olar bear communication P Polar bear v The polar bear or the sea/ice bear are the world's largest land predators. They can be found in the Artic, Canada, Russia, Denmark (Greenland), and Norway. v In the wild polar bears live up to age 25. v Polar bears have been known to swim 100 miles at a stretch. v Polar bears primarily eat seals. Communication v When a Polar bear wants to play, he communicates this to another bear by wagging his head from side to side. Such play sessions involve ritualised fighting or mock battles. v A mother Polar bear can comfort, protect, or punish her cubs by using her body, muzzle, or paws and scold her cubs with a low growl or a soft cuff. Communication v Among Polar bears, hissing, snorting and a lowered head signifies aggression. An attacking Polar
The Polar Boy A year ago, I decided to go to the cinema and watch something extraordinary. The choice fell on an Estonian film “The Polar Boy”. It is a touching romantic drama film produced in Estonia that premiered on May 13. 2016. The film was directed by Anu Aun and the film stars are Roland Laos and Jaanika Arum. This film focuses on the development of the relationship between two young people - Mattias and Hannah. "The Polar Boy" has been supported by Estonian Film Foundation. Mattias is a young talented photographer living in Tallinn, who has a dream to become a student of the Berlin Arts Academy. He is in his final year of school and has to concetrate on studying before exams, but suddendly he fells in love with a girl. Hannah suffers from a mental disorder called bipolarity. She has periods of depression and periods of elevated mood and it is quite hard for her to control her mood swings
Polar bear Ursus maritimus or the "sea bear." Polar bears live near the circumpolar at north in areas where they can hunt seals at open leads. Scientists estimate that there are between 22000 to 27000 polar bears. Its closest relative is the brown bear. Adult male polar bears are 2,5 to 3 meters tall. They weigh 250 to 770 kilograms. Adult female bears are smaller. They are about 1,8 to 2,5 meters tall and weigh 90 to 320 kilograms. Polar bears usually eat seals usually the ringed seasl, but sometimes the bearded seals. When hunting is good, polar bears will typically eat only the fat and leave the rest of the carcass for scavengers including arctic foxes, ravens, and younger bears. Polar bears also sometimes kill and eat both walrus and beluga whales
Polar Bear Kristjan Paal 6.c The polar bear (Ursus maritimus) is a bear native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest land carnivore and also the largest bear, together with the omnivorous Kodiak bear, which is approximately the same size. A boar (adult male) weighs around 350 700 kg (7701,500 l while a sow (adult female) is about half that size. Although it is closely related to the brown bear, it has
Bears are classified as caniforms, or doglike carnivorans, with the pinnipeds being their closest living relatives. Bears Black bears Black bears live in north America and central and eastern Asia. Black bears are smaller than brown bears. Black bears Polar bear Polar bears live near the north pole. They are good swimmers and the like to ride on pieces of ice.

and the tips of their ears. They have three to four litters a year with one to eight in each litter. The snowshoe rabbit can run up to 27 mph and jump 10 feet in one hop. Since they are herbivores they are mainly prey. They are experts at escaping predators like the wolf, bobcat, or lynx. When a predator chases it, the rabbit will quickly change direction. They are also good swimmers and will jump in the water to make an escape. Polar bear Polar bear is the largest carnivore on land. The polar bear's fur is clear, not white. Light reflects off the fur and makes it look white. Their teeth and claws are very sharp so they can catch their prey easily. They hunt and eat seals, whale and walrus carcasses. In the summer they also eat lemmings, arctic foxes, ducks and some plants. They live for 15 to 20 years and spend most of their time on drifting packs of ice, eating and resting.

called ice fjords, in which glaciers from the ice caps pass through valleys to the sea, where they form thousands of icebergs each year. The climate is extremely cold, although the south experiences a short summer. The mammals of Greenland are more American than European and include muskox, wolves, lemmings, and reindeer. The varieties of seal and whale, and most of the species of fish and seabird, are also American rather than European. Circumpolar animals, such as polar bears, arctic foxes, polar hares, and stoats, are also found. Greenlanders are a people of mixed ancestry, primarily Inuit and European, especially Danish Norwegian. Nearly all live on the narrow southwest coastal fringe. Fishing, sealing, and
4. How are plants adapted to life in the biome? Tundra plants are small -- usually less than a foot high .The hairs on the stems of many tundra plants, such as the Arctic crocus, help to trap heat near the plant and act as protection from the wind. Plants adapted to the tundra have small waxy leaves to prevent the loss of precious water in this dry environment. Quick-Developing, Cup-Shaped Flowers Soil Not Needed for Growth Polar Desert- Plants that grow in the Arctic regions must be very hardy and adapted to the extreme winter cold of these environments. Polar desert plants have a summertime growing season, but in the Arctic and Antarctic that season is short---often wildflowers and the other plants that manage to survive here are active only from June to July Alphine biome- Because of the blustery weather, most plants are small groundcover plants, which grow and reproduce slowly
Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may rise a predicted from 2 to 6 degrees Celsius

