In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are:<u> more </u><u>sensitive</u><u> in the dark than </u><u>cones</u>.
The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.
Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.
- The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).
- Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.
- On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).
Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

Answer:
C. There is not enough light.
Explanation:
In the aphotic zone, there is not enough light for photosynthesis to occur in plants, so, the plants unfortunately die.
Answer:
nitrogen fixation; denitrification
Explanation:
<em>In a typical nitrogen cycle, the nitrogen in the atmosphere is converted into ammonia in a process known as </em><em>nitrogen fixation</em><em>. The ammonia is then converted into a usable form (nitrate or nitrite) for plants and other living organisms in a process known as </em><em>nitrification</em><em>. Nitrogen is returned to the atmosphere in a process known as </em><em>denitrification</em><em>. </em>
Hence, the correct words to fill the gaps would be nitrogen fixation and denitrification.
