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:
Scientists have been concerned that human activities could cause more plants and animals to become extinct than any point in the past. Along with human-made changes in climate (see above), some of these extinctions could be caused by overhunting, overfishing, invasive species, or habitat loss
Answer:
They typically have a tough, spiny surface, which inspired their name (in Greek, echinos means “spiny” and derma means “skin”). They also have the unusual ability to regrow lost body parts, and sea stars and brittle stars can regrow arms if broken off or eaten
