Eye Color

Eye color is a polygenic trait and is determined by the amount and type of pigments in the eye's iris. Humans and animals have many phenotypic variations in eye color. In human eyes, these variations in color are attributed to varying ratios of eumelanin produced by melanocytes in the iris. The brightly colored eyes of many bird species are largely determined by other pigments, such as pteridines, purines, and carotenoids.
Three main elements within the iris contribute to its color: the melanin content of the iris pigment epithelium, the melanin content within the iris stroma, and the cellular density of the iris stroma.

Eye colors can range from the most common color, brown, to the least common, gray. Rare genetic specialties can even lead to unusual eye colors: black, red, and violet. Eye color is an inherited trait influenced by more than one gene, these genes are being sought using associations to small changes in the genes themselves and in neighboring genes.

The actual number of genes that contribute to eye color is unknown at present, but there are a few likely candidates. Iris color can provide a large amount of information about an individual and a classification of various colors may be useful in documenting pathological changes or determining how a person may respond to various ocular pharmaceuticals.

There are 3 true colors in the eyes that determine the outward appearance, brown, yellow and blue. How much of each color one has determines the appearance of our eyes color. The color of the eyes in turn depends on how much of these colors are present. For example, green eyes have yellow and some blue, making them appear green. Brown eyes appear brown because most of the eye contains the brown color.

COLOR GREEN

Green is a color, the perception of which is evoked by light having a spectrum dominated by energy. In the subtractive color system, it is not a primary color, but is created out of a mixture of yellow and blue, it is considered one of the additive primary colors. The complement of green is magenta; that is, a purple color corresponding to an equal mixture of red and blue light. On a color wheel based on traditional color theory, the complementary color to green is considered to be red.

The word green is closely related to the Old English verb growan, “to grow”. It is used to describe plants or the ocean. Sometimes it can also describe someone who is inexperienced, jealous, or sick. In America, green is a slang term for money, among other things. Several colloquialisms have derived from these meanings, such as “green around the gills”, a phrase used to describe a person who looks ill.

Several minerals have a green color, including the emerald. Animals such as frogs, lizards, and other reptiles and amphibians, fish, insects, and birds, appear green because of a mixture of layers of blue and green coloring on their skin. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize. Many creatures have adapted to their green environments by taking on a green color themselves as camouflage.

Culturally, green has broad and sometimes contradictory meanings. In some cultures, green symbolizes hope and growth, while in others, it is associated with death, sickness, envy or the devil. The most common associations, however, are found in its nature.

Green is also associated with regeneration, fertility and rebirth for its connections to nature. Recent political groups have taken on the color as symbol of environmental protection and social justice, and consider themselves part of the Green movement, some naming themselves Green parties.

How to spend your weekend

If you want to go on vacations this ¨puente¨ but you don’t have enough money you should visit a circus, that`s a good idea.. Check this information. a circus is most commonly a traveling company of performers that may include acrobats, clowns, trained animals, trapeze acts, hoopers, tightrope walkers, jugglers, unicyclists and other stunt-oriented artists. The word also describes the performance that they give, which is usually a series of acts that are choreographed to funny music. A circus is held in an oval or circular arena with tiered seating around its edge; in the case of traveling circuses this location is most often a large tent called the big top.
The origin of the circus were in Ancient Rome the circus was a building for the exhibition of horse and chariot races, equestrian shows, staged battles, displays featuring trained animals, jugglers, and acrobats. The circus of Rome has been influenced by the Greeks, with chariot racing and the exhibition of animals as traditional attractions.
The Roman circus consisted of tiers of seats running parallel with the sides of the course, and forming a crescent around one of the ends. The lower seats were reserved for persons of rank. In Ancient Rome the circus was the only public spectacle at which men and women were not separated. The Latin word circus comes from the Greek word kirkos meaning “circle or ring”
The first circus in Rome was the Circus Maximus, in the valley between the Palatine and Aventine hills. Next in importance to the Circus Maximus in Rome was the Circus Flaminius.
Following the fall of Rome, Europe lacked a large and animal rich circus. Itinerant showmen traveled the fair grounds of Europe. Animal trainers and performers are thought to have exploited the nostalgia for the Roman circus.

The power of....

Hello classmates! I have a recommendation to you that could be really helpful in stressful days, yesterday I read an article about aromatherapy… it was so interesting.
Scientist assumes that aromatherapy is a form of alternative medicine that uses unstable liquid plant materials; recently it has been reported in the news, internet and magazines the powerful of this alternative. Some people used to call essential oils and other aromatic composed from plants for the purpose of affecting a person’s health. Scientific evidence appears but mildly encouraging for a limited number of claims. Essential oils differ in chemical composition from herbal ones; because of the distillation process only recovers the lighter phytomolecules.
For this reason essential oils are rich in monoterpenes and sesquiterpenes, as well as other substances well know as an esters, aromatic compounds, and some organic sulfides
Aromatherapy is a generic term that refers to any of the various traditions that make use of essential oils sometimes in combination with other medical practices and spiritual beliefs. The most popular uses of these products include massaging products, medicine, or any topical application that incorporates the use of essential oils to their new products. It has a particularly Western currency and persuasion medical treatment involving aromatic compounds may exist outside of the West, but may or may not be included in the term ¨Aromatherapy¨.
I wish that the information could really helps you in order to reduce your stress levels and you were enjoying this free day.
