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.

Question: How does oceanic crust move along mid ocean ridges
Answer: Oceanic crust slowly moves away from mid-ocean ridges and sites of seafloor spreading
Explanation: as a result it becomes cooler, more dense, and more thick.

Answer:
Radioactive decay means the process by which unstable nucleus of an atom spontaneously releases energy through the emissions of radiation used in dating fossils and rocks.
Relative dating mean the time required for half the atoms in an element to divide in half.
Explanation:
So radioactive decay belongs to A.
And relative dating belongs to B.

Answer:
Cross the flies with the flies from another population
Explanation:
Inbreeding is the mating between the closely related individuals of a population. Inbreeding reduces the viability of the progeny over a generation since it increases homozygosity. When the flies of a small population interbred over generations, the increased homozygosity reduces the viability of the flies. To counteract it, one should mate these flies with the flies from another population. This would increase heterozygosity and thereby would increase the survival and fitness of the progeny.
In Emphysema, one form of chronic obstructive pulmonary disease (COPD), alveolar walls breakdown, alveoli fuse creating more open spaces, and the lungs lose their elasticity. The result is "trapped air" which becomes difficult to expel upon expiration, thus an expiratory condition.
