Cones are concentrated at the center of retina called fovea centralis where no rod cells are present.
The retina is the innermost lining of the eye, made up of thousands of light-sensitive cells, with an inner part of nerve tissue and a pigmented outer part. It plays a fundamental role in the formation of images, which will be projected and then sent to the brain, through electrical impulses.
The retina consists of three types of layers: bipolar neurons, ganglion neurons and photosensitive cells.
Bipolar neurons promote the union of photosensitive cells with ganglion neurons, which are grouped with nerve fibers and thus originate the optic nerve. It carries nerve impulses to the brain. Photosensitive cells, due to their shape, are named in two types: cones and rods.
There are about 6 million cones that are concentrated in a small depression located in the macula lutea (center of the retina) called the fovea. They have an elongated and cylindrical shape, with conical outer segments. It is in this region that the image is most clearly formed, as they are stimulated by the most intense light. Cones are specialized in the accuracy of daytime vision and in recognizing color. There are three types of cones that have fundamental photopigments that respond to light of wavelengths (λ): cyanopigment - S cones (short λ) - sensitive to blue color, chloropigment - M cones (medium λ) - sensitive to green color and erytopigment - cones L (λ long) - sensitive to red color. The brain interprets the signals received by these cones, which allows it to process color differentiation.
Answer:
True
Explanation:
Manchester encoding is a form of digital encoding (or a data modulation technique) in which data bits alternate from high to low or low to high in equal manners. It also allows data senders to easily synchronize with the receiver. Manchester encoding is introduced for security of data and fast transmission.

A border is a line showing the boundaries between states or countries. So, a border state can be likened to a state that marks the territory of one country. Border States are those states that do not that did not want to join Confederacy, they are also known for their involvement in slave trading. Some of the border states are Maryland, Delaware, West Virginia and so on.
The importance of the location of Maryland border and that of Delaware is that they both contributed to the success of the Union because of their loyalty towards the Union during the war. Also, these border states have good lands for the production of crops, they have fertile land for farming which also contributed immensely during the war.