More than 3,000 musk oxen live in the area around Kangerlussuaq Airport and some of them can be seen in the immediate surroundings. A one-hour guided tour of the area will most likely include an encounter with these large, sedate animals. Reindeer live all over the ice-free parts of Greenland, and you may be lucky to see a herd. Reindeer hide is very insulating, and if you decide to go on a dog- sledge tour you will have the chance to dress in clothes made from reindeer hide. Polar bears live predominantly in north and east Greenland but also come to south Greenland, drifting on the field ice. Encounters with polar bears are extremely rare except in north and east Greenland and no precautions are necessary outside these regions. The northeastern part of Greenland is a protected national park. With a size larger than England and France put together, it's the largest national park in the world.

NORTHERN LIGHTS LIINA VIROLAINEN 12A CLASS KEILA KOOL NORTHERN LIGHTS Northern lights is a common name for the Aurora Borealis in the Northern Hemisphere. Where can we see the northern lights? The Northern Lights, as the name suggests, are especially related to the polar regions. They occur most frequently in a belt of radius 2500 km centered on the magnetic north pole. This so-called auroral zone extends over northern Scandinavia, Island, the southern tip of Greenland and continuing over northern Canada, Alaska and along the northern coast of Siberia. How often can you see the Northern Lights? In Troms and Finnmark, we can see the Northern Lights every other clear night, if not even more frequently. From southern Norway, only a few times a

to need less body fat to survive while others are struggling for food. In the next few decades, some types of mammals, fish, birds and plants are getting smaller and evolve into miniature versions of what they are today. This could force some creatures, that people eat, to become extinct, Dr David Bickford from the National University of Singapore reviewed research showing creatures from deer to tortoises, gulls, goshawks and even polar bears have already shrunk over the past 50 years. 'Because recent climate change may be faster than past historical changes in climate, many organisms may not respond or adapt quickly enough. The species that can adapt are the species that will be affected by potential declines in body size.' Researches say warmer and drier conditions have seen an increase in droughts which have shrunk some plants, and acidification of the ocean has affected the size of algae and plankton

Mating and breeding Humpback whales reach sexual maturity at 6- 10 years of age or when males reach the length of 11.6 m and females reach 12 m. Each female typically bears a calf every 2-3 years and the gestation period is 12 months. The calf is between 3-4.5 m long at birth, and weighs up to 907 kg. Distribution and migration Is found in all the world's oceans. Most populations of humpback whales follow a regular migration route. They are summering in temperate and polar waters for feeding. They are wintering in tropical waters for mating and calving. Status Because their feeding, mating, and calving grounds are close to shore and because they are slow swimmers, the humpback whales were an easy target for early whalers. The International Whaling Commission (IWC) gave them worldwide protection status in 1966, but there were large illegal kills by the Soviets until the 1970's. It is believed they number about 30,000-

The soil is very low in nutrients and minerals, except where animal droppings fertilize the soil. Although there isn't a lot of biodiversity, only 48 species of land mammals are found on the tundra, there are a lot of each species. These consist of slightly modified shrews, hares, rodents, wolves, foxes, bears and deer. There are huge herds of reindeer in North America that feed on lichens and plants. There are also smaller herds of musk oxen. Wolves, wolverines, arctic foxes, and polar bears are the predators of the tundra. Smaller mammals are snowshoe rabbits and lemmings. There aren't many different species of insects in the tundra, but black flies, deer flies, mosquitoes and "no-see-ums" (tiny biting midges) can make the tundra a miserable place to be in the summer. Mosquitoes can keep themselves from freezing by replacing the water in their bodies with a chemical called glycerol. It works like an antifreeze and allows them to survive under the snow during the winter

