<u>Answer:</u>
You try to pick up a shell in the water but it isn't where it appears to be is an example of diffraction
<u>Explanation:</u>
Diffraction refers to the light bending that happens as the light passes about the edge of some object. How much bending takes place is found by the size of wavelength of light relative to that of opening. If the opening is larger than the wavelength of light, then bending will not be noticeable.
Since, light gets diffracted due to water hence the shell kept inside the water appears to be at a different position than where it actually is
 
        
             
        
        
        
Prophase 
During the prophase stage of mitosis, the nucleus seems to disband itself. The nucleolus suspends itself and finally, the nuclear membrane disassembles itself. This is because of the undergoing process of copying and dividing. 
Mitosis is a functional cell dividing process that helps the cells repair or rejuvenate itself because of apoptosis and other factors.
