Biotic component

Environment is the term used for defining our surroundings which may include the biotic and abiotic components that are present around us. Biotic components include the microbes, plants and animals and abiotics are soil, water and air [1]. Biotechnology is the integration of technology and natural sciences by utilizing organisms and cells, to produce knowledge, services and products [2]. Environmental biotechnology refers to the application of biotechnology which is used for finding a way to…

identification of the ecological traits that increase extinction risk” (Hobbs et all, 2010). The study focused on pygmy angelfish, but also the fish’s use of habitat, resources, and diet. They researchers found multiple risk factors and determined three components, small range size, low abundance, and specialization that make a fish rare and at risk for extinction. Small range size, which meant a smaller habitat which is more at risk than a large range and distribution. Low abundance of fish…

Land, according to Rossiter (1996), is defined as the area of the earth’s surface characterised by atmosphere, soil, underlying geology, hydrology and the biotic components such as plants and animals. These attributes bring into play a significant influence on the present and future uses of the land by us humans. The turned focus to land for the sourcing out of food, extraction of natural resources and as a source of income for individuals, has been a norm for years. Decisions on land use have…

to an ever increasing importance of proper management. Managers being those that bring people, parts, and procedures together in concert to accomplish some stated goal. (Angus, Gunderson and Cullinane) Of course the corresponding balance of these components, is highly dependent on the field of work the manager. For example, with the surge in the global economy and its health profile, the value of using technology to assess biological data has increased. (James) Most of these tools,…

of the cell fractionation protocol was to separate P. aeruginosa into four cellular components while maintaining the enzyme activity within each of the four fractions. The first step in fractionation is commonly centrifugation as it separates the components based on size, meaning that after the initial centrifugation, the pellet will contain whole cells, and the supernatant will contain the extracellular component (Alberts et al., 2002). The sample we used was spun down and the supernatant was…

Introduction: The world is urbanizing rapidly; the present population living in urban areas is 54%. The more urban an area, the more concretized it is. Urban areas are quite warmer than the rural counterpart, the natural ecosystems are being replaced by buildings and other structures. There is significant temperature differences between city centers and their surrounding countryside and surface temperatures can be much greater in high density suburbs compared to low-density suburbs; the reason…

competitive edge throughout all time periods. Hypothesis 3: Ecological Innovation of the Angiosperm Because abiotic factors often limit angiosperm dominance (Bond, 1989), an intuitive idea is that acquisition of ecological innovations (in terms of biotic interactions) have allowed for supreme angiosperm competition. Three further hypotheses are often outlined in the literature, concentrating on herbivory, reproduction and symbioses.…

crustaceans that contain chitin as a cell wall component, the major role of chitinases appears to be in modification of chitin. Chitinases are also considered to have a role in defense or in enhancing competitiveness in higher plants and animals that do not contain chitin. Bacterial chitinases are mainly involved in degrading chitin to provide carbon and nitrogen nutrition to the cells (Patil et al. 2000). In plants, chitinases have been implicated both in biotic and abiotic stress responses as…

Take the “forearms” of humans, cats, whales and bats for example. Each one has a humerus, radius, ulna, carpals and phalanges, but the structure serves a different purpose for each animal (Evidence of Evolution). Vestigial structures are physical components that are either useless or do not serve the same use as they once did. Vestigial structures do not have to be nonfunctional in order to be considered vestigial; they may “retain lesser functions or develop minor new ones, but nevertheless be…
