Answer:
C. A baby can't survive without help, just like a virus needs a host in order to reproduce.
Explanation:
Viruses are not considered living beings because they are obligate intracellular parasites, composed primarily of nucleic acids (DNA, RNA or both, in some cases).
In other words, viruses have no metabolism of their own, so they cannot survive without infecting a host cell, in which the virus sets in and modifies its metabolism in order to produce more viruses.
It is during these processes that viruses cause disease in parasitized organisms.
“Scientific knowledge can only advance when all scientists systematically use the same process to discover and disseminate new information. The advantage of all scientific research using the Scientific Method is that the experiments are repeatable by anyone, anywhere.”
the radiations that are used to treat cancers are of the gamma type. primarily emitted from cobalt-60 (a radioactive isotope). and it is more controlled than other radiation exposures. i.e. solar radiation which is not controlled.
hope that this helps.
