Because you might have just done something different with the experiment and messed up someway during the test
 
        
                    
             
        
        
        
NADPH is the reduced form of NADP+. This simply means that NADPH has an extra hydrogen ion.
NADPH is formed when upon the reduction of NADP+ . NADP stands for nicotine amide dinucleotide phosphate. It is a coenzyme that is involved in a wide range of anabolic reactions.
During the synthesis of carbohydrates in plants, NADPH acts as a reducing agent, likewise in the synthesis of nucleic acids and lipids.
As a reduced compound, NADPH becomes a molecule with high energy thus being especially useful in driving the Calvin cycle.
        
             
        
        
        
In the lytic  cycle, a virus that has invaded and  entered a  cell takes over the cell's replication mechanism. The virus makes viral DNA and viral proteins. 
The virus then lyses (breaks open) the cell membrane, allowing the newly  produced viruses to leave the now disintergrated host cell to infect  other new cells.
The lytic cycle is considered  the main method of viral replication. It is even more common than the lysogenic cycle. It has helped scientists understand better how the immune system responds  to pathogens.
 
        
                    
             
        
        
        
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible. 
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.
hope this helps :)
