- The following table gives the total amounts of water and salt in the oceans and the total influx of water and salt from rivers each year. Use this information to calculate the residence time in the world ocean of both water and salt.A) What is the independent variable? What is the dependent variable? B)In what type of environment would you most likely find Fish Species 1 In what type of environment would you most likely find Fish Species 2 C)How much oxygen is consumed by Fish Species 1 when the salinity is 10 ppt? Fish Species 2 will consume 6 mg/min of oxygen at what salinityWhat is a benefit of uniform dispersion? decreased competition increased resources easier reproduction increased competition
- Identify the three main patterns of dispersion observed in natureWhich of the following groups would be the most likely to exhibit uniform dispersion? a red squirrels, who actively defend territories b cattails, which grow primarily at edges of lakes and streams c dwarf mistletoes, which only live on a particular species of forest tree d moths, in a city at night e lake trout, which seek out cold, deep water high in dissolved oxygenMake a List including the short-term and long-term impacts(negative and positive) on construction storage and recharge dams in a scientific table Each is rated(slow, moderate, high)

What patterns do you observe based on the information in Table 4? 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. 3. What would your experimental approach be to test this hypothesis? 4. What would be the independent and dependent variables? 5. What would be your control? 1)Table 1: The density of dippers (Cinclus cinclus) per km of upper stream length in 18 rivers across Great Britain: the pH of stream water also shown as too their individual territory lengths (km). Data collected with the assistance of the British Trust for Ornithology in May 2001. Draw a graph showing the relationship between dipper density and stream pH. Label the axes and provide a figure legend.Table 1: The density of dippers (Cinclus cinclus) per km of upper stream length in 18 rivers across Great Britain: the pH of stream water also shown as too their individual territory lengths (km).
