A small circular piece of RNA with no capsid that can be infectious and pathogenic in plants. In potatoes it can stunt growth.

This type of persistent viral infection in animals is caused by slow release of the virus from infected cells without cell death. Examples of this type of infection include Hepatitis C and HIV (AIDS).

All are true about the Domain Archaea except:

Different strains of bacteria can be classified based on the use of viruses that infect and destroy specific types of bacterial cells. If the virus infects and destroys that type of bacteria, a plaque will form on a lawn of bacterial cells grown on a petri plate. This is called:

This type of symbiotic relationship occurs when one population is unaffected and the other benefits.  An example are mites in human hair follicles.

Viral spikes that are specific for a particular host cell receptor and allow attachment of the virus determines the:

These traits help distinguish between bacteria and are used to classify them.  They include morphology, size, colony type, endospores, flagella.

Bacteriophage, like phage Lambda, that are capable of a lysogenic replication cycle (lysogeny) are called:

This is a eukaryotic structure used for classification and asexual or asexual reproduction.

A fungus that is a pathogen can produce infections in animals called:
