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:
a lack of resources would most likely decrease a population size because it will limit growth and decrease survival rates. There will also be more competition.
Explanation:
Please don't plagiarize. Thanks :)
The right option is; A. Prokaryotic cells have a nucleus
''Prokaryotic cells have a nucleus'' is the statement about prokaryotic cells that is NOT true.
Prokaryotic cells are cells that lack a true nucleus and some other cell organelles. Prokaryotic cells are found in unicellular organisms called prokaryotes. Examples of prokaryotes are; Bacteria and Archaea. The components of prokaryotic cells include plasma membrane, cell wall, cytoplasm, nucleoid, ribosomes, DNA (deoxyribonucleic acid). Most of the prokaryotic’s DNA (genetic material) is located in a middle area of the cell (nucleoid), and it contains a single large loop known as a circular chromosome.
