Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.
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.

Answer:
Spark up Spanish conversations, speak more Spanish, and sound more like a native Spanish speaker with these conversation starters and examples.
Explanation:
1.) B it is not d because it shows a growth in the beak size, it didn't say anything about the birds having larger beaks just that the size increased
2.) A
p=.5 q=.5
q^2=.25 p^2= .25 2(pq)= .5 everything added up is 1.0 so we good
so q^2, which is the recessive gene or gg, is 25 percent
