...Marine Biomes Shonda Morton October 20, 2013 SCI/230 Paula Roberts A marine biome is a large aquatic zone that takes up almost 75% of Earth’s surface, has a salt concentration around 3%, and is distinguished from other biomes by its physical environment. According to Campbell Essential Biology with Physiology, (2010), the habitats of a marine biome varies depending on the level of the sea that it exists (pp.382). The layers or “zones” that make up the marine biome consist of the pelagic realm, the intertidal zone, the photic zone, the aphotic zone, and the benthic realm. The pelagic realm is the part of the marine biome that includes all open water. (Dickey, Reece, & Simon, 2010) explains “the intertidal zone is the part where the ocean surface meets land, or fresh water (pp.383).” The level of the marine biome is home to sedentary organisms such as algae, mussels, and barnacles. The photic zone was named mainly because of the fact that light is available for photosynthesis, and known as the upper or shallow layer of the marine biome. In Campbell Essential Biology with Physiology, (2010), the aphotic zone is the layer of the marine biome where the light levels are too low to support photosynthesis (pp.380). The benthic realm which exists in all aquatic biomes is the area of the seafloor, made up of sand, and organic and inorganic sediments. There are many organisms that exist in a marine biome, and each one exists at different levels...

Write a 100-word summary explaining how that media piece supports that statement and include reference citations. 1. Find a media piece—article, video, presentation, song, or other—related to the scientific method, creating hypotheses, or designing experiments. Include the link or reference citation for the piece and describe how it helped you better understand how the scientific method is used to create hypotheses and experiments. * * “The Scientific Method Video,” is a unique way to present the scientific method by using rap to emphasize the important points. This includes that the scientific method begins with a question based on an observation, and then a hypothesis and prediction are made, experiments are conducted (which need to be reliable, include a variable and a control), and lastly findings are reported. It has been a long time since I have gone over the basics of the scientific method. This video helped me review what I find so fundamental and second nature. Also, I think it is helpful to note that as the textbook states, “These steps guide scientific investigation, but working scientist typically do not follow them rigidly.” This video is an interesting tool to review the scientific method and how it is viewed by the student rappers.

...Genetic drift is simple change. Two different genetic drifts that can change the size of a population are the bottleneck effect and the founder effect (Campbell, Reece and Simon, 2004). The bottleneck effect occurs during drastic changes in an alleles population causing the population to have some alleles that may be underrepresented or eliminated completely (Campbell, Reece and Simon, 2004). Chance may affect the alleles population for generations until the population will become large enough to allow sampling errors to be considered insignificant (Campbell, Reece and Simon, 2004). Genetic drift in a new colony is called the founder effect (Campbell, Reece and Simon, 2004). It is likely to occur when a few individuals colonize an isolated area (Campbell, Reece and Simon, 2004). When a colony migrates away from a larger population its gene pool becomes least representative of the larger colony it migrated from (Campbell, Reece and Simon, 2004). Gene flow is the genetic exchange of another population (Campbell, Reece and Simon, 2004). This occurs when fertile individuals or gametes migrate between populations (Campbell, Reece and Simon, 2004). An example of gene flow would be an Asian woman who conceived a child for an African man. Their baby has Asian and African genes. Gene flow can reduce genetic differences between populations (Campbell, Reece and Simon, 2004). If various...

...Introduction The Daphnia magna, more commonly known as the water flea, is a tiny freshwater crustacean. Its clear exoskeleton and jointed appendages point to its classification as an arthropod. This is further evidenced by the location of its heart—the dorsal region. The Daphnia magna’s importance in the aquatic food chain can be attributed to its essential place in the diet of young and adult fish (Elbert, 2005). The Daphnia magna belongs to Class Branchiopoda, which are free-floating crustaceans that. It is also, more specifically, a member of Genus Daphnia (Ebert, 2005). Branchiopods always have flattened, partially leaf-like, legs. As a branchiopod, the Daphnia magna belongs to the Order Cladocera, which is protected by a calcified...

...‘Not only do Prokaryotes have a wide range of metabolic activities crucial for maintaining the biosphere, they also exert significant impacts on human life’ discuss this statement fully using named examples. Prokaryotes are unicellular microorganisms without a nucleus; they are divided into two groups’ Eubacteria and Archaebacteria. These microorganisms are very small and invisible and are known as the most dominant species on the earth’s biosphere as they are found almost everywhere on earth, they are predominately, found in our body’s immune system, and they are mainly responsible for the decomposition of dead matter which in return benefits both plants and animals. They are found in the air that we breathe, in the food that we eat, in deep seas, in cold and hot temperatures, sea corals, in salt water, fertile soils and in short, they are so diverse in their form of habitation and adaptation, as different types of bacteria adapt to different types of environments in different forms of life. However, bacteria are grouped according to their uniqueness, features, structure, functions, and contribution to human life. Prokaryotes are so beneficial to us because they act as defences to protect us from various diseases. The essay will examine the significant impact of prokaryotes to human life. The word bacteria may be frightening to most of us; in many cases it is often associated with many negative and harmful aspects such as infectious diseases, dental decay, mould and...

