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.
The correct answer is easy child.
No child is undemanding - parents have to be around their baby at all times, caring for it, and tending to its every need. But this child can easily adapt to anything, which is why she doesn't really take up a lot of her parents' time, and doesn't cause problems.

The countercyclical policy is complementary to the downfall of GDP. The preferred countercyclical policy is frequently monetary strategy.
Consumer spending decreases and total demand falls during a recession, which allows the government to implement a countercyclical policy to the way the economy is moving. Such a countercyclical policy would result in the intended expansion of output (and employment), but would also raise prices because it would expand the money supply. Increased demand will put pressure on input costs, particularly labor, as an economy draws closer to operating at maximum capacity. Hence, workers then spend their extra money on more products and services, which drives up prices and wages and accelerates overall inflation, an outcome that governments often try to prevent with countercyclical policy.
