There is no conscious decision made by a virus in selecting a host. Probability and statistics determine who contracts a virus and who doesn't.
They attach to each other and and
I don't know! Why are you asking me?????
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.
A Nonresident is a computer virus that is not stored on the hard drive of the computer system. Rather, the virus makes a home in an executable file that infects a computer each time it is accessed and run. While Resident viruses do not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution time and transfers control to the host program.
Viruses are cellular parasites.
There are different types of viruses. Some of the prominent ones are Trojan horses , worms, and email viruses. The Trojan horses are computer programs which pretend to do one thing but actually do damage when they start it. The worms viruses are pieces of software that use computer networks and security flaws to create copies of itself. A cop y of the worm will then scan the network for any other machine that has a specific security flaw, and then replicate itself to the new machine. With regards to email viruses, these use email messages, and usually will copy and automatically mail itself to hundreds of people. There are two generalities of viruses, including resident and nonresident viruses. Resident viruses are those viruses that contain a specific replication module which is alarmingly similar to t hose employed by nonresident viruses. A resident virus is one that stays in memory after it executes, and even after its host program is executed. Resident viruses are often subdivided into categories like fast infectors, and slow infectors. Fast infectors are those particular viruses which are designed to affect as many files as possible and slow infectors are designed to infect hosts infrequently. For instance some slow infectors will only infect files when they are copied. Nonresident viruses on the other hand are those viru ses which consist of a finder module and a replication module. The finder module is responsible for finding new files to infect, while the replication module is the component that actually infects the found files
yes but in hosts by tempering with hosts cell DNA/RNA
Some viruses can move parts of their body, but most viruses rely on their hosts.
Viruses are immobile. They can not move on their own, and rely on their hosts biological systems to move them around.
No. Virus need to rely on hosts to reproduce.
Yes,they live in hosts only to reproduce.
I don't know! Why are you asking me?????
The lysogynistic cycle where they insert their DNA/RNA into the hosts genetic material for many rounds of their own replication along with the hosts replication.
No.
viruses must bind precisely to proteins on the cell surface and than use a hosts genetic system, this is why most viruses are highly specific to the cells they infect

The gray cup host is determined by bidding.
All bacteria use their own ribosomes for protein synthesis while all viruses have to use their hosts' ribosomes. All bacteria have their own energy generation mechanisms (cellular respiration or photosynthesis) while all viruses have no intrinsic energy generation mechanisms.