...(focus on 36.4, 36.5) in the textbook. * Review recent information on climate change at this website http://www.epa.gov/climatechange/science/stateofknowledge.html Introduction The current state of the biosphere shows unsettling trends. There is a need to meet these challenges, pursue more knowledge, and work as individuals and as a society toward long-term sustainability. Recent research has sent a message that global warming may not be a hypothetical threat, but a current issue warranting immediate action (Krogh, 2009). Global Warming There is a steady rise in carbon dioxide in the atmosphere. It is estimated that the average carbon dioxide concentration in the atmosphere has increased approximately 17% in the past 45 years (Campbell, Reece, & Simon, 2007). It is estimated that 20% of the excess carbon dioxide released into the atmosphere can be attributed to the burning of trees after deforestation. The burning of fossil fuel accounts for another 70-80% of carbon dioxide released into the atmosphere. Global temperatures are concurrently on the rise. Carbon dioxide lets radiation through the atmosphere, but retains some of the heat it generates (greenhouse effect). When carbon dioxide increases in the atmosphere, this greenhouse effect is enhanced, and too much heat from the sun is retained in the atmosphere. Some scientists, therefore, believe that elevated atmospheric carbon dioxide levels are responsible for global warming. Increased temperatures, in turn, may...

...dioxide, or CO2. This is similar to the process that the human body goes through. O2 is inhaled. O2 is carried to cells where it is used in cellular respiration. Carbon dioxide, which is a waste product of cellular respiration, is diffused from the cells and delivered to the blood and goes to the lungs where it is exhaled (Campbell). Cellular respiration is considered a very important process in cells. It protects the cell from harmful increases in temperature as well as provides the cell with a pathway of transferring energy in a controlled environment. The goal of cellular respiration is to break down carbohydrates into glucose, and use the glucose to produce ATP energy. Cellular respiration is made up of one glucose molecule which is added to six oxygen molecules. This equates to six carbon dioxide molecules, six water molecules, and 36-38 molecules of ATP. Cellular respiration is very important to the life of cells. It a constant process used by organisms. The organisms use the sugars in food to produce enough energy to perform all the necessary actions of living creatures (Taylor 2002). Reference Essential Biology with Physiology, second edition.

...Tittle: Useful medicinal compounds derived from animals In modern medication, monoclonal antibody has been used to treat various kinds of disease. For cancer therapy, monoclonal antibody is extremely success. Monoclonal antibody, an immune protein with specific binding site and purified from mouse, can bind with target protein (Campbell NA, 1996). Such as: Specific antigen, growth factor and so on. As tumor cell always avoid immune system and even try to suppress the immune response, they always avoid immune defense. However, if monoclonal antibody is presented, they will bind with the target protein and immune system can recognize. Finally, immune response will be triggered. Tumor cell can be killed by B-cell or Phagocyte. Over a hundred years ago, target drug idea has been proposed. If a drug can be delivery to the target site precisely, the adverse effect of the drug can be minimized. “Delivery the drug to the target site” became a challenge the scientist. In the 1970s, B-cell has been discovered and played essential role (Biotech Resources, 1995-7). Anyways, as the technology, antibody cannot be cloned directly. For this reason, mouse antibody is used. In the beginning, some antigen was injected into the mouse and induced B-cell proliferation. Then, purified the antibody from the mouse. Compare with traditional drug, monoclonal antibody has a relatively low adverse effect. However, as murine monoclonal antibody is not a human protein. It only has a short half- life...

... Describe each stage of the flow of information starting with DNA and ending with a trait. * A sequential set of nucleotides in the DNA are transcribed into a molecule of RNA in the cell’s nucleus. Translation of the RNA into a specific amino acid sequence of a protein occurs after the RNA travels to the cytoplasm. “The molecular “chain of command” is from DNA in the nucleus to RNA to protein synthesis in the cytoplasm. The two main stages are transcription, the transfer of genetic information from DNA into an RNA molecule, and translation, the transfer of the information from RNA into a protein,” (Simon, Reece, & Dickey, 2010, p. 178). * References Simon, E.J., Reece, J.B., & Dickey, J.L., (2010).

...Structural proteins make up the structure of an organism and the enzymes catalyze the metabolic activities. Protein is not built by a gene, but it gives the instructions to do so in the form of RNA, which programs the synthesis of the protein. 3. Describe each stage of the flow of information starting with DNA and ending with a trait. Genes are what carry our traits thought generations and our genes are made up of DNA, but the genes act as an instructions manual for producing functioning molecules like RNA and protein, which preforms chemical reactions in our bodies. Proteins do a number of other things; they give the body its main materials for forming cells and structural components. Reference: Campbell Essential Biology with Physiology, Third...
