The wooly mammoth, Mammuthus Primigenius, was a large animal that can reach heights of four meters. The woolly mammoth though giant ate a diet of grasses, twigs, and leaves. Because the woolly animal was so large it did not have many predators the two main predators were, early human ansesstors and large sabertooth cats. The wooly mammoth species was able to survive through the ice age but became extinct when they could not handle the major climate change. Though they did become extinct scientist look to modern giants for answers, these giants, the Asian and African elephants.
The Wooly Mammoth is built up of eukaryotic cells. These eukaryotic cells have nucleuses and many other organelles. The cells are built up of many organelles. Though the cells have many organelles that are all required to keep everything running, some have very distinctive jobs. One organelle is the cell membrane, the cell membrane supports and protects the contents of the cell which makes it a key organelle for the cells survival. Another organelle is the nucleus,

Wooly mammoths have two distinct genders, male and female. The female is slightly smaller than the male in weight and height. The woolly mammoth has many distinct features that make it such a recognizable prehistoric animal. One of these key features is the woolly mammoth tusks. Woolly mammoth tusks are usually measured between two to three meters but, the largest found tusk was over four meters. The tusks were used for scavenging for food and protection. similarly mammoths also had very long hairs that helped to keep them warm in the cold climates. Wooly mammoths shire size also makes them distinct, woolly mammoths grew to around three meters high at the shoulder. Woolly mammoths had very long trunks with a large upper lip used for grabbing tufts of grass. One last key characteristic that makes a woolly mammoth so distinct is their small ears. Their ears were small to conserve
In this paper Martin is arguing that late quaternary or near time extinctions where caused by human activity or as he calls it “overkill”. Martin recognizes that there have been many forces that have triggered extinctions in the planet on the past but disagrees with the idea that near time extinctions where caused by some commonly believed causes like climate change, disease or nutrient shortage. He argues that the arrival of humans to different continents, islands and the subsequent excessive hunting, the introduction of diseases and other competitors and predators was the cause of extinction of a great number of species “As our species spread to various continents we wiped out their large
The Smilodon, the most recent type of saber tooth cats, went extinct about 10,000 years ago, around the time when Pangea began separating and breaking up. Sabertooth Cats did not go extinct due to lack of prey. However, around 12,000 years ago (end of the late Pleistocene) sabertooth cats, american lions, wooly mammoths and other gigantic creatures considered the “megafauna” went extinct. A die-off called the Quaternary extinction. A popular theory for the extinction is that the changing in climate during the end of the last ice age, human activity, or a combination of both killed off most large
In Sara Gruen’s novel Water for Elephants, the theme of love being a driving force in the characters’ decision making is displayed through the use of characterization and conflict throughout the novel. Jacob’s love for Marlena causes him to make unexpected and often foolish decisions. When Jacob suddenly kissed Marlena, her reaction caused him to realize “‘[he] shouldn’t have done that,’” (Gruen, 2006, p. 153). Jacob was unable to conceal his love for Marlena, which, in turn, caused him to suddenly kiss her. Jacob’s character is extremely love driven, which is demonstrated by his romantic outbursts. Without thinking of the results, Jacob decided to keep Rosie because of his love for her. When Jacob told Marlena they were keeping Rosie, his reasoning was “‘I love that bull.
The grizzly bear trophy hunt is an issue regarding the citizens of Canada who immorally hunt and kill grizzly bears for pride, thrill, and trophy. Many people question whether this is morally acceptable as hunters kill without a conscience. Grizzly bears are vital to Canada’s environment as they are essential to maintaining a healthy ecosystem. As keystone species, they regulate prey, disperse seeds of plants,and aerate soil to maintaining forest health. Due to the vulnerability and over-hunting of grizzly bears, Pacific Wild and many other non-profit organizations, are working to protect wildlife in British Columbia, especially the grizzly bear habitat.
Whales living in captivity become aggravated and have been known to take out anger on themselves by self harming. In the pools they live in, metal bars are placed in between the pools to prevent the killer whales from swimming to another pool. On several occurrences, the whales have attempted to bite and break the metal bars. This leaves the whales with broken teeth and a risk of infection. Infections in killer whales can lead to death in many cases. If a whale gets an infection, they have to be taken out of the pool and placed into another pool by themselves to prevent any problems with other killer whales they live with. In many cases, whales with infections need serious care from whale specialists.
