A pathogen is a microscopic organism, such as a virus, bacterium, fungus, or parasite, that causes disease in its host. Pathogens can infect humans, animals, plants, and even other microorganisms.
The structure of a virus, with its protein coat and genetic material, allows it to enter host cells, replicate its genetic material, and produce new virus particles. This structure also helps protect the virus from the host's immune system and other environmental factors. Additionally, the compact size and shape of viruses enable them to efficiently infect host cells and spread from one organism to another.
An organism that can provide a source of energy for a virus or another organism is called a host. The host organism can provide resources and nutrients necessary for the growth and reproduction of the virus or another organism that depends on it for survival.
it will cause a disease in the organism
Bacteriophage
Because the living organism has to replicate the DNA that the virus infects the host with. It can't do this if it is a dead organism.
rabies, but that's kind of vise-versa don't you think?
A virus or parasite that lives within an organism lacking a nucleus could infect a prokaryotic cell, such as a bacterium. In this case, the virus or parasite would utilize the host's cellular machinery to replicate and survive without the presence of a nucleus.
No, a virus cannot catch a virus and become ill. A virus is a shell of protein containing DNA. A virus works by getting into a cell and "reprogramming it" to multiply and start to take of the organism. A virus cannot infect another virus because viruses are not cells themselves.
Bacteria are unicellular. The cells of the organism they infect are, quite often, part of a multicellular organism.
The infect your computer by being undetected by your anti virus and posing as a harmless file.
Viruses only infect living organisms and since they are not alive, they can not infect other viruses. The question is interesting though.
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
Liver flukes are caused by parasitic flatworms known as trematodes. The most common types that infect the liver include Fasciola hepatica and Clonorchis sinensis. These parasites typically infect the liver and bile ducts of mammals, including humans, and can lead to serious health problems.
no
A virus cannot divide by itself because it is not a living organism. Instead, it hijacks a host cell's machinery to replicate its genetic material and produce new virus particles. The virus then assembles these new particles and releases them to infect other cells.
No bacteria is huge compared to a virus
