question:What is the final step of the following process: - A machine called a pulverizer grinds the coal into a fine powder - The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace - The burning coal heats water in a boiler, creating steam - Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine - The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy - This happens when magnets inside a copper coil in the generator spin - A condenser cools the steam moving through the turbine - As the steam is condensed, it turns back into water Answer:

question:Q:Given the background: Reptiles are a class of animals comprising turtles, tuataras, lizards, snakes and crocodiles. They are tetrapods, but the snakes and a few species of lizard either have no limbs or their limbs are much reduced in size. Their bones are better ossified and their skeletons stronger than those of amphibians. The teeth are conical and mostly uniform in size. The surface cells of the epidermis are modified into horny scales which create a waterproof layer. Reptiles are unable to use their skin for respiration as do amphibians and have a more efficient respiratory system drawing air into their lungs by expanding their chest walls. The heart resembles that of the amphibian but there is a septum which more completely separates the oxygenated and deoxygenated bloodstreams. The reproductive system has evolved for internal fertilization, with a copulatory organ present in most species. The eggs are surrounded by amniotic membranes which prevents them from drying out and are laid on land, or develop internally in some species. The bladder is small as nitrogenous waste is excreted as uric acid.Turtles are notable for their protective shells. They have an inflexible trunk encased in a horny carapace above and a plastron below. These are formed from bony plates embedded in the dermis which are overlain by horny ones and are partially fused with the ribs and spine. The neck is long and flexible and the head and the legs can be drawn back inside the shell. Turtles are vegetarians and the typical reptile teeth have been replaced by sharp, horny plates. In aquatic species, the front legs are modified into flippers.Tuataras superficially resemble lizards but the lineages diverged in the Triassic period. There is one living species, Sphenodon punctatus. The skull has two openings (fenestrae) on either side and the jaw is rigidly attached to the skull. There is one row of teeth in the lower jaw and this fits between the two rows in the upper jaw when the animal chews. The teeth are merely projections of bony material from the jaw... and the situation: Two continents were known for the strange discrepancies in animal populations. Asia was mostly populated by reptiles of all species, while Africa was mostly populated by birds and very few reptiles. Answer the following question: Which continent was inhabited by fewer turtles? A:

question:Article:The technology was designed by Philips and has been installed at a Carrefour supermarket in Lille. It transmits codes via light waves, which are undetectable to the eye but can be picked up by a phone camera. The innovation offers an alternative to Bluetooth-based "beacons", which are being installed by many retailers. "We are always on the lookout for innovations to facilitate customers' navigation," explained Carrefour executive Celine Martin. "Thanks to this new application, which uses Philips technology, we are now able to provide our customers at the EuraLille Carrefour with a new service, enabling them to quickly search and locate their preferred promotions or detect all the promotions around them." Philips said that an added benefit was that its system required 50% less electricity than the old lights it had replaced. Philips is not the only organisation to have researched ways to transmit data via specialised LED bulbs. Engineers at the University of Edinburgh are working on a "li-fi" system capable of transmitting data at up to 10 gigabits per second, which they suggest could offer an alternative to radio waves. The Philips scheme is more limited in its scope, but has the benefit of being ready for market. It works by making each of the fitted LEDs transmit a distinct location code. If users open a compatible app and let their smartphone camera look upwards, this can be used to determine their location - accurate to up to 1m - and the direction they are facing. It functions in a similar way to GPS-based maps used outdoors, and compares favourably to wi-fi based location systems, which are typically accurate to only 3-5m. Many retailers, however, are investing instead in beacons - small Bluetooth 4 transmitters that allow compatible apps to work out how far away a user is standing, but not their precise position. Beacons have the benefit of being cheaper and potentially easier to try out than replacing a store's complete lighting system. However, one expert saw the merits of Philips's alternative. "You have to look at this as a long-term investment, but this is potentially an easier spend to swallow as you're not just betting on one thing - you still have a good lighting system," commented Chris Green, principal technology analyst at the Davies Murphy Group consultancy. "It also goes far beyond what is achievable with the beacons. "To try and get a similar effect you'd need so many of them that they would be awkward to deploy, plus you'd need to rely on users having a phone that not only supports the newer Bluetooth standard but also has it switched on. "By contrast, this is up in the air, so easier to roll out." A summary of the above article is?
