Compound eyes fall into two groups: apposition eyes, which form multiple inverted images, and superposition eyes, which form a single erect image. Compound eyes are common in arthropods, and are also present in annelids and some bivalved molluscs.
Compound eyes, in arthropods at least, grow at their margins by the addition of new ommatidia.
Good fliers like flies or honey bees, or prey-catching insects like praying mantis or dragonflies, have specialized zones of ommatidia organized into a foveal area which gives acute vision. In the acute zone the eyes are flattened and the facets larger. The flattening allows more ommatidia to receive light from a spot and therefore higher resolution.
Another version is the pseudofaceted eye, as seen in Scutigera. This type of eye consists of a cluster of numerous ocelli on each side of the head, organized in a way that resembles a true compound eye.
The body of "Ophiocoma wendtii", a type of brittle star, is covered with ommatidia, turning its whole skin into a compound eye. The same is true of many chitons.
Miyazaki Prefecture
After the Meiji Restoration, the area of Hyūga Province was renamed Miyazaki Prefecture.
Miyazaki is famous for various foods such as meat and fruit.
Miyazaki Prefecture is on the eastern coast of the island of Kyūshū. The southeast coastline faces the Pacific Ocean. Ōita Prefecture is north of Miyazaki. Kumamoto and Kagoshima Prefectures are to the west.
National parks are established in about 12% of the total land area of the prefecture.
Miyazaki is one of only two locations on Earth where the fungus "Chorioactis geaster" lives.
"Tsuno jinja" is the main Shinto shrine ("ichinomiya") in the prefecture.
Thundersnow
Thundersnow is a thunderstorm with snow instead of rain. This rare kind of weather is less rare around the Midwestern United States, the Great Lakes and Rocky Mountains, the Sea of Japan, and Mount Everest. Thundersnow mostly happens in March.
Thunder can be heard many miles away, but thundersnow thunder can only be heard a few miles away. The snow stops sounds of thunder more than rain does.
Alachua County, Florida
Alachua County is a county in the U.S. state of Florida, and was formed on February 29, 1824. As of 2000, the population is 217,955. Alachua County's seat is Gainesville.
Opsin
Opsins are the universal photoreceptor molecules of all visual systems in the animal kingdom.
They change from a resting state to a signalling state by absorbing light. This activates the G protein, resulting in a signalling cascade which produces physiological responses.
This process of capturing a photon and transforming it into a physiological response is known as phototransduction.
Five groups of opsins are involved in vision. Another opsin found in the mammalian retina, melanopsin, is involved in circadian rhythms and pupillary reflex, but not in image-forming.
Some opsins allows vision in just a short stretch of wavelength. This is equivalent to seeing in only one colour. Two opsins allow vision in two colours, and is usual in mammals. Four opsins allows vision in full colour, and is usual in teleost fish, reptiles and birds. In mammals, only Old World monkeys, apes and humans have trichromacy, full colour vision.
It is thought – see evolution of colour vision – that mammals lost much of their colour vision capability during the long period in the Mesozoic when they lived as mostly nocturnal animals.
Sinoceratops
Sinoceratops, whose name means 'horned face from China', was a very large ceratopsian dinosaur. The dinosaur used to live in what is now China during the Upper Cretaceous. "Sinoceratops" is an ancestor of "Styracosaurus" and "Centrosaurus". The head of a full-grown "Sinoceratops" was probably about long.
Crash Bandicoot
Crash Bandicoot may refer to:
Crash Bandicoot 3: Warped
Crash Bandicoot: Warped (known in Europe as Crash Bandicoot 3: Warped) is the third video game for the "Crash Bandicoot" series. Time trials were a new feature introduced with this game.
Crash Team Racing
Crash Team Racing is a racing video game developed by Naughty Dog and published by Sony Computer Entertainment for the PlayStation. The game was released in North America on September 30, 1999. It was released in Europe and Australia later the same year. It was released again for the Greatest Hits chain in 2000.
"Crash Team Racing" is the fourth game in the "Crash Bandicoot" series. It is the first "Crash Bandicoot" racing game and the last to be developed by Naughty Dog. The characters of the "Crash Bandicoot" series, must race against the evil Nitros Oxide and save their planet from destruction. In the game, players can take control of one of fifteen "Crash Bandicoot" series characters. Although only eight are available at first. During the races, speed power-ups and other objects to use for safety, can be used to help the player win the game.
The game received very good reviews from video game critics. They liked its gameplay and graphics. However, the audio had a mixed review. In 2003, "Crash Nitro Kart", was released for the PlayStation 2, Nintendo GameCube, Xbox, Game Boy Advance and N-Gage game consoles. It is not a sequel to "Crash Team Racing". With 2.2 million copies sold, "Crash Team Racing" remains one of the most popular PlayStation and best-selling video games as of 2012.
"Crash Team Racing" is a racing game in which the player controls characters from the "Crash Bandicoot" universe. The characters compete in karts. While racing, the player can accelerate, steer, reverse, brake, hop or use weapons and power-ups with the game controller's analog stick and buttons. There are two different crates that are scattered throughout the tracks and arenas of "Crash Team Racing". Crates with question marks (?) on them have power-ups and weapons. Players must drive through and break the crate. When a player collects a weapon or power-up, it will appear in a box at the top of the screen. Once the player has this, they can destroy other racers with the weapon. The power-ups can help the player's performance. "Fruit Crates" carry "Wumpa Fruit" that increase the speed of the player's kart. This strengthens the player's weapons and power-ups if ten of them are collected.
The power slide can be done by holding down one of the shoulder buttons to perform a hop, and steering before the kart lands. While sliding, the "Turbo Boost Meter" on the lower-right corner of the screen fills up and goes from green to red. To get a speed boost, the player quickly presses the opposite shoulder button while the Turbo Boost Meter is red. The player can get three speed boosts in a row during a power slide. The third speed boost is more powerful. If the player waits too long into the power slide for a boost, the kart will spin around.
Fifteen characters are playable in "Crash Team Racing". However, only eight of them are playable from the start. Crash Bandicoot, the protagonist of the series, is a playable character. Doctor Neo Cortex, Crash's enemy, is a mad scientist. He wants to stop Nitros Oxide so that he may take over the world himself. Coco Bandicoot, Crash's younger sister, is a computer genius. Doctor N. Gin is a rocket scientist. He is Cortex follower and serves his master. Pura and Polar's karts have low speed but better handling. This allows them to get around tight corners. Tiny Tiger and Dingodile's karts are built for top speed.
The main antagonist of the story, Nitros Oxide, believes he is the fastest racer in the galaxy. He warns everyone about his plan to turn planet Earth into a concrete parking lot. There are four bosses: Ripper Roo, Papu Papu, Komodo Joe and Pinstripe Potoroo. The four bosses, along with a mistake clone of Crash Bandicoot named Fake Crash, become playable characters if the Adventure Mode is fully completed.
