(FRQ 2) The following experiment was designed to test whether different concentration gradients affect the rate of diffusion. In this experiment, four solutions (0% NaCl, 1% NaCl, 5% NaCl, and 10% NaCl) were tested under identical conditions. 15 milliliter of 0% NaCl were put into a bag formed of dialysis tubing that is permeable to Na+, and Cl-, and water. The same was done for each NaCl solution. Each bag was submerged in a separate beaker containing 300mL of distilled water. The concentration of NaCl in mg/L in the water outside each bag was measured at 40 second intervals. The result from the 5% bag are shown in the table below. Show
TIME (Sec). NaCl (mg/L) a. On the axes provided, graph the data for the 5% NaCl solution (3pts) Which of the following best explains the difference in water potential between certain solutions and the grapes?Based on Table 1, which of the following best explains the difference in water potential between certain solutions and the grapes? - NaCl and tap water have a lower water potential because these two solutions caused the grape to gain water.
Which of the following best explains the connection between energy growth and the maintenance of an ordered system in the experiment?Which of the following best explains the connection between energy, growth, and the maintenance of an ordered system in the experiment? Energy input from light is required for the grass to grow and maintain an ordered structure.
Which of the following best explains how higher concentrations of nitrogen and phosphorus contribute to eutrophication?Which of the following best explains how higher concentrations of nitrogen and phosphorus contribute to eutrophication? Algae require nitrogen and phosphorus to build macromolecules, so higher concentrations of these nutrients can result in algal blooms.
Which of the following best describes the scientist findings concerning the density of symbionts presented in Figure 2?Which of the following best describes the scientists' findings concerning the density of symbionts presented in Figure 2 ? The symbiont density at 32°C was different from the density at 27°C on days 5 and 10 of the experiment.