Nii salvestati kuulsa rootsi rezhisööri Lasse Hallströmi käe all ABBA Austraalia turnee ning sellele pikiti vahele lugu raadio DJ-st Ashleyst (näitleja Robert Hughes), kes soovib ansambliga intervjuud teha. Filmi sissejuhatav Please Change Your Mind on Benny ja Björni kirjutatud ning selle esimene realiseering oli stuudiomuusikutest koosnev ansambel Nashville Train albumil "ABBA Our Way" (Polar POLS 278), millel on 12 ABBA lugu esitatud country-stiilis. Plaat ilmus 1977. aasta alguses ning aasta hiljem anti see välja ka Ameerikas (RCA AFL1-2630).
pandas, which costs five times more than that of the next most expensive animal, an elephant. American zoos generally pay the Chinese government $1 million a year in fees, as part of a typical ten- year contract. On the other hand, zoos can be useless to keep specific animal species because they do not give their residents accurate copy of natural habitat. Lions can not have an active lifestyle because the area around them is too small and as for polar bears, who need low temperature for existence it is impossible to turn zoo into so said natural habitat. In conclusion, zoos are necessary alternatives to a natural environment. Not only zoos can protect animals from being poached, but also can help research centers, that try to find the solution to rebuild original natural environment and help animals to reproduce. There are big organizations such as UNESCO and WAZA that are sure that zoos are irreplaceable.
Euroopa suveaeg), Maal registreeriti selleks kell 20:06. Pathfinderi maandumiskohaks valiti Ares Vallis (Arese org). See asub Viking-1 maandumiskohast 850 km kaugusel Marsi põhjapoolkeral koordinaatidega 19,5° põhjalaiust ja 32,8° läänepikkust. Välja valiti ta sellepärast, et miljardeid aastaid olid seal voolanud võimsad veevood, mis tõid sinna pinnast ka kaugematest piirkondadest. 1999. aasta 3. jaanuaril startis Mars Polar Lander (MPL). Tema ülesandeks oli otsida planeedilt vett ja uurida selle kliimat. Seadmetest olid MPL-il kaasas kopp (2 m pikk) pinnaseproovide võtmiseks, mikrofon Marsi häälte kuulamiseks, kaamera, mis tegi pinnaseproovidest pilte, teine kaamera mis tegi

Bank Rock Bridge. 5) Central Park Zoo The zoo began in the 1860s as a menagerie, making it the first official zoo to open in New York. It is part of a system of four zoos and one aquarium. The zoo is home to an indoor rainforest, a leafcutter ant colony, a chilled penguin house, and a Polar Bear pool. 6) Central Park Carousel – was installed in 1951 and it is one of the largest merrygorounds in the United States. There are 58 handcarved horses and two chariots. The carousel originally was installed in Coney Island in Brooklyn. 7) Strawberry Fields On John Lennon's 45th birthday, New York City dedicated 2.5 acres to his memory. Countries from all around the world contributed trees,
About 91,000 insect species have been described. In America, there are very many parks, which 58 are national parks and there are hundreds of federally managed parks, forests and wilderness areas. The first national park in the world was Yellowstone national park in Wyoming. http://www.youtube.com/watch?v=3iaSlZE-Wxs&feature=related Many species became extinct soon after the first settlements. The U.S. climate is temperate in most areas, tropical in Hawaii and southern Florida, polar in Alaska, semiarid in the Great Plains, Mediterranean in coastal California and arid in the Great Basin. The droughts and floods are infrequent in America. In north Alaska was recorded the lowest temperature in U.S. -62.2 °C . The highest temperature was recorded in California in Death Valley when the temperature reached 57 °C. The flora is so diverse in America because of the different climates and good weather in some places (like California). National bird is bald eagle

Ala with its small side-chain is found equally in the interior and on the surface and is a very abundant amino acid in proteins. Val, Leu, Ile with their bulky hydrophobic side-chains are stiffer due to steric hindrance, their bulk also tends to make them helix breakers. Hydrophobic side chains are most commonly found in the interior, i. e. buried, of proteins. The aromatic amino acids have a b-methylene to provide some flexibility; they are non-polar, although Tyr has the polar phenol group. Aromatic side-chains tend to pack together at 90°C , rather than side-to-side. Trp has the largest side-chain. Pro is non-polar and has a very rigid side-chain, causing a "kink" in the peptide backbone. Usually Pro breaks a helix, and many turns contain Pro. It usually is found in the more stable trans configuration, but occasionally in the cis configuration. Polar side chains (Ser, Thr, Cys, His, Asn, Gln) have the potential to form H-bonds with the
Read on to learn more about two of these cultures. Inuit The Inuit are the native cultures that continue to live on coastal areas of Arctic tundra in Canada, Alaska (USA), Siberia (Russia), and Greenland. Over this broad area there are many different groups of people. Some share common ancestors, others probably do not, but most have similar ways of living in the Arctic. Inuit traditionally hunted for seals, whales, polar bears, caribou, birds and other animals from the ocean and the tundra. Inuit people invented the kayak and used these small boats to hunt for Arctic marine animals. Because of a great respect for these animals, Inuit have traditional customs that must be followed during a hunt. Inuit myths were inspired by the environment that they lived within including the magical appearance of the aurora in the night sky, the long dark winters, and the icy Arctic Ocean.
