its A

because minerals take a long time to form
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:
unconscious
Explanation:
Freud came to conclude that most of the behavior is driven by forces that are way out of our control and that they can be reduced to life (eros) or dead (Thanatos) drives- These forces are strong components that can shape our decisions and are seen in a metaphor:
The unconscious is the hidden part of the iceberg where we are just barely conscious of the surface while the hidden mental processes can be traced back to childhood experiences mostly. At least according to what Freud came to conclude, the unconscious mind is mainly a deposit of sex and destructive or aggressive drives that are impossible to express at the moment of being.
They are continually either repressed or rationalized as the main mechanisms the ego has for balancing inner needs with the outer world
One obvious similarity between both the Northeast and the Southeast is the Atlantic ports for international trade. Both areas contain parts of the Appalachian Trail. Both areas have mountains. They each have their own mannerisms and cultures. Interstate 95 traverses both the Northeast and the Southeast. Both do farming but in different quantities. Both have severe weather patterns with the Northeast being hit by both hurricanes and storms called Nor'easters. The Southeast it often hit by hurricanes. Winter storms are hardly Both suffered great losses from the Civil War and are very proud of their military heritage.
