Emperor Penguin Research Paper
In Antarctica it can get as cold as -50°C this is because the sun is aimed at a shallow angle towards Antarctica this means that there is not a lot of sunlight that hits Antarctica, the sun that does hit Antarctica is either reflected off the shiny white ice and the heat energy is sent into space or the heat energy from the sun's rays is absorbed by water vapour and dust, the sunlights energy is also spread across a large area therefore there is a large surface area to volume ratio. Emperor penguins have behavioural, physiological and structural adaptations that allow them to adapt to the environment around them.

In the ocean the temperatures reach down to -2°C (the point at which the ocean freezes at), one of the ways that the Emperor penguin's is a layer of blubber (fat). Blubber is a thick layer of fat that protects the emperor penguin's from freezing while in the water. Emperor penguins have waterproof feathers that are overlapped so that air is trapped between the feathers and so that the emperor penguin can glide through the water easier and faster. The emperor penguin's flippers are hard and covered in very short feathers. This allows the emperor penguin to glide through the water, makes chasing their meals and avoiding predators like Leopard seals easier. Emperor penguins have a streamline body this means that it provides less resistance to the flow of water which increases the movement of the emperor penguin and its speed. This is an advantage to the emperor penguin because it means that they can swim faster and have more of a chance catching a meal or getting away from predators. Emperor penguins can dive down to depths of 550 meters and hold their breath for up to 22 minutes. Diving down to these depths could have risks because at 550 meters down means that there is 55-56 Atmospheric pressure on top of the emperor penguin, this means that the emperor penguin has adapted to survive the pressure. One of the ways that the emperor penguin has adapted to the atmospheric pressure is by having heavy thick bones. Having heavy thick bones means that the emperor penguin's bones will not be crushed by the pressure, this is an advantage to the emperor penguin because they can dive down further to reach the bigger meals like squid. This is important because the emperor penguin will get bigger meals that will keep her full in addition to also feed her chick when she returns to land. Emperor penguin's holding their breath for up to 22 minutes means that they can dive down further down and collect larger

    The Fabulous Freebirds Research Paper

    When The Fabulous Freebirds first came to the ring with rock and roll blasting, it was revolutionary. When Vince McMahon got Cindy Lauper and MTV to cross-promote their programming it was groundbreaking. For every hit moment like those in rock and wrestling, there are plenty of flops. The Simon Cowell produced "Slam Jam" can barely be considered music and still somehow managed to hit the UK charts. Looking back, "Rap is Crap" made the otherwise lovable Mr. Perfect Curt Hennig look like an out-of-touch, redneck tool. At WrestleMania XIX, Limp Bizkit got Roman Reigns level boos from the crowd who were generally sick of their repetitive, whiny nu metal.

    Polar Bear Analysis

    Polar bears are extreamly well adapted tohunt their prey under water. Keeping warm is no problem for polar bears infact sometimes polar bears have to lay flat on their stomachs on the ice just to cool of. Polar bears have the thickest fur of any bear species. Their fur has two layers. The first layer, the under coat, is the closest to their body it consists of thick, plush, hair that retains heat. The next layer, the outer layer, is a layer made of "guard hairs" and are not actually hair at all they are hollow tubes. the tubes trap air for insulation andalso reflect a visible wavelengths of light in their hollow air space, which combine to make the fur whiteeven though it is in fact colorless. The white coloring provides camoflauge for the bears allowing them to blend in with there white snowy surroundings. Under their fur polar bears have black skin that absorb the sunlight and under that they have a 4-inch layer of blubber. This blubber keeps polar bears warm in the cold water. Polar bears have fur at he bottom of their feet providing extra warmth and traction to the ice. they are adapted to swim 60 miles without a pause to rest. They have have the ability to reduce their metabolic rate when the food is scarce and again when it's…

The average goose in the wild had lived 30 years and 4 months old. This is an unusual lifespan for a wild bird; the life expectancy for average most wild geese is 12 years. Canada geese (Branta canadensis) are native to Northern America to included Mexico. Canada geese usually spend the winter in southern parts where the weather is cooler. Regardless of the past of the Canada geese have been introduced to habitats worldwide to include much of Europe, Australia, and parts of Asia. Canada geese can be successful to live at nearly all elevations, and the most of the cold region…

    How Humans Have Affected the Antarctic Food Web

    Thinning of the ozone layer will also have a long-term effect on the Antarctic food web. Scientists are speculating that the ultraviolet rays penetrating the waters are the cause of the decline in algal production. Global climate change is another way that humans have affected the Antarctic population. As the temperature of the water has warmed there is less pack ice being formed during the winter months. Pack ice is critical for the survival of the krill because the krill feed from the marine algae. If the waters continue to remain warm the…

    Polar Bear Evolution

    Under the polar bears thick, white fur they have black skin that reflects light of the freezing arctic landscape. Their fur is oily which helps them to be water repellent; the polar bear's solid fur and a remarkably thick layer of fat under its skin protect it against the cold temperatures of the ice .The fat is important when the bear is swimming, because the fur cannot keep the insulating air trapped in it. The hairs are hollow, so the black skin underneath can absorbed light from the UV rays; these genetic traits allow them to have a better chance of survival in temperatures below zero. The polar bear’s fur grows from 5 to 15 cm long. The growth of the fur is the same amount of insulation from the cold that the polar bear receives. The physical features that defined this species include longer neck and head; this trait allowed the polar bears to reach for their prey. During the day polar bears can locate seals from a long distance. The polar bears are patient when it comes to stalking their prey. They flatten their bodies on the icy surface, their forefront feet are under them and only their hind feet provide the force when moving closer. Sometimes they push a small blocks of ice in front of them to camouflage their dark noses, or cover their noses with their white paws to avoid their prey from seeing them. Polar bears spend a lot time in water; the use of the polar bear limbs in…

    The Importance Of An Ice Sheet In Antarctica

    Antarctica consists of mostly frozen ice particles and may very well vary huge chunks of ice burgs. Sea ice keeps the Polar Regions levelheaded and helps adequate global climate. Sea ice has a bright surface; that contains eighty percent of the sunlight that strikes it is revealed back into space. As sea ice melts in the summer, it exposes the dark ocean surface. Instead of reflecting eighty percent of the sunlight, the ocean only absorbs ninety percent of the sunlight. The oceans eventually heat up, and the temperatures rise further.…

    March Of The Penguinss Theme

    March of the Penguins presents perhaps the most basic concept of all, reproduction. The film documents the annual cycle of the Antarctic's emperor penguins and the vast distances they must tolerate in order to survive and repopulate. Just prior to the beginning of winter, packs of penguins crawl up onto the ice and set forth to toddle some 70 miles inland. They then congregate with the females at the same mating grounds that they were raised at. Males and females pair off, introduce each other and perform their ancient mating dance. Once the egg is laid, the female passes it off to the male. She heads back to the ocean to fatten up again, he stays behind and guards the egg in the bitter cold. When the egg hatches, the females come back to the site with full bellies and food for their newly hatched chicks. Now, the males' will in turn to march back to the ocean to feed. This is the cycle that the penguins have endured for millennia.…

    An albatross aloft can be a spectacular sight. These feathered giants have the longest wingspan of any bird—up to 11 feet (3.4 meters)! The wandering albatross is the biggest of some two dozen different species. Albatrosses use their formidable wingspans to ride the ocean winds and sometimes to glide for hours without rest or even a flap of their wings. They also float on the sea's surface, though the position makes them vulnerable to aquatic predators. Albatrosses drink salt water, as do some other sea…
