They're two different clotting pathways that use different factors. Though, the intrinsic and extrinsic pathways come together at factor X and eventually result in fibrinogen (factor I)  being converted into a fibrin clot by prothrombin (factor II). 
Extrinsic begins with factor VII and intrinsic begins with factor XII
        
             
        
        
        
The arrangement of specialized parts within a living thing is sometimes referred to as levels of organization. Cells, of course, are the first level of organization. In any multicellular organism, cells rarely work alone. Cells that are similar in structure and function are usually joined together to form tissues.

Answer:
e. None of the above
Explanation:
For me as a Researcher, the reason could be increased Concentration of your DNA sample which you are using as your template. Try to decrease the concentration of DNA (up to 100 ng per reaction is enough and can increase up to 200 ng). so the reason for getting non specific bands is increase concentration of DNA  which results in non specific amplification and also degradation of DNA in the reaction which you can see in your gel electrophoresis results.  
i always corrected my results using the same technique that is lowering the concentration of DNA between 100 and 200 ng per single reaction of PCR.
