Which three of the following entities are acellular?.
arsen [322]

Answer:

Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.

While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood. 

Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.

Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.

Of the 8 characteristies of life (RAREHOCO), which characteristics do
ElenaW [278]

Virus are living because they:

Reproduce, have Genetic Material (Nucleic Acids) and Adapt

.

Explanation:

Virus have genes or genetic material which are layered in a capsid or protein coat and sometimes a lipid bilayer.

It is not made up of cells yet can be considered a living organism because of the genetic material RNA or DNA in it.

The infect the host and take over host replication machinery and replicates itself. Although it is not able to replicate outside the living body.

They adapt to the host's body environment as many adaptation are present in it as capsid layer which protects its genetic material from getting degrade till the time it reaches nucleus of the cell.

There are 7 point criteria for an organism to be living, virus fulfils some of it except having made up of cells and having cellular organization.
