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
Answer:
Mutations in introns create alternative splicing site which in turn make mRNA with reduced or no translation.
Explanation:
Introns regulate the splicing of heterogenous RNA during post transcriptional modifications as well as affect the stability of mature mRNA. The stable mRNA is more likely to be translated into proteins. So, introns also regulate the translation of mRNA.
In human beta thalassemia, mutations in intron create alternative splicing sites which in turn affect the formation of beta globin chain of hemoglobin. Lack of beta globin chain reduces the amount of functional hemoglobin and causes anemia.
An organism (example skin) this organism replicates the movement of your body in witch it can move and adjust to the movement.
Mitochondrial DNA is a smaller version of regular DNA; with Mitochondrial only having enough base pairs to create 37 genes. This means that mDNA is was sequenced and is a baseline in phylogenetics. Your answer is going to be "C"
This is false.
Enzymes are actually made up by proteins which can act as a biological catalysts that can speed up chemical reactions. Each of them has an active site, its like a concaved space, and it can bind into specific substrates then combine them to form products.
However, active sites will not be changed and they can bind into more substrates again and again. Just note that the active site may only be changed due to the unfavorable temperature or pH, but otherwise they can be used again and again
