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.

Animals will also tend to have shorter legs, tails, and ears, in order to reduce heat loss. Alpine animals also have larger lungs, more blood cells and hemoglobin because of the increase of pressure and lack of oxygen at higher altitudes. This is also true for people who have lived on mountains for a long time, like the Indians of the Andes Mountains in South America and the Sherpas of the Himalayas in Asia. 6. What animals live in Arctic and Antarctica. Arctic-reindeer, polar bear, Arctic fox, narwhal, walrus, seal, ox, moose, orca, and snowy owl Antarctica- blue whale, emperor penguin, weddell seal, octopus, sea star 7. Why is tundra so wet? The warmer weather in summers causes a layer of permafrost, ice that never goes away in the ground, to melt, creating bogs and shallow lakes that don't drain. 8. What is snowline? A snow line is the point above which snow and ice cover the ground throughout the year. The actual snow line may seasonally be significantly lower. 9

Tundra

Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground. The average winter temperature is -28°C, but the average summer temperature is 3-16°C.

Sunflower

The sunflower (Helianthus annuus) is an annual(iga aastane) plant in the family Asteraceae, with a large flower head (inflorescence(õiekobar, õisik, õitseaeg, õidumine)). The stem(tüvi) of the flower can grow up to 3 metres tall, with the flower head reaching 30 cm in diameter. The term "sunflower" is also used to refer(nimetama, viitama, üle andma) to all plants of the genus(perekond, sugu) Helianthus, many of which are perennial(alaline, aastaringne) plants. What is usually called the flower is actually a head (formally(ametlikult) composite(liit-, komposiit- ; korvõieline, komposiit) flower) of numerous flowers (florets) crowded(täistuubitud, tunglev, rahvarohke) together. The outer flowers are the ray florets(pähik (õisiku osa) and can be yellow, maroon, orange, or other colors, and are sterile(steriilne, viljatu). The florets inside the circular head are called disc florets. Sunflower head displaying florets in spirals of 34 and 55 around the outside The florets wi

Cats

AMBER AND RUSSET - LATE COLOUR CHANGE GENES Copyright 2014, Sarah Hartwell The ancestors of the domestic cat were nondescript black/brown striped tabbies. Over the centuries, mutation produced a wide array of colours based on 2 different pigments. Eumelanin gives the blacks, browns and blues while phaeomelanin gives the reds, fawns and creams. A few other genes give further variations on those colours such silvers, colourpoints and solids/selfs. Mutations continue to occur and unexpected colours also turn up due to inbreeding where recessive genes, hidden for generations, start showing up. AMBER AND LIGHT AMBER During the 1990s, some purebred Norwegian Forest Cats in Sweden produced chocolate/lilac and cinnamon/fawn offspring. However, those colours are not found in the purebred Norwegian Forest Cat gene pool. Had the gene pool become polluted by someone, perhaps generations ago, breeding their Norwegian Forest Cat to another breed? Was it a spontaneous mutation? Crossing of those c

The Galapagos islands

Introduction... I read a book abput the Galapagos islands writen by Paul D. Steward. I have devided my presentation in 3 paragraphs: Firstly i will tal about the origins of the islands and the history, secondly about life on the land and in the sea, finaly about conserving the Galapagos. The Galapagos Islands are situated on junctions between several shifting tectonic plates on the equator and about 1000 km off the Pacific coast of Ecuador. They are the product of one of the most volcanically active regions on our planet, a hot spot is situated directly beneath the islands and also It is the point where major ocean currents meet. These circumstances combine to make an area that truly is like no other place on earth. Galapagos is comprised of 13 major islands, more than 120 smaller islets and rocks, and the surrounding ocean. The total land mass is almost 8,000 sq. km. Highest peak is Wolf Volcano reaching 1707m. The present islands are all younger than 4 million years and were formed

The Giant Eland

The Giant Eland The Giant Eland (Taurotragus derbianus also known as the Lord Derby Eland) is an open forest savannah antelope. It is found in Central African Republic, Sudan, Cameroon and Senegal. There are two subspecies: the endangered T. d. derbianus, found in Senegal's Niokolo-Koba National Park, and the low risk T. d. gigas, found in Central Africa. Characteristics Giant Eland are typically between 220-290 cm (7.3-9.6 ft) in length, stand approximately 150 to 175 cm (4.9 to 5.7 ft) at the shoulder, and weigh 440-900 kg (968- 1,980 lb). Despite its common name, it is of very similar size to the Common Eland. The smooth coat is reddish- brown to chestnut, usually darker in males than females, with several well-defined vertical white stripes on the torso. A crest of short black hair extends down the neck to the middle of the back, and is especially prominent on the shoulders. The slender legs are slightly lighter on their inner surfaces, with black and white markings just above t
