Answer:
Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population. Usually it is expressed as a proportion or a percentage. In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool.
The hemoglobin holoenzyme (active enzyme) is a complex of an iron ion and 4 subunits- 2 hemoglobin alpha and two hemoglobin beta. People with sickle cell disease have mutated beta hemoglobins. The mutation is a single nucleotide exchange, that changes the 6th amino acid of protein primary struture - a Glutamic acid into Valine. This one alteration changes the tree dimentional structure of hemoglobin beta so, that it forms lond fibres that disrupt the normal circular form of the red blood cells.

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
Radius of the eye, r = 4.25 x m
∴ Area of the eye, A = 
= 
= 
Let 
be the minimum number of photons.
Therefore, = x A
= 
x 
= 
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
