Answer:
B) You measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same. 
Explanation:
In the above scenario, we are using the control gene and we should know about the control gene is that its expression is either at transcription level or at translation level. For this situation we should examine the pre-mRNA stage of control gene in various cells because it is control gene so it should be present in various cells. 
So, the best practice is to quantify the pre-mRNA level of gene then we can effectively solve the experimental problem and find the gene expression either it is at transcription or translation level.

In some places, especially some new wells that have just been drilled, 
the oil is under pressure, and it brings itself to the surface as soon as 
you drill a 'pipe' for it to rise through.
In most oil wells, there's a pump bobbing up and down day and night, 
pumping the oil up out of the well.
When the well is so old that even a pump isn't very effective, water is 
often forced down the well under pressure, and the water forces the 
oil back up through the pipe.
        
             
        
        
        
Answer:
Dependent: Reduction
Independent: Solar Energy
 Controlled: B
Explanation:
The dependent variable is what is being measured in the lab. 
The independent variable is what is being CHANGED by the individual 
The control is what is kept the SAME throughout the lab. 
Hope this helped!
