Answer:
The phenomenon is called convergent evolution
Explanation:
Convergent evolution is the name given to the evolutionary phenomenon whereby a similar characteristic appears independently in two unrelated species, that is, that do not have a direct common ancestor from whom they could inherit that characteristic. Similar characteristics resulting from evolutionary convergence are called analogues or homoplasms (from the Greek, “shaped in the same way”). This process is very common and can be explained by natural selection, since similar selective pressures tend to favor similar adaptations.
The presence of a membrane bound nucleus describes the evolution of eukaryotes from prokaryotic organisms. The endosymbiotic theory describes the same, the large cells engulfed the smaller ones, and the engulfed cells were not digested but started living in mutual cooperation with the engulfing cell. Mitochondria and chloroplast are thought to be the engulfed cell
The correct answer for the question that is being presented above is this one:
(1) viruses only: capsid, envelope with glycoproteins, capsomere (core protein)
