How do viroids and prions compare with viruses?
Viroids are small infectious agents consisting of a short, single-stranded RNA molecule, while prions are misfolded proteins without nucleic acid. In contrast, viruses are composed of genetic material (DNA or RNA) surrounded by a protein coat. Viroids and prions lack the ability to replicate independently, unlike viruses which require a host cell for replication.
Is salmonella protozoa virus bacteria or fungi?
Salmonella is a type of bacteria, specifically a genus of rod-shaped, gram-negative bacteria. It is known to cause foodborne illnesses in humans and animals, typically through contaminated food or water. Unlike protozoa, viruses, or fungi, Salmonella bacteria can multiply and thrive in various environments, including the intestines of animals.
Is a bacterial cell unicellular?
unicellular, however sometimes they are associated in groups or long strings.
Do viruses have a cell membrane?
No, viruses do not have a cell membrane. They are considered acellular entities that consist of genetic material (DNA or RNA) encapsulated in a protein coat called a capsid. Viruses require a host cell to replicate and do not have the ability to carry out cellular functions on their own.
Can you give the same bacterial infection back to the person who gave it to you?
It is possible for a person to get reinfected with the same bacterial strain if they come into contact with the person who initially infected them, especially if the person is still carrying the bacteria. Practice good hygiene and take necessary precautions to prevent reinfection.

Viroids and prions lack the ability to replicate independently, unlike viruses which require a host cell for replication.
What basic structure do viruses share?
Unlike prions and viroids, viruses consist of two or three parts: all viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. Viroids do not have a protein coat and prions contain no RNA or DNA. In short, just say that all viruses have a protein coat and either DNA or RNA.
How do viruses reproduce compared to bacteria?
Viruses replicate inside body cells, using the host cell to do the work and provide the materials for reproduction. Bacteria reproduce outside body cells and, since, unlike viruses, they are living organisms, bacteria are able to do the work and production of new bacteria without a need for a host.A description of the 'Lytic Cycle', the process that some types of viruses follow in reproduction, is given in the related questions below for more detail of the process of reproduction of some viruses inside body cells.

Why bacteria are considering living?
because they do have the 7 characteristics of life which are movement, respiration, sensitivity(irritability), growth, reproduction, excretion and nutrition. they also have a proper cell structure unlike viruses.
How are real viruses unlike computer viruses?

What is viriod?
A viroid is a small, circular RNA molecule that infects plants and can cause diseases. Unlike viruses, viroids do not have a protein coat and rely on the host plant's cellular machinery for replication. They can disrupt the normal functioning of plants and impair their growth and development.
Is the virus common cold aerobic or anaerobic?
Viruses, like the common cold virus, are not categorized in that way as bacteria are. Viruses are neither. Since they are non-living organisms (unlike bacteria that are living), they have no oxygen requirements and can be "active" with or without it. Their hosts' cells, that they hijack to create new viruses, do need oxygen, however, so it is necessary for the cells so they can reproduce the virus particles for viral reproduction, but not necessary for each virus particle itself.
How are viruses unlike organisms?
Unlike organisms, viruses are not cellular, nor do they have ribosomes or any other organelles for protein production, energy generation, etc. They cannot capture or store free energy but can only use energy derived from their host. Also, viruses can only reproduce via the host and not on their own.
How is a lysogenic virus different from a lytic virus?
Unlike lytic viruses, lysogenic viruses do NOT lyse the host cell right away where as lytic cells do.
Is a bacterial cell unicellular?
unicellular, however sometimes they are associated in groups or long strings.
