Based on the information in Table 2, what patterns do you observe? Based on the information in Table 2, the patterns that I observe is that wherever there are fish, there is dissolved oxygen. The more fish there are, the more dissolved oxygen there is. Since fish are living organisms that need oxygen to survive, there is always going to dissolved oxygen in the water when fish are present.
2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. A hypothesis that relates to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water is the more fish that are present, the more dissolved oxygen will be present.
3. What would your experimental approach be to test this hypothesis? My experimental approach to test this hypothesis would be to measure how much dissolved oxygen is found in the water when no fish is present. Then, measure the water with fish in it, increasing by 2 every time. Record the amount of fish and dissolved oxygen in a chart. When about 20 fish is reached, stop recording and put all the data into a line graph. Using a line graph will help see any patterns between dissolved oxygen and number of fish.
4. What are the independent and dependent variables? The independent variable is the number of fish being observed. The dependent variable is the amount of dissolved oxygen found in the water.
5. What would be your control? My control would be recording how much dissolved oxygen is found in the water when there are no fish present.
The Essay on Blood Vessel Oxygen Cells Water
1) To overcome many of the obstacles on the path of any life function, specifically gas exchange, evolution has provided many adaptations. Some of these are the gills fish have developed, some insects ability to diffuse oxygen to individual cells or a moist diffusion barrier in humans. Fish have developed a trait called countercurrent exchange, in which blood passes through vessels in a direction ...
6. What type of graph would be appropriate for this data set? Why? The type of graph that would be appropriate for this data set would be a line graph. A line graph would be appropriate because you would be able to tell if there were any patterns, trends, or relationships in the data or between the number of fish and amount of dissolved oxygen.
7. Graph the data from the table above.
8. Interpret the data from the graph made in Question 7.
