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: It is an amino acid that cannot be made by the body. It must be obtained from eating certain foods.

answer:
plasma membrane a microscopic membrane of lipids and proteins which forms the external boundary of the cytoplasm of a cell or in closes a vacuole, and regulates the passage of molecules in and out of the cytoplasm
answer number 2

I think this is a good plan. In this way, it would stop flooding in the future. Trees help absorb water with their roots. It can absorb at least 20% of the flood water.
However, there are also factors that would affect the trees from growing healthily. Some of the trees would not receive the right amount of energy and sediments can possibly be mix with the good soil.
It is best that we examine why the flooding occurred. There could be other possible reasons for flooding. It can be pollution caused by people throwing their garbages anywhere.
Differential reproduction means that some organisms in a population produce more offspring than others.
Differential reproduction refers to the difference between individuals in a population and how many offspring they are able to leave.The best adapted organisms to a given environment will leave more offspring than those who are not well adapted. Differential reproduction depends on the natural
