Tobacco mosaic virus has rna rather than dna as its genetic material. in a hypothetical situation where rna from a tobacco mosaic virus is mixed with proteins from a related dna virus, the result could be a hybrid virus. if that virus were to infect a cell and reproduce, what would the resulting "offspring" viruses be like?

Radiometric dating is used to tell the absolute age of materials by studying the decay rate of radioactive isotopes. the decay rates of isotopes are constant and are expressed as .
