It's the 4 the answer I hope it has served you
For the second one it’s B or C, I dunno if phototropism is a real word cuz all the rest are vital.
Answer: i believe it’s A and C
Explanation: i took biology and remember these lessons
<h2>Visible spectrum of photon emission</h2>
Explanation:
- An action spectrum is ordinarily plotted so that the "activity" appeared on the y-axis is estimated with an equivalent number of photons at every wavelength of the unmistakable range. In any case, our sun doesn't emanate equivalent quantities of photons at every wavelength.
- Rather, the sun transmits the most photons in the yellow piece of the range, with moderately fewer photons discharged in the red and violet-blue pieces of the range. In this manner, the red and violet-blue districts of Engelmann's action spectrum were estimated with fewer photons than in the yellow piece of the range.
- To correct for this, you need to consider how expanding the quantity of photons in the red and violet-blue pieces of the range - to coordinate the emission level in the yellow part- - would change the measure of oxygen created, and therefore the number of microscopic organisms that amassed, in the red and violet-blue spectral region. The rectified action spectrum would show higher tops in the red and violet-blue pieces of the range, yet the plot in the yellow piece of the range would be around equivalent to Engelmann's.
