Answer:
Sigma factor is the name of the protein and it helps RNA polymerase to recognize promoter.
Explanation:
RNA polymerase is the enzyme which helps in the transcription of DNA duplex. In bacteria, a protein called sigma factor is present in RNA polymerase which is responsible for the initiation of transcription.
The sigma factors gives the ability to RNA polymerase to recognize the promoter sequence. If the sigma factor is not present in RNA polymerase than this enzyme can not distinguish between promotor and other sequences.
So the sigma factor increases the affinity of RNA polymerase towards promoter and helps in initiation of the transcription. Sigma factor gets released from the core enzyme when the chain reaches 8-9 bases.
It draws a conclusion based on what would best explain one's observations.
Inference is the process where logical consequences evolve from premises that are assumed to be true. Knowledge backed with observations and reasoning as evidence is used to make conclusions. It is also referred to as an educated guess and is not necessarily factual.

- <u>A Lake Is -Not- A Biome</u>
<u></u>
Biomes: T<u>emperate Deciduous Forest, Coniferous Forest, Woodland, Chaparral, Tundra, Grassland, Desert, Tropical Savanna</u>
<u />
A lake is not a biome. A lake can be found in a biome, but a lake is not itself a biome. A biome is a community of plants and animals that have common characteristics for the environment they exist in. Yes, similar species can be found living in a lake, but a lake can be found in a particular biome where there are lots more of the same species.
