Answer:
This is an incomplete question. 
Below should be the complete one with options:
A researcher introduces a signal produced by bacteria to eukaryotic cells that she is culturing in the laboratory. Remarkably, she notices that this signal results in an increase in eukaryotic gene expression. How is this possible?
A.This gene expression is likely independent of the presence of the prokaryotic signal.
B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.
C.This signaling pathway might actually be utilized by both prokaryotes and eukaryotes.
D.This signal is likely similar in structure to ligands utilized by eukaryotic cells.
E.This prokaryotic signal likely travels directly into eukaryotic cells and acts as a transcription factor.
THE CORRECT ANSWER IS B
B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.
 
        
                    
             
        
        
        
Our lymphatic systems act to drain lymph from our tissues, empties and redirects it back to the bloodstream. Therefore, blood vessels remove the venom which is to be drained by our lymphatic system, cycle repeats until no venom is left.
