Genetically modified foods are yet available to consumers at the grocery store -false
genetically modified foods have delayed fruit ripening for shell life during transportation -TRUE
Genetically modified foods have enhanced flavor and nutritional content -True
D. butterflies (they eat plants so they are a consumer)
Answer:
That's correct im pretty sure
Explanation:
Because you are adding a nucleotide which is a frameshift mutation.
Answer:
Red blood cells transport oxygen around the body. They are specialised to carry oxygen because they: contain large quantities of a protein called haemoglobin , which can bind oxygen. don't have a nucleus, so there is more room for haemoglobin.
Explanation:
Answer:
Thus, the minimum number of photons per second is 77.34
Explanation:
Light intensity,
= ![5\times 10^{-13} W/m^{2}](https://tex.z-dn.net/?f=5%5Ctimes%2010%5E%7B-13%7D%20W%2Fm%5E%7B2%7D)
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 = ![\pi .r^{2}](https://tex.z-dn.net/?f=%5Cpi%20.r%5E%7B2%7D)
= ![3.14\times \left ( 4.25\times 10^{-3} \right )^{2}](https://tex.z-dn.net/?f=3.14%5Ctimes%20%5Cleft%20%28%204.25%5Ctimes%2010%5E%7B-3%7D%20%5Cright%20%29%5E%7B2%7D)
= ![5.6\times 10^{-5} m^{2}](https://tex.z-dn.net/?f=5.6%5Ctimes%2010%5E%7B-5%7D%20m%5E%7B2%7D)
Let
be the minimum number of photons.
Therefore,
=
x A
=
x ![5.6\times 10^{-5}](https://tex.z-dn.net/?f=5.6%5Ctimes%2010%5E%7B-5%7D)
=
W
Thus the minimum number of photons is given by
![N_{min}=P_{min}/E](https://tex.z-dn.net/?f=N_%7Bmin%7D%3DP_%7Bmin%7D%2FE)
where E = ![hc/\lambda](https://tex.z-dn.net/?f=hc%2F%5Clambda)
= ![\left (6.63\times 10^{-34}\times 3\times 10^{8} \right )/548\times 10^{-9}](https://tex.z-dn.net/?f=%5Cleft%20%286.63%5Ctimes%2010%5E%7B-34%7D%5Ctimes%203%5Ctimes%2010%5E%7B8%7D%20%20%5Cright%20%29%2F548%5Ctimes%2010%5E%7B-9%7D)
= ![3.62\times 10^{-19} J](https://tex.z-dn.net/?f=3.62%5Ctimes%2010%5E%7B-19%7D%20J)
Therefore,
= ![\frac{2.8\times 10^{-17}}{3.62\times 10^{-19}}](https://tex.z-dn.net/?f=%5Cfrac%7B2.8%5Ctimes%2010%5E%7B-17%7D%7D%7B3.62%5Ctimes%2010%5E%7B-19%7D%7D)
= 77.34 photons per second
Thus, the minimum number of photons per second is 77.34
