A colorless, highly pungent solution of hydrogen chloride (HCl) in water, when it reacts with an organic base it forms a hydrochloride salt.
Bacteria are intercellular organisms (i.e. they live in-between cells); whereas viruses are intracellular organisms (they infiltrate the host cell and live inside the cell). They change the host cell's genetic material from its normal function to producing the virus itself.
Similarities: 1.Both are very small (measured in nanometers) 2.Both can cause disease, or are pathogens. Although some bacteria do not cause disease. Differences: 1.Ba â¦ cteria are present everywhere, including the human body. 2.Viruses need a host cell in order to live.They cannot replicate without a host cell.imilarities: 1.Both are very small (measured in nanometers) 2.Both can cause disease, or are pathogens.