In this period the Earth was very cold and there were multiple glaciers. It was a huge ice age. Scientists say that the reason for the ice age was because of a 100,000-year cycle related to the Earths orbit and shape. Mammals got very big and lived in cold grasslands. These animals were relatives of the elephants. They are mammoths and mastodons. The extinction of these animals was at the same time of the extinction of the ice age.
The most unique feature of the platypus is the soft and pliable bill. The bill surface is perforated with openings that contain nerve endings, which allow the animal to locate food and aid movement under water. These pores contain two types of sensory receptors: mechanoreceptors, which respond to tactile pressure, and electroreceptors, which respond to electric fields. The eyes and ear openings are located behind the bill in a muscular groove, which contracts and closes as the platypus dives (Griffiths, 1998). The nostrils are positioned towards the tip of the bill and are slightly elevated upwards to allow breathing whilst the body is beneath the surface (Figure 1).
Everyone has a family member, friend, or beloved pet so sick you were not sure if they would live or die, and you find out about a new surgery procedure or medicine available to save them. Have you ever wondered where these new surgery procedures or medicines come from? When you think about all the major medical advancements over the last few decades and beyond, it has depended on animal research. As research moves into the future, we need to understand how the body works and how diseases progress. We need to find ways to treat, cure, or prevent disease and disability. The use of animal research is providing us with new technologies and medicines, which are benefiting both humans and animals in treating and extending lives.

Cats and dogs are fun to play with and fun to be around. However, some people go for snakes, birds, or rodents; most people usually prefer a four-legged animal like a cat or dog. Dogs and cats share seldom similarities, but they 're totally different. They have different attitudes, habits, and needs. Wanting love, loyalty, and protection, a dog is a choice. Cats, on the other hand, don 't need attention nor love. Sometimes do we take advantage of our animals because of their size and vulnerability? Beating, improper care, and use of fighting, causes harm to our furry pets. Inflicting pain and making our animals suffer is atrocious. Because our animals can 't speak for themselves, we need to speak for them and stop animal abuse.
Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth
For years studies and observations have been made on the relationship between body size and physical orientation of an animal. In 1847 Carl Bergmann was one of the first to do observations with this phenomenon (Dictionary of Theories 2002). Bergmann noticed that warm-blooded animals living at climates high in latitude are bigger in size than those living in climates of lower latitudes (Dictionary of Theories 2002). Research has shown there is a correlation of surface area to volume in animals that are located in different parts of the globe. Animals living in a cooler climate have a larger volume, but decreased surface area to retain as much body heat as possible. The inverse is true for animals living in warmer regions; these animals have a smaller volume and larger surface area to allow the body to cool efficiently (McNab 1971). Bergmann’s rule has brought valuable insight into the study of character traits and how we identify where animals originated. One example that I came across is with the Andean passerine bird, a study was done in 1991 by G. R. Graves. He noticed the size of ...
The Animal Cell is a little bit different than the Plant Cell for only a couple of reasons. One is how the Plant Cell has a cell wall and the Animal Cell doesn’t. The cell wall protects and gives structure to the cell. Then there is the Nucleus, which serves as a control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the Cytoplasm. This is the watery material lying within the cell between the cell membrane and the nucleus. The Cytoplasm also contains organelles, which have specific functions in the cell metabolism. Then there are the Golgi Bodies, which serve as processing, packaging, and storage for the cell. These organelles package and ship things out. Another parts of the cell, a very important one in fact, are the Lysosomes. These organelles are used to break things down and contain enzymes.
Mammals are vertebrates and, unlike other animals, have 3 middle ear bones (the malleus, incus and stapes), have body hair and provide their young with the milk that females produce in mammary glands, which are modified sweat glands. They are endothermic and produce their body heat internally. Most species of mammals give birth to their living young while some, like the platypus, lay leathery, shelled eggs.
White-tailed deer the most common member of the deer family and are also known as “Virginia Deer”. The first part of the name comes from its most distinctive feature, the 6-11 inch white tail or “flag”. A white-tailed deer averages around 42 inches tall, this deer ranges anywhere from 100 and 300 pounds in weight. The color of the deer's upper body and sides changes with the season, from a normal reddish-brown in summer to a greyish color in winter. Its belly and underside of its tail is completely white along with a white patch on their throat. White-tailed deer shed its fur twice a year, changing from a heavier coat in the winter to a thinner coat in the spring. A fawns coat is very similar, except that it has many white spots all over until about 4 months old. Fawns are born late spring or early summer.
