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 than cones.
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.

Distinguish between smooth endoplasmic reticulum and rough endoplasmic
reticulum (1 point)
Smooth endoplasmic reticulum has ribosomes attached to
its surface
Smooth endoplasmic reticulum has vacuoles attached to its
surface
Rough endoplasmic reticulum has ribosomes attached to its
surface
Rough endoplasmic reticulum has vacuoles attached to its
surface
The smooth endoplasmic reticulum is different from rough endoplasmic reticulum as the rough endoplasmic reticulum has ribosomes attached to its surface which are absent in smooth endoplasmic reticulum. Thus, the correct option is C.
What is Endoplasmic reticulum?
Endoplasmic reticulum (ER) is a large, dynamic structure which serves for many roles in the cell. There are two types of ER which are Smooth Endoplasmic Reticulum (SER) and Rough Endoplasmic Reticulum (RER). The diverse functions of the ER are performed by distinct domains present in the ER consisting of tubules, sheets and the nuclear envelope.
Rough endoplasmic reticulum contains ribosomes on its surface and synthesizes protein, whereas the smooth endoplasmic reticulum does not contain ribosomes and functions to make lipids and detoxify the cell. Large amounts of SER are found in the cells which participate in lipid metabolism and detoxification of the body, such as liver cells.
Therefore, the correct option is C.
