most viruses are to small to be seen right through a microscope.Viroses effect any sort of organisms like animals and plants etc. Nutrient cycles depending on the organisms such as the fixation of ...Which allows them to block the virus replication through a form of RNA.
Bacteriophage
it will cause a disease in the organism
The capsid of the cell helps the virus to infect host cells as well as multiply quickly.
host
File Viruses infect applications. These viruses usually infect COM and/or EXE programs, though some can infect any program for which execution or interpretation is requested, such as SYS, OVL, OBJ, PRG, MNU and BAT files. System Sector Viruses infect executable code found in certain system areas on a disk. Macro Virus a program or code segment written in the internal macro language of an application and attached to a document file (such as Word or Excel).
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?
Humans are organisms which can become infected by the influenza virus.
Bacteriophage is the virus that infects bacteria
Pathogens such as a bacterium or a virus can influence the growth rate of the host organism. Virus (not really an organism) can infect a bacterium and integrate their genetic material. This changes the homeostasis of the bacteria, because viral proteins would be start producing by the host. hence the host can not grow as a normal organism after infection.
Bacteria are unicellular. The cells of the organism they infect are, quite often, part of a multicellular organism.
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.
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.
no
Bacteriophage
No bacteria is huge compared to a virus
