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
The answer to this would be D: physical components of the environment, such as rocks and sand. The word "biotic" mean all the living organisms within an ecosystem such as plants and animals.
<span>During ejaculation, the sperm is sent out from the epididymis into the deferent duct which then travels up the spermatic chord into the pelvic cavity. The first organ that sperm pass through is the epididymis ejaculatory duct . During this time rhythmic movements propel the sperm forward.</span>
Photosynthesis Is generally the opposite of cellular respiration. To drive the organisms metabolism photosynthesis has an exothermic reaction.
Answer:
Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence.
