Answer:
Gold and silver; these two precious metals have captured a lot of attention during the last year and both printed a strong rally last month. Was this rally due to the safe haven status of gold with silver following suit, or was it bottom fishing? Who knows! Is it a good time to invest in gold and silver, after all they are both at a 4 year low? Let’s investigate this further based on the technical factors of each chart.
Gold and Silver both are still in down trends on the monthly timeframe. Last month’s rally can be considered a normal pullback on this long term basis. The price has pulled back into the monthly chart moving average sell zone, an equilibrium area from which price is likely to take another move lower. The silver monthly chart is more bearish out of the two metals with the strong resistance at around 18.50 which halted last month’s rally.

This can be possible because we no longer need to use a large hose and spray water on the roads and let the dirty water drain away back into seas and rivers and create water pollution. However, this methods requires a large amount of labor and time.
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.
I think it is D.... hope i'm right
