According to the research, the correct option is Virus. A parasitic submicroscopic particle that infects and resides in the cells of a biological organism is a(n): Virus.
It refers to an obligatory intracellular parasite, of submicroscopic size, made up of a protein capsid that surrounds the nucleic acid (DNA or RNA) that has the ability to self-replicate when using the cellular machinery.
This structure can be surrounded by the viral envelope (a lipid layer with different proteins) being a potentially pathogenic agent that replicates its genetic material and produces many copies of the original virus.
Therefore, we can conclude that according to the research, the correct option is Virus. A parasitic submicroscopic particle that infects and resides in the cells of a biological organism is a(n): Virus.
