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.
A. the government spent money on the military and weapons and neglected the rest of the economy
One of the biggest lessons that can be learned from systemic racism is that public and governmental institutions are built to encourage this type of racism and it is up to us to fight it.
<h3>What is systemic racism?</h3>
- It is a type of maintenance of prejudice against social minorities.
- Public, private, and governmental institutions can establish themselves to maintain racist concepts.
Systemic racism prevents people from being treated equally, as they should be, and creates a system to disadvantage social minorities, especially African Americans, at all costs. This type of system is highly harmful as it impedes social advancement, equality, and justice, making the State flawed and inefficient.

It is quite subjective - it deals with determining how important the text is to you according to some personal criteria.
