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:
The world systems theory is a fundamental social evolution theory which states that, some developed countries such as core nations benefit while other countries such as peripheral (underdeveloped) nations are being exploited significantly.
According to world systems theory, peripheral nations become economically dependent on core nations, which keeps them at a low level of modernization.
Basically, the world systems theory divide the world into three (3) main categories and these includes;
I. Peripheral nations: these includes countries that provide cheap labor and other resources for the core nations. Some examples of peripheral nations are Haiti, Nigeria, Kenya, Sudan, Philippines, Chad, Niger etc.
II. Core nations: these are technologically advanced and well-developed countries that benefit from peripheral nations. Some examples of core nations are Germany, China, Japan, United States of America, England, France etc.
III. Semi-peripheral nations: these includes countries that are in between core and peripheral nations such as developing countries.
D) The war did not change the governments.
The Korean War broke out in 1950 and lasted for roughly three years. North Korea established the Communist-aligned Democratic People's Republic of Korea while South Korea settled into liberal democracy (after alternating periods of autocracy and democracy). Both claims to be the true and sole government of the whole of Korea and believes the border to be temporary.
Answer:
Motor neurons- Ashley's motor neurons allow her to press the gas pedal in her car.
Retinal disparity- Ashley uses the difference between the images on her two retinas to judge the distance between her car and the car in front of her.
Heuristic- When Ashley got lost, she decided to call her parents for help.
Procedural memory- Because she has been driving for several years, Ashley can steer and control the speed of her car.
Circadian rhythms- Because she has to cross different time zones, Ashley will have to drive when she would normally be asleep, putting her at risk for an accident.
Inattentional blindness- Because she wasn't paying attention, Ashley didn't see the car in front of her, and she rear- ended it.
