Base your answer to questions #1 through #3 on the data table below and on your knowledge of biology. The data table shows the concentrations of oxygen in parts per million (ppm) present in freshwater and seawater at various temperatures.
1) Mark an appropriate scale on each labeled axis. (1point)
2) Plot the data for freshwater oxygen concentration on the grid. Surround each point with a small circle and connect the points. (1point)
3) Plot the data for seawater oxygen concentration on the grid. Surround each point with a small triangle and connect the points. (1point)
