Bacteria are not classified by the number of chromosomes, or the type of mitochondria.
Based on host specificity: viruses can be classified as either specific to a single host species or able to infect a range of hosts. According to the type of nucleic acid they contain: viruses can have DNA or RNA genomes. By their shape: viruses can be labeled as either helical, icosahedral, or complex. According to their mode of transmission: viruses can be classified as either airborne, foodborne, or bloodborne.
Yes, viruses are classified below the cellular level as they are not considered living organisms. They are composed of genetic material (either DNA or RNA) encased in a protein coat and require a host cell to replicate. Unlike cells, viruses lack the machinery necessary for metabolism and reproduction on their own, which is why they are categorized as acellular entities.
Viruses are often classified as nonliving because they lack the essential characteristics of life, such as cellular structure, metabolism, and the ability to reproduce independently. They cannot carry out metabolic processes on their own and require a host cell to replicate and propagate. Additionally, viruses do not respond to stimuli or maintain homeostasis, further supporting their classification as nonliving entities.
They do not reproduce asexually or sexually. Viruses need a host like a cell in order to reproduce. In the dormant state, they are virions, and considered to be nonliving. However, in their active state, as viruses, they are considered to be living organisms.
Viruses are not classified into any of the kingdoms because they cannot live outside of a host cell (they depend on the host cell's DNA to reproduce and undergo metabolic reactions within it).
Viruses are not an organism at all. They are not alive.
Certain poos
It depends on what you mean. If you mean types of viruses, there are:Virii,Trojans,and worms.
Chicken pox is classified as a virus and viruses are not living things, so they are not classified as cells.

viruses, bacteria, algae, fungi, and protozoa
because they are not yet clearly classified
Viruses are classified under the domain of "Riboviria," which includes viruses with RNA genomes. Viruses are not considered to be living organisms because they cannot replicate or carry out metabolic processes on their own and require a host cell to reproduce.
Viruses are very different from the most microorganisms and they are classified as microbes.

Viruses can be classified on which nuclear acid they possess:DNARNAViruses can be classified on the type of protein jacket they employ:a protein jacket unique to their own productiona part of the cell wall of their host cellViruses can be classified on the way they function inside their host cell:free floatingencrypting (these are the really annoying ones)
