Viruses are neither prokaryotes nor eukaryotes as they are not living cells and do not have cell structure. They are parasites of living cells.
Bacteria and viruses are small and can only be seen through a microscope. The small living things are microorganisms or microbes. Some people do not think viruses are living things because they are acellular particles. They consider them to be an organic structure that interacts with living organisms.
A person who studies viruses is called a virologist. Virologists study the structure, evolution, and behavior of viruses to understand how they infect living organisms and cause diseases.
Viruses lack the cellular structure and independent metabolism typically found in living organisms. They can only replicate inside a host cell by hijacking the cell's machinery. This unique mode of reproduction blurs the line between living and non-living entities, making viruses challenging to classify definitively.
Viruses do contain genetic material and a protein coat, but they lack the cellular structure found in living organisms. They are considered to be organized structures, but they are not considered to be living organisms due to their dependency on host cells for replication.
Viruses are considered non-living because they lack cellular structure and cannot carry out metabolic processes independently; they require a host cell to replicate and reproduce. Additionally, viruses do not exhibit growth or respond to stimuli in the way living organisms do, as they remain inert outside of a host.
viruses are not considered to be living organisms as they lack the cellular structure and cannot carry out cellular functions on their own. They can only replicate by hijacking the machinery of living cells. Therefore, viruses do not challenge the concept that all living things are made of cells.
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.
Viruses do not fall into traditional classifications of living organisms as they lack cellular structure and cannot carry out metabolic processes on their own. They are considered as biological entities that straddle the line between living and non-living.

because they gain the 7 characteristics only when they enter a body and they don't have a proper cell structure.
