Double-stranded rna genomes can be found

The RNA genomes that are known as double stranded are found only on viruses. Remember that the Double stranded RNA viruses are a group that vary in many different host ranges like humans, animals funig, etc. One of the members of this group can include the ones called rotaviruses that cause many different type of illnesses like gastritis in children.  

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
