Why does a virus lethal to us not infect animals? I know that RNA viruses mutate at 10,000 to a million times faster than DNA vi
Setler [38]

The virus needs to speak the molecular language of cells. This is how he manages to dominate and enslave them so that they become factories for new viruses, producing the proteins that the infectious agent requires to assemble its descendants. If this conversation is not fine-tuned, even if the virus has the key and enters, it is doomed to failure.

<h3>Why does a virus lethal to us not infect animals?</h3>

For a virus to be able to enter a cell, it must have the right key. And this key, which are the proteins on the surface of viruses, has to enter the correct lock, the receptors that are on the cell membrane. Cells are actually houses with many different doors and locks. Some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

With this information, we can conclude that some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

kvv77 [185]

Answer:

The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.

Explanation:

Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant. The frequency of an allele to occur in a population will depend on the environmental factors. The alleles which code for traits that are best suitable for living in an environment will be seen in more abundance. The frequency of an allele to occur in a population also depends on the breeding trends of the population.
