Answer:
miRNA ( micro RNA )
Explanation:
The small RNA molecule that interfere with gene expression are miRNA. The miRNA is micro RNA that are non-coding molecules of RNA. These small RNA regulate gene expression after transcription (post transcription). 
The miRNA binds to 3' UTR region (untranslated region ) and halt the process of protein production and thereby silencing mRNA.

Explanation:
it should be around -11.5. you read the scale at the upper meniscus, and the readings are as follows:
from down to up:
 -15, -14, -13, -12, -11, -10.
 
        
             
        
        
        
The correct answer is: D. The red blood cells were placed in a hypotonic solution. Water moved from the outside of the cells to the inside of the cells until the cells burst.
Hypotonic solution can be described as solution that has less solute and more water (H2O) than another solution. In order to maintain homeostasis, the water will move (via osmosis) into the cell, through the semipermeable membrane of the red blood cell.
