Rattus Norvegicus is native to northern China but found its way to Eastern Europe by the early 18th century. When they lived in Asia, they used to be found in the forest and bushy areas, but now are found in sewers, garbage dumps, and basements. Norway rats can eat ⅓ of their body weight in a day, which proves that they are big eaters. They are omnivores which means that it eats both animals and plants. Some animals that it eats are chicks, fish, eggs, birds, mice, and small lizards. Some plants that they eat include are, leaves, bark, fruit, nectar, and flowers. They can also eat spoiled, uneaten food, thrown away by humans mainly in metropolitan areas. They can eat dead animals and can skillfully catch fish and mice. These rats are kept
The sabertooth cat, also known by its scientific name Smilodon Fatalis, is considered a true form fossil. A fossil is considered a true form fossil when scientists recover fossils of the actual animal or animal part. These bones were oftentimes subjected to physical processes while still on the surface. These processes include heat, cold, wind and rain.
This invasive species originates from Southeast Asia. This mosquito has made its way to Africa, the Middle East, Europe and North and South America as an invasive species. The Asian Tiger Mosquito was introduced into the United States accidentally from tires imported from Asia. The islands of Torres Straight have numerous reports of this mosquito also. This invasive species was introduced into the United States, probably Houston, Texas, from Japan in 1985. The constant trade of used tires throughout the U.S. allowed the Asian Tiger Mosquito to disperse across America.
It lives its whole life above the northern tree line in the Arctic tundra, roaming across North America and Greenland but not extending into mainland Europe or Asia.

In criminology there are numerous theories as to the causes of different types of crime. These theories are extremely important in the continuous debate of the ways in which crime should be managed and prevented. Many theories have surfaced over the years. These theories continue to be explored individually and in combination, as criminologists search for the best solutions in ultimately reducing types and levels of crime. These theories include rational choice theory, social learning theory, and biology amongst many others. In this case study strain theory will be used to describe the reasons behind the white collar crimes of Charles Ponzi.
If puffins are disturbed by humans they will leave their nests and will not come back. This has led to the extinction of puffin colonies in parts of the European coastline.

States and southern Canada. In the west, the species was found from Mexico to California.
The first step was to obtain the White Rat and to tie it in the supine position, anterior surface facing up in side the dissection pan. To tie the animal, we used butcher’s twine and secured the front and hinds legs using a “lasso” technique, careful not touch the sharp claws. To make the first insicion I had to locate the Xifoid Process of the rat (distal aspect of the sternum). Once I had located the Xifoid Process, I had to use forceps to pull the skin of the animal’s abdomen up and use the scissors to cut. The first incision is made from stem to sternum, cutting through the errectos abdomen muscle down to the groin. The second incision ion is perpendicular to the first below the diaphragm. Because of this technique we were able to open the abdominal cavity first. The third and forth incisions were made bilaterally above the legs. The last two incisions were made in upside down “V” shape on the collarbone, to expose the thoracic cavity. This dissection was both sharp, because of the use of the scissors and scapel and blunt because of the use of the probe and forceps to move organs and skin to expose other organs not yet identified.
They sleep during daytime and more so in the winter when they live off stored body fat. As very curious and highly adaptable animals, raccoons can be encountered in many different ecosystems. Their homes called dens are typically found in caves, trees, barns or abandoned homes and vehicles. Raccoons are pest species known for their mischievous nature especially when they are foraging for food in highly populated areas. These not very social mammals prefer to live in attics, beneath porches or in the chimneys. The first signs of raccoons outside the house are damaged lawns and crops, raided trash cans and poop in the swimming pool. Once inside the attic, they make lots of noise and mess by tearing off insulation paper and leaving a crazy amount of droppings. Raccoons are known for stealing pet food and their presence can alarm dogs and other household pets. These and many other reasons makes raccoons a nuisance animals. Naturally, people wish to have them trapped and removed from their
What its eating habits are: Like all members of the cat family, tigers are carnivores. The Siberian tiger hunts a wide range of prey, including small mammals, deer, water buffalo, wild pigs, and birds. Tigers ambush their prey, often camouflaging themselves and observing their intended victims for long periods of time. Siberian tigers are strong animals, able to tackle large animals almost twice their size, and render the victim helpless by inflicting a series of deadly bites into the animal's spine or throat. This semi-nocturnal animals covers 6-12 miles each night in search of food.
A rat civilization was discovered today, the first time a civilization created by an animal other than a human was found. GRNN Reporter Gabe Rich, the discoverer of this breakthrough, has more: “I was taking a walk to a story I heard about in Thorn Valley Nature Reserve, and stumbled upon some rats with a rat-sized plow. They were in a field where it looked like they were about to plant some crops. I captured one, but the rest instantly fled. I said to myself, ‘At least I got one.’ It turned out these were no ordinary rats. They had modified DNA. I returned the one as soon as I could, which was a few hours. I am still stunned, as I thought only humans were capable of making, well, civilizations.” Dr. Robert Schultz, the mastermind behind NIMH
Rats are undesirable creatures that have been the symbol of death, pestilence, and disease. Rats can cause billions of dollars in damage and can start fires, spread serious diseases, and multiply rapidly to infest homes, according to the article Top Ten Fascinating Facts About Rats. Additionally, the inundation of rats in a home can cause panic and mass hysteria, with residents calling pest control companies and law enforcement as soon as they see a rat, as expressed by John Davidson in Floods See Rat Population Explosion . The trouble that the rats cause has been an issue for a very long time. The flood of rats that invade a home is believed to be caused by an increases in food sources near populated areas, and decreases in predators and dry
“One day a hare was bragging about how fast he could run. He bragged and bragged and even laughed at the tortoise, who was so slow. The tortoise stretched his long neck out and challenged the hare to a race, which, of course made the hare laugh.” (Stevens 6) This quote is an important part to the beginning to the book, because that is when the tortoise got so sick of hare teasing him, that he challenged him to the race. While everyone has met a “Hare” in their lives, it is how you handle the situation that makes you grow as a person and become who you are. That is why the Tortoise and the Hare should be on the CBC home library list, because of the positive relationships between the characters, visual images and lessons learned.
