Hi
There many rules John Smith instituted in Jamestown, but the most common one was, "He would does not work, shall not eat".
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:
Nitrogen eventually breaks down
Explanation:
nitrogen is compounded in soil and broken down completely by microorganisms through a process known as nitrification

1. The Greeks were an ancient people who built impressive tombs and temples with a rich mythological traditions. The Greeks were also famous as educationalist and had some the most popular scholars of the ancient world.
As an influential empire on the Mediterranean, The Romans learned from the Greeks, the art of building monuments and many of the Rome's largest buildings have directly been influenced by earlier Greek Designs.
2. The Etruscan culture was based out of modern-day Southern Italy and the Romans also took a lot of inspiration from them, mostly on leisure and sporting events.
The Etruscan culture was based on slave fighting and chariot races. Both of these quickly became famous in Rome. The Romans built large stadiums including the Coliseum of Rome and the Hippodrome of Istanbul to enjoy these sports.
