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).

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

These microbes are Archaeans that cannot grow below 80 degrees C and prefer neutral pH ranges.

Different strains of bacteria can be classified based on used of animal blood serum with antibodies (antisera) that recognize and react with bacterial cell surface molecules.  One example is blood typing. This is known as:  

These prokarytoic phototrophic microbes have helped shape the earth’s atmosphere. They contain chlorophyll a for photosynthesis, gas inclusions, produce oxygen gas, and have heterocysts for nitrogen fixation.

All are true about vectors except:

These Archaeans need a very high salt environment to survive and can spoil salted foods like fish & sausages

Match the protozoan to the disease or symptoms it causes.

These phototrophic bacteria live in anaerobic mud at the bottoms of lakes and ponds that are rich in hydrogen sulfide. They have bacteriochlorophylls and are anaerobic (do not use oxygen gas) and anoxygenic (do not produce oxygen gas).

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:
