Viruses attack animals, plants, fungi, protists,
and bacteria. Some viruses can infect only
specific kinds of cells. For instance, many
viruses, such as the potato leaf-roll virus, are limited
to one host species or to one type of tissue
within that species. A few viruses affect a broad
range of hosts. An example of this is the rabies
virus. Rabies can infect humans and many other
animal hosts.

How are computer viruses similar to and different from biological viruses?
Both types:are spread by contact with a contaminated sourcecan be blocked with defensescan be modified and weaponisedcan go away after a time if certain measures are takencan kill whatever they infectcan change over timecan be costlyDifferences:computer viruses only work in a computer hostbiological viruses only work in a biological hostbiological viruses can spontaneously mutatecomputer viruses are createdbiological viruses are far more complex
What are the features of Viruses?
1. Viruses are a cellular, non-cytoplasmic infectious agents. 2. They are smaller than bacteria, and this can pass through bacteriological filter. 3. Viruses are transmissible from disease to healthy organisms. 4.All viruses are obligate parasites and can multiply only within the living host cells. 5.Viruses contain only a single type of nucleic acid either DNA or RNA. 6. Viruses are host specific that they infect only a single species and definite cells of the host organisms. 7. Viruses are effective in very small doses. They are highly resistant to germicides and extremes of physical conditions.
Can you show me a Venn diagram of bacteria vs viruses?
hello everyone
What particles reproduce that are made up of nucleic acids proteins and sometimes lipids only infecting living cells?
viruses
What organism that can reproduce only inside a host cell?
viruses can only reproduce in living cells by injecting their own dna into the nucleus
What organisms do aids infect usually?
HIV infects only humans. There are similar viruses that affect other species.
Can viruses can only cause disease?
Viruses can affect animals, and some viruses can affect plants.
Are most viruses species specific?
Yes, the majority of viruses are very species specific. There are exceptions however, such as rabies. Most viruses will not survive for long beyond their host tissue environment.
Why only anopheles cause malaria?
That is a very good question. Equally difficult to answer correctly. You do not know why so many viruses can affect only particular species. There are many species of malaria, which can affect particular species only. For the same reason, malaria can be transmitted by anopheles mosquito only. You can say that that particular mosquito has got particular receptors.
Can viruses be controlled by antibiotics or a vaccine?
Typically only the Flu Virus
Do plant viruses only infect plant species that have RNA?
snow leopards
What is the weakest virus?
There is no definitive answer to this question as viruses vary in their ability to cause harm. However, some examples of relatively weaker viruses include the common cold (rhinovirus) and mild flu strains. These viruses typically cause mild respiratory symptoms and do not result in severe illness or complications for most people.
Why don't antibiotics cure colds?
Antibiotics only affect bacteria and colds are caused by viruses.
Can viruses only cause disease in humans?
Viruses can affect animals, and some viruses can affect plants.
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
Why would antibiotics not help if you had a flu?
Influenza is a viral disease and antibiotics do not affect viruses, only bacteria.
Can humans affect extinction?
Absolutely ! The human race is the only animal species on the planet that has hunted other species to extinction.
