Answer:
Answer is sigma.
Explanation:
The sigma factor can be described as protein regulating transcription in bacteria. That is, it enables the synthesis of RNA at specific locations in DNA. This specific location is known as promoters.
The sigma factor is also known as specificity factor, because, it is specific for the gene.
Transcription can be explained as the process by which genetic information in the DNA strained are copied into a new molecule of mRNA, through the aid of RNA polymerase.
It should be noted that, when there is an increase in pressure, at constant temperature, the stability of elongation complex will decrease. This means that, temperature determines the pressure at which transcription elongation stops.
Answer:
4 ATP molecules
Explanation:
Normally, about 11 ATP molecules are generated as the result of Beta-Oxidation of saturated fatty acid in Kreb's Cycle. But the total removal of acetyl-CoA under certain aerobic condition decreases the overall yield and approximately 4 ATP molecules comes out from each removal of acetyl-CoA.
According to Charles Darwin's theory of Evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

One word answer:Adaptation:
Answer:
I think option B is right answer
Answer: Option E.
All of the above.
Explanation:
Streptococci pyogenes is a disease caused by streptococci bacteria. These bacteria are gram positive ,non sporeforming and non motile.
The virulence factors are substance produced by bacteria to ensure their effective attack.
The virulence factors of S. Pyogenes are;
Spiky M proteins and lipoteichoic acids which they use as attachment to host organisms.
Hyaluronic capsule which the use to slow or inhibit phagocytosis.
Polysaccharide cell wall which causes the rash of scarlet fever.
