Answer:
Rods.
Explanation:
There are two types of photoreceptor cells, the cones, and the rods.
The cones adapt our vision to bright light and allow us to see colors. On the other hand, rods photoreceptors make us see in the dark and do not perceive many colors; that is why we can not distinguish colors in the dark. Also, they provide peripheral vision since they are on the external edges of the retina.
consciousness is rooted in the midbrain
Answer:
Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones.
The capsid is the protein shell that surrounds the core of a virus where its nucleic acid is located. The capsid is made up small sub units called capsomeres.
A virus consists of a nucleic acid which may either be RNA or DNA and is found in varying quantities in the virus. It is this nucleic acid that is vital to the virus' survival that is housed in the capsid.
A drug that targets the capsid and damages it will cause the nucleic acid to leak out of the virus and into the surrounding while other fluids foreign to the virus will get in rendering the virus totally impaired, and due to this the virus cannot survive but will speedily die.
