protein
a pure substance
The answer is likely supposed to be "an element", but ANY chemical substance contains only one type of particle, whether it is an element (atoms) or a compound (molecules). It is only combinations of elements or compounds (alloys, solutions, mixtures) that contains multiple types of particles.
A prion is a small infectious particle that contains a misfolded protein. These contain no DNA or RNA. These cause Creutzfeldt-Jakob disease, Scrapie in sheep and Kuru. These are deadly and progressive nerve wasting diseases.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.These two are the smallest infectious particles. They are not called microorganisms because they are not alive any more than viruses are.
Matter that contains only one type of particle is known as a pure substance. For example, an element like hydrogen consists solely of hydrogen atoms, while a compound like water is made up only of water molecules. In contrast, mixtures contain two or more different types of particles. Thus, pure substances are the only kind of matter that can contain only one type of particle.
Yes, bacteriophages are viruses that specifically infect bacteria. They target bacterial cells by injecting their genetic material into the bacterial cell and using the host's cellular machinery to replicate.
Prion.

A single atom of hydrogen-1 is the smallest particle of hydrogen. A hydrogen-1 atom contains only one proton and one electron, and is the simplest atom.
Yes, a particle can consist of only a single atom.

Blue crabs may have a prion disorder although brief research doesn't yield any information regarding the existence of one. Prion issues can be present in a species and only be transmissible intraspecies.
An infectious agent consisting of a protein is a prion. This is a mis-folded 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.
Yes, bacteriophages are viruses that specifically infect bacteria. They target bacterial cells by injecting their genetic material into the bacterial cell and using the host's cellular machinery to replicate.
A proton is a positively charged subatomic particle. It generally contains 1 up and 2 down quarks. The number of protons in an atom determines its atomic number.
A pure substance has only one kind of particle. Sulfur is an example of a pure substance.
