Answer:
partially permeable
Explanation:
A dilute solution contains a high concentration of water molecules, while a concentrated solution contains a low concentration of water molecules. Partially permeable membranes are also called selectively permeable membranes or semi-permeable membranes. They let some substances pass through them, but not others.
I believe the answer is plants make flowers to attract insects because, plants do nit store carbohydrates, meat does, and we cant use plants to create fossil fuel. The only plant fibers we use for clothing is cotton so that is very limited in the wide aspect of things.
B. They make their own food, Position 1 because all of those animals would have jaws. B. Cellular Respiration, A. They belong to the same kingdom but different phyla.
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
The answer would be <span>photosynthesize. Only plant cells use the process of photosynthesis to create ATP.</span>
