the answer is B cholesterol, which is a direct product of the steroid nucleus.
I believe its is because the fossils of these animals looked like living species and they had a connection to the modern. A fossil is any preserved evidence of life from a past geological age, such as the impressions and remains of organisms embedded in stratified rocks. Fossils are created when organisms die, are in cased in dirt and rock, and are slowly replaced by minerals over time.
Answer:
The transcription rate will slow down in the cells that carry mutant sigma factor.
Explanation:
Sigma factor play an important role during initiation of transcription.The sigma factor binds to the core RNA polymerase(that contains alpha,beta,beta dash and omega subunit) to form hollow enzyme.
The binding to sigma factor to core RNA polymerase initiates the formation closed promoter complex and the release of sigma factor result in the formation of open promoter complex that signals the ending of transcription initiation.
Now if the sigma factor binds tightly to the core RNA polymerase then it will be difficult for the sigma factor to get dissiciated from hollow enzyme,as a result transcription will remain in the initiation phase. So the process cannot enter the elongation phase.
Answer:
by providing a toll-free number in case there are questions about the devices.
Explanation:
One of the best ways to make certain that this does not happen is by providing a toll-free number in case there are questions about the devices. Doing so makes sure that the customers are fully aware and understand the device and what it is doing. This prevents the customer from assimilating other benefits that they may experience which have nothing to do with the provided device into the survey and potentially contaminating the data with false feedback.
