Answer:
Thus, the minimum number of photons per second is 77.34
Explanation:
Light intensity,  =
 =  
Pupil has a diameter, d = 8.5 mm 
                                       = 8.5 x  m
 m 
Radius of the eye, r = 4.25 x  m
 m
∴ Area of the eye, A = 
                                  = 
                                 = 
Let  be the minimum number of photons.
 be the minimum number of photons.
Therefore,  =
 =  x A
 x A
                                               =  x
 x 
                                              =  W
 W
Thus the minimum number of photons is given by 

where E = 
              = 
             = 
Therefore,  =
 = 
                                               = 77.34 photons per second
Thus, the minimum number of photons per second is 77.34
 
        
             
        
        
        
Answer: When the oxygen-rich blood gets to the cells, the cells receive the oxygen and release the carbon dioxide. The blood with less oxygen and a lot of carbon dioxide returns to the heart. Then the heart returns this blood to the lungs where carbon dioxide is released and oxygen is received.
