Background information Daphnia Magna is an arthropod that can grow up to 5 mm. It is a filter feeder meaning it feeds off of suspended particles in the water. Daphnia can consume particles that range from 1µ to 50µ. The heart of Daphnia is located dorsally meaning it’s located in the back. The heart rate of Daphnia can range due to many variables‚ one being temperature. "At a temperature averaging 20o C its heart rate is about 200 beats per minute."2 As the temperature surrounding the Daphnia

evaporation (net flow of fresh water into ocean); most estuaries are this type. Negative estuary – evaporation exceeds fresh water input. This can happen in tropical lagoons with little freshwater input (salinity 35 ppt. Hypersaline lagoons Indian river lagoon‚ 42 ppt has been recorded. Neutral estuary – freshwater input- evaporation. This system is not used much anymore‚ because a single estuary could go from 1 to 3 to 2 in a year. Classification Based

Lakes: standing bodies of water range from ponds a few square meters in area to lakes covering thousands of square kilometers. Temperature lakes may have a seasonal thermocline; tropical lowland lakes have a thermocline year-round. Salinity‚ oxygen concentration‚ and nutrient content differ greatly among lakes and can vary with season. Wetlands: habitat that is inundates by water at least some of the time and that supports plants adapted to water-saturated soil. Some wetlands are inundated at all

water? Purpose: I want to know why the egg floats in fresh water and not salt water. I want to know if the egg will float in salt water‚ Also this shows why materials float easier in saltwater and sink in freshwater. Research: Since the egg’s density is higher than the density of freshwater the egg will sink. Density is mass per unit volume‚ which means a measure of how much mater is in a certain volume. If you add enough salt the egg will float again. The salt makes the water denser because the

Should the state of Washington allow Icicle Seafoods to establish a net-pen salmon aquaculture operation in the Straits of Juan de Fuca‚ just off the coast near Port Angeles? Decision makers should be mindful and have all the information when deciding on whether to allow the Icicle seafoods to establish a net pen salmon aquaculture operations. I am going to give you some background information regarding the Salmon population in Puget sound/ Strait of Juan de Fuca and net pens‚ to help you make

primary sources that is‚ microorganisms living in Lake residues and freshwater swamps. The increase will surpass the prevalence of carbon dioxide. Its growth has forced scientists to investigate the impact of the increase. It is known that greenhouse gases cause global warming that consequently cause droughts‚ the spread of diseases and changes in the ecosystem among other effects (Reay‚ 2010 p.76). Researchers noted that freshwater microorganism‚ through the process of methanogenesis produces methane
