what is the diffrence between virus and bacteria?

Answer 1

A virus is about 10X smaller than a bacteria. A virus is about 100 nm in size while the bacteria about 1000 nm and greater in size.

A virus needs a host to survive while a bacteria does not.

Answer 2

Bacteria are procaryotes meaning that they don't have a proper nucleus. Their DNA is in a simple circular structure rather than in the form of chromosomes. Bacteria have cell walls and cytoplasm.

Viruses have a relatively simple structure. For example, the influenza virus has a lipid (fatty) envelope that surrounds the protein shell (capsid), which encloses coiled genetic material (RNA). Projecting from this envelope are two kinds of protein spikes, hemagglutinin and neuraminidase. These proteins act as antigens, eliciting an immune response in the organism that the virus invades. Influenza viruses exhibit the unique quality of periodically mutating these protein spikes. Because the viruses continually change, they can cause repeated waves of infection, even among people previously infected.

Answer 3

Bacteria are microorganism with cell membrane,Nuclear material,Protoplasm,some time bacteria also contain photosynthetic material for photosynthesis.They can multiply their number through conjugation or fission.They donot need a host for multiplication.
On the other hand virus only contain protein coat ,tail and single stranded RNA.It is inactive outside the body of host.It cannot multply indepndently.It first of all attached to the host DNA and then multiply with it.

Answer 4

a pandemic is an obligate intracellular parasite incapable of reproducing without host cellular dna/rna or replicative mechanisms this is a small element of the skill with the help of which they mutate so without postpone and why there are so few cures for thus few viruses. Viruses additionally do no longer metabolize fuels and are unable to irritability(the skill to respond to their ecosystem) that are a pair of the justifications they don't seem to be categorized as residing organisms. micro organism are single celled organisms & antibiotics artwork with the help of numerous distinctive mechanisms. some abx artwork with the help of destabilizing cellular partitions/membrances & some intervene with their dna/rna replication, some are bacteriostatis, ugh, in any case there are a ton of the thank you to kill the little buggers. The physique has distinctive mechanisms to combat viruses and micro organism which includes, yet no longer constrained to, interferon and the supplement cascade, respectively. this is this variety of long subject save in mind that the appropriate way so you might realize it could be to take a microbiology type.

Answer 5

bacteria are particular micro organisms which can multiply all by themselves whereas virus first need to enter another host cell and only then can they multiply.outside a host cell viruses cant be called living organisms.

Answer 6

Bacteria are considered living organisms. Viruses are considered non-living chemicals.
