Accumulation flooding occurs because the ground is completely filled with water and there is no longer a zone of dry land.
Explanation:
Flood is the overflow of water on the land which is usually dry throughout the year. It occurs when more water comes in the river due to rainfall or breaking of dam. But mostly flood occurs, due to melting of ice on the poles because of global warming. Global warming refers to the increase in average temperature due to presence of greenhouse gases such as carbondioxode, methane and water vapors etc in the atmosphere.
Answer:
C. RNA polymerases.
Explanation:
Bacteria has a primitive type of RNA polymerase while archaeal RNA ploymerase is more advanced and complex than that of bacterial. The structure of archaeal RNA ploymerase has more resemblance with RNA polymerase II of eukaryotes. The RNA polymerase of bacteria requires sigma factor for transcription initiation whereas the RNA ploymerase of archaea requires transcription factors for transcription initiation just like eukaryotes.
Root hairs have hair like extensions which help increase the surface for absorption of water and mineral salts from the soil. It is similar in function to the villi of the intestinal tract which also has hair like extensions to increase the surface area for absorption of nutrients.
