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.

What is being referred to as a transmembrane protein-pigment complex is the REACTION CENTER. This transmembrane protein-pigment complex is present in the photosystem. What it does is that acquires energy from the antenna complex. Once the energy is received, this then triggers the an electron that is transported then to the acceptor molecule.

The answer is cocci.
There are three basic types of the shape of bacteria:
- Cocci - spheres,
- Bacilli - rods,
- Spirochetes - spirals.
If a student drew a circular shape, this probably represented sphere. Therefore, the shape of seen bacteria was spherical which suggests that the bacteria must be cocci.
