What are the simplest infectious biological systems?
Viroids
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.
How are viroids and prions the same?
Both Viroids and Prions have nucleic acid, but Viroids have no outer protein coat.
Can viroids affect humans?
no
What is an RNA particle that causes disease?
A plant pathologist discovered an infectious RNA particle smaller than a virus that causes diseases in plants. He called it a viroid. Millions each year are lost by these viroids. These contain only RNA.
What are the simplest infectious biological systems?
Viroids
Infectious naked strands of RNA are called?
Viroids
What type of RNA is infectious in plants but not technically a virus?
Viroids.
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.

How are viroids and prions the same?
Both Viroids and Prions have nucleic acid, but Viroids have no outer protein coat.
How is the target host of a viroid-caused infectious disease different than the host of other pathogens?
Viroids are a non living pathon that effects primarily plant cells
Describe the 4 kingdoms that comprise the domain prokarya?
The domain Prokarya consists of the kingdoms Bacteria, Archaea, Viruses, and viroids. Bacteria and Archaea are single-celled organisms with prokaryotic cells, while viruses and viroids are acellular infectious particles. Bacteria are diverse and found in various environments, while Archaea are often extremophiles. Viruses and viroids are not considered living organisms and require a host for replication.
Why is so little known about viroids?
Why is so little known about viroids
Can viroids affect humans?
no
What the meaning of organs?
An organism is any living thing (i.e. it fits all the criteria required for something to be considered "living"). Examples include bacteria, plants, fungi, protists, and animals. Be careful though, because viruses and certain other infectious agents, like prions and viroids, are not officially considered living things by all scientists.
Which of these is an infectious agent composed of a simple strand of RNA with no protein component viroid vector prion virus?
An infectious agent consisting of a protein is a prion. This is a misfolded protein. It can cause several central nervous system diseases including Creutzfeldt-Jakob Disease, Fatal Familial Insomnia and Kuru in humans, Spongiform Encephalopathy in cows, mink, and cats plus Scrapie in sheep.A VIROID consists only of a minuscule circular RNA molecule, lacking the protein coat of a virus. Viroids appear to be transmitted mechanically from one cell to another through cellular debris. They infect only plants. Viroids are common plant pathogens which cause severe economic problems.A vector is something that carries something else. Like the bacteria on our hands or the ones on the feet of flies.A virus is much more complicated than the viroid or prion and has DNA or RNA (not both) as their genetic material with a protein coat surrounding them.
