Name:Neko Science Fair Paper Daphnia Magna are small water fleas that are native to Minnesota. They are an indicator of good water quality ( Science buddies,2010 ). Daphnia Magna are small enough to be eaten by dragonflies, and are food for many small to medium sized fish. The reason that we should be paying attention to Daphnia Magna is because of pollution in our lakes. This pollution can affect a lot of actions that we do in our daily lives.…
Therefore, evaluation of negative impacts of pollutants on living organisms in the form of toxicity testing is routinely used to produce baseline data for environmental hazard and risk assessment of chemicals.94 Daphnia magna, an important link in the food chain of aquatic ecosystem, which is highly sensitive to toxic substances has been used to understand the toxic effect of waste effluent.94 To date, some explicit studies to understand effects of multiple stressors on aquatic ecosystem have been reported that are hints of how mange the freshwater in the wake of multiple stressors.95–98 The current project helps understand and compare toxicity of different stage of wastewater from influent to effluent in their intact and unaltered form.…
Tasmanian Devils are carnivorous marsupials that have marveled mankind with its intense strength for its small size. This one foot tall mammal is probably one of the toughest in the world. These nocturnal animals live primarily in Tasmania and Australia. These snarling creatures have a life span average of about five years. In those five years the Tasmanian Devil accomplishes all nine processes of life.…
evolutionary trend that causes this increase because for many species, having a bigger body size results in an increase in fitness. However, there are several changes that occurred in the Equidae family that are as significant to evolution as body size. The discovery of Equidae fossils worldwide has provided excellent evidence of the evolution which has affected many characteristics of the family. An example of one or the most notable alternations seen between the first ancestor, the Eohippus of the Eocene period, and modern Equus can been seen in the feet and limbs of each and through the many related species also in the family tree.…
Sloths are under Xenanrthrans, and Xenarthra includes the armadillos and American anteaters. Sloths and anteater are more closely related to each other rather then armadillos. Sloths was introduced into the world 37 million years ago. Sloths are known to be the most diverse group of this family. Species that are under Choleopus is known as the two toed sloth, and the relationship between the modern sloth genera.…
The exhibit Evolving Planet showed how one period led to another. It gives evidence of changes and adaptionsThrough each time a person can see that there were similarities between animals and how they adapted to fit into that period. In the Quaternary Period during the Ice Age I saw what was called the Giant Ground Sloth which is a much bigger version of sloth that we see today. They evolved in the South American grasslands and then later migrated to North America. They could survive cooler climates of their large size and good insulation.…
Narwhals are, From many perspectives, the dominant form of life on earth. Narwhals continue to dictate and control many of the ecosystems the inhabit. Narwhals have undergone an interesting history as they evolved from their Bohaskia monodontioides ancestor. They have a long horn that come out of their head. They are like the jedis of the sea.…
Alix Lippincott Mr. Day Biology B4 May 15, 2016 The Evolution of the Gray wolf Every species has an evolution, the gray wolf is no different. They belong to the “Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Carnivora, Family: Canidae, Subfamily: Caninae, Genus: Canis and Species Lupus.” The gray wolf didn't start as a gray wolf it was originally a different animal that adapted overtime to become a gray wolf.…
Dingoes have a tail, which means that they are deuterostomes. Dingoes fall under mammaalia in the Class category because like all mammals, dingoes have hair, three middle ear bones, mammary glands, and neocortex. Since dingoes have mammary glands, they are able to produce milk and feed their offspring. The arrangement of the dingo’s teeth proves that it belongs in the Carnivora group in the Order category. All animals in the Carnivora group have a similar layout of their teeth.…
This article, written by Londa Schiebinger “Why Mammals are Called Mammals,” points out the main argument that mammals are extremely similar to humans especially females in this world because they share common characteristics of women such as producing milk, and having hair and mainly why they are called “mammals” instead of something else. Additionally, on how female characteristics are different from men and how their is a sexual division within. It is then said during the time around 1766 historians struggled to classify these animals by name and whether the name thought of was better suited. According to the article, words such as Pilosa, Aurecaviga, Quadrupedia, Vivipara, Terrestria, and Trichozoologia were used to identifty mammals but…
There is only four species identified within the genus. The Anhinga is related to the darter family. The Anhinga falls under the kingdom Animalia, (del Hoyo, et al., 1992; Hennemann, 1985; Isenring, 1997). The Anhinga has been seen in a variety of climates from tropical to subtropical, which areas are known to have warm weather.…

Prosimian Their primary native land for Prosimian lemurs is Madagascar. They are…

Another group that is classified by the order Carnivora are the polar bears and sea otters. These animals have a more primitive structure of a paw or padded foot, and they are marginally aquatic because they can spend some time in water, but most of their time is spent on land. Many of these animals go into the water to eat, and they play a large role in maintaining marine ecosystems in regulating populations of prey. There is no significant fossil record because these animals are thought to be recent entries into the aquatic environment (Uhen, 2007). Both polar bears and sea otters are covered in fur like most mammals, but they have adapted an oilier fur that is practically waterproof (Reidenberg, 2007).…
The first mammals evolved from mammal-like reptiles at the end of the triassic period. Therapsids, or mammal-like reptiles, is an order of reptiles that lived in the Permian and Triassic Periods before going extinct in the mid Jurassic Period. It is difficult for scientist to determine when the divide between therapsids and mammals occurred. Early mammals had small, mouselike forms. Very few were large, because dinosaurs were the unquestioned dominant land animals on earth.…
