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.
Answer:
body's water needs, conserving water if the body is dehydrated or making urine more dilute to expel excess water when necessary. ADH is a hormone that helps the body to retain water by increasing water reabsorption by the kidneys.

Terms that are asked to be used in the response are bolded;
Ocean ridges and trenches are related in a few ways. One of the ways is being created from the movement of tectonic plates on the mantle when they diverge and converge. When tectonic plates diverge they "pull apart" and create trenches. When they converge they "push together" and create ridges, subduction happens here. The tectonic plates move on the mantle of magna from convection currents creating these different boundaries.
Have a nice day!

Answer:
POLYADENYLATION mechanism.
Explanation:
This is the mechanism of adding a poly(A)tail to a mRNA to protect the RNA.This tail is made up of adenosine monophosphate(AMP) compound, and therefore consists of only this purine base stretch.(adenine is purines).
Polyadenylation participate in production of mature mRNA for the process of translation in the cystosol, therefore ensuring stability.
However this tail shortened with time, and in extreme shortness the mRNA is degraded by enzymes in the cells.
Conclusively, the protection provided by the poly(A) tail
and production of mature mRNA ensured the stability of these molecules
