So the answer is B. Respiration.
The amniotic eggs also has structures for <em>respiration </em>and for storing waste.
The evolutionary advantage of an rna genome in eukaryotic cell virus is that it <span>have another mechanism for genetic diversity.
For example, RNA exchange between mammalian and avain flu--> pandemic flu
It also have advantage to get around limitation that Eukaryotic only encode one protein.
Viral genomes can be made out of either RNA or DNA. The genomes of RNA viruses can be either single-stranded or twofold stranded RNA, and may contain at least one separate RNA particles
