How are viroids and prions the same?
Both Viroids and Prions have nucleic acid, but Viroids have no outer protein coat.
What are 2 non-living pathogens?
Viruses and prions are examples of non-living pathogens. Viruses require host cells to replicate, while prions are misfolded proteins that can cause disease by inducing other proteins to misfold.
Are prions and viroids smaller than a virus?
yes
How are bacteria unlike virusesviroidsor prion?
Bacteria are single-celled prokaryotic organisms that can reproduce independently and have cellular structures, including a cell wall and metabolic machinery. In contrast, viruses, viroids, and prions are acellular entities; viruses require a host cell to replicate, viroids consist of short RNA strands without a protein coat, and prions are misfolded proteins that induce misfolding in normal proteins. Additionally, bacteria can carry out metabolic processes and respond to stimuli, while viruses and prions do not exhibit metabolic activity.
The only known infectious agents that lack genetic material are A. certain viruses. B. prions. C. viroids. D. none of the above D?
The only known infectious agents that lack genetic material are prions. Prions are misfolded proteins that can cause other proteins to misfold and aggregate, leading to neurodegenerative diseases such as Creutzfeldt-Jakob disease.
How are viroids and prions the same?
Both Viroids and Prions have nucleic acid, but Viroids have no outer protein coat.
What kinds of microbes are there?
I) Prions II) Viroids III) Viruses IV) Archaebacteria V) Eubacteria, and VI) The Protists.

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.
Which is the smallest virus infecting human beings?
The human rhinovirus, the virus that causes common colds, is the smallest human-infecting virus, with an average diameter of about 30 nanometers. Other viruses such as smallpox are around 10 times larger, at 300 nanometers.
What are acellular particles?
Acellular particles are basically just particles that aren't made up of cells (aka non-cellular). These include viruses, prions and viroids. Because they aren't made up of cells, they aren't classified as living organisms. They are obviously neither eukaryotic or prokaryotic.

What are viroids and prions?
I have no idea so go ask someone else. The similarities between viroids and prions are that both are acellular pathogens, and do not grow and they differ in the sense that prions do not have nucleic acids while viroids have the nucleic acid,RNA.
What are the types of microorganism?
There are many things considered to microscopic microorganisms. The term organism means that these are alive so viruses, viroids and prions are not part of the group. That leaves bacteria of various sizes and shapes, protozoa and phytoplankton.
What is acellular obligatory parasite?
An acellular obligatory parasite is a type of parasite that lacks cellular structure and relies on a host cell's machinery for survival and reproduction. Examples include viruses, viroids, and prions. These parasites cannot replicate or carry out metabolic functions independent of a host cell.
