Introduced species

because natural selection is the process of which the environment favor the species with favorable traits that will help them survive. Scientists believes that at some point all living beings were one single cell, but throughout years it all developed into animals and humans. In the other hand, religious people, in this case Christians, believe a Superior Being created humanity and other living…

1 Sternberg museum Sternberg natural history museum is located at the Fort Hays State University, Kansas in the United States (US). Its exhibits are permanent on the walls; they includes fossils collected mostly in the western US and all over Kansas. The museum also has exhibits of minerals and videos that explain the museum history; and its famous ‘fish within a fish’ fossil collection history included. 2 Exposure to Formaldehyde Formaldehyde (FA) is a gas that is flammable, colourless and has…

is the variety of life. Most of the people recognize biodiversity by species but biodiversity is more than just species. A species is a group of living organism that can interbreed for example white-tailed deer, blue whales, and bacteria that you cannot even see with your eyes. Species is only one part of biodiversity. Biodiversity can be studied on many levels and at the highest level you can look at all the different species in earth. Biodiversity occurs at multiple scales of ecological…

chordates are of Cambrian age. All chordates are deuterosomes, and their organs are suspended in the mesentery tissue between the endoderm tissue of the digestive tract (alimentary canal) and the ectoderm tissue on the surface. There are about 45,000 species of chordates. The smallest chordates (e.g. some of the tunicates and gobioid fishes) reach a length of about 1 cm. The largest animals that have ever…

Why is biodiversity important to an ecosystem? Why is it so important that we have different species of animals living together? It is extremely important for different species to be living together, because they all rely on one another for survival. Including us humans, we rely on other species to survive. We don’t just rely on other species for survival, but evolution has driven us to evolve to adapt and live longer. In an ecosystem, there are habitats. In a habitat, there are populations…

Introduction: In this experiment I am going to investigate a factor that affects simple animal behaviour. The animal I will be using in the experiment is woodlice. Woodlice are simple animals which like to stay in dark and damp areas. If they are not in an area they like they attempt to find the best habitat for them and they will not stop until they do so. Woodlice have simple reflex behaviours to survive. One reflex behaviour is a taxis and this is when the animal moves towards or away from a…

Fish have a unique position with respect to their taxonomic and phylogenic status among vertebrates and occupy an important place in vertebrate’s genealogy. Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary (1 – 2 ºC) as ambient temperatures change. Majority of siluroid fish are economically important for human consumption. Protein and vitamins content in fish flesh varies from high to moderate and make it as rich source of protein diet. Fishes of siluroid…

long enough to transfer to the pocket of the mother. Their lifespan remains strangely short compared to an animal having the same size. An opossum life usually lasts for an average of three years. Habitat There are greater than 60 diverse opossum species, often known as possums. The highly distinguished is the common or Virginia opossum, the solitary marsupial found within Canada and America. Usually nomadic and solitary, opossums stay in an area provided that water and food are available…

The circadian clock regulate the biology and behavior of a living organism throughout a day (about 24 hours). It can be affected by external factors such as daylight or darkness of the environment. The circadian system can modify the behavior and physiological functions to adapt the environment. For mammals, the suprachiasmatic nucleus (SCN) are the central circadian clock of our body, which is located in the hypothalamus. Meanwhile, there are peripheral circadian clocks which located in most…

Earth is Unique, but is it Really One of a Kind? Earth is such a beautiful planet. With all of its’ oceans, plants, animals and land. The variety of life on Earth is what makes it so special. Actually, the fact that Earth has life at all already makes it unique! Earth is the only known planet that can support life (for now at least). Astronomers have been studying deep space looking for another planet with any life at all, but the technology isn’t advanced enough to know whether or not they have…
