An idiot would tell you that robots would take over the world. I honestly believe we as humans have the ability to make sure we don't go that far.
People, especially most Americans, have a borderline fetish for leisure. If it makes things easy, buy it, buy it, buy it now. Likely, more advancements will be made to make sure people won't have to leave their home via conventional ways to go to work. Basically, we get even more lazy than we already are, all things considered. Not to mention new innovations for war.
Some good can come from this, however. We require an alternative to fossil fuels, so green energy will be a must in the future. Advancements in medicine will thrive, after everyone discovers that there really are cures for almost anything (there's just no money for the doctors in curing the disease, only treating it). A cleaner Earth, a better planet, a better ecosystem.
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:
The steel industry at Pittsburgh enjoys locational advantages. Some of the raw material such as coal is available locally, while the iron ore comes from the iron mines at Minnesota,
