The human rhinovirus, the virus that causes common colds, is the smallest human-infecting virus, with an average diameter of about 30 nanometers. Other viruses such as smallpox are around 10 times larger, at 300 nanometers.
False. Prions and viroids are the smallest infectious agents. Prions are infectious protein particles, and viroids are infectious strands of RNA. Viroids differ from viruses in that they are ONLY a strand of RNA. Viruses have a protein coat protecting the nucleic acid molecule and some even have a lipid layer over that.
Virus
polio virus
bacteriophage
Human beings and mosquitoes are the only known natural hosts for dengue viruses. Some animals, such as mice, can be infected with Dengue virus in a laboratory setting under very special conditions but as far as I know this has not been done with dogs and there has never been a documented case of Dengue virus infecting dogs in the wild.

A virus which lack envelopes only the have a capsid(protien coat) made up of capsomers their name is PLUS STRAND because they act directly as a mRNA after infecting the host cell.they infect plants and bacteria causing POLIO and COLD in human beings e.g polio viruses and rhino viruses
infecting living cells
a virus capable of infecting other species
It has to fit the shape of the cell that it is infecting.
Infectious bursal disease virus (IBDV) is infecting Antarctic emperor penguins.
Because it act like a disease, infecting things and destroying them. And adapting to it's enviornment.
Yes. Because Obelisk the Tormentor is only protected from card effects that do not target, Tribe-Infecting Virus will be able to destroy Obelisk the Tormentor via its effect.
