<span>The right anwer is (b). Indeed, some scientists consider viruses as non-living because viruses do not undergo mitosis, which is the usual way living cells reproduce themselves. On the contrary, viruses inoculate their genetic material in a host cell in such a way to force the cell to make a copy of the virus DNA, thus making more viruses, that then kill the host cell and disseminate themselves. In practice the viruses exploits the replication tools of the living cells to replicate themselves, since they lack the machinery and also they lack something resembling cell metabolism, i.e., they do not "eat" or "grow".</span>

The right answer is b.viruses do not undergo mitosis.

*Viruses, like HIV, are able to multiply at high speed once they have parasitized a cell.

*By definition, a living organism is born, feeds, grows, reproduces and dies.

Since they are without metabolism, viruses appear to be closer to inert matter, although their reproduction binds them to life. So, the debate is still open regarding the classification of viruses among living or not.

Which of the following statements best provides evidence of the big bang theory?
Oxana [17]

Answer: D. Galaxies show a red shift, indicating they are moving away from each other.

Explanation:

Galaxies seem to show a red shift which indicates that the galaxies are moving away from each other. This provides evidence for the Big Bang theory because the theory posits galaxies will keep moving away from each other.

This is because when an explosion happens, matter moves away from the point where the explosion happened. If the Big Bang happened therefore, galaxies will move away from the source which is why galaxies are moving away from each other.

What would be the main problem if every trait followed a blending pattern?
Alona [7]

Answer:

Blending inheritance leads to the averaging out of every characteristic, which as the engineer Fleming Jenkin pointed out, would make natural selection impossible if blending were the mechanism of inheritance.
