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:
The question is incomplete because the options are not given, here are the options from another website.
A .rectal palpation
B.Coggins test
C. castration
D. vaccination
The correct option is B.
Coggins test
Explanation:
This is because coggins test is the test
carried out to check for Equine Infectious Anemia (EIA) antibodies if present in the horse's blood. Blood samples of the horse are collected and must be sent to a state approved laboratory. This test is majorly fine and needed whenever you want to take your horse to a show or whenever you transport your horse across state lines.
Answer:
D) molecules diffuse through transport proteins.
The answer to this question would be: absorbing water.
A lower water potential solution will induce osmosis to plant cells. In this case, the water will move to the plant cells since solution water potential nearby cells are lower. The plant will continue to accept water until the cells bloated, causing the pressure inside cells increases until the water pressure will gradually stop the osmosis. The plant cell rarely burst as it has cellulose wall, unlike animal cells.
Answer:
E all of these are kingdoms
Explanation:
they just are? I dunno how to "explain" a yes or no thing.
