Discussion and Conclusion:
During Lab 1A, the data suggests what molecules can and cannot diffuse across a selectively permeable membrane. The coloration showed that the Iodine Potassium Iodide was small enough to pass through the pores of the membrane because the color of this indicator moved from within the beaker to in the bag. Water and glucose moved out because water is small enough to pass through the membrane and the glucose tested positive with the Testape inside the beaker. The glucose at the beginning was only in the bag, so it obviously moved out.

When to connect the dots? If each point in the series is obtained from the same source and is dependent on the previous values (. a plot of a baby's weight over the course of a year, or of muscle strength on successive contractions as a muscle fatigues), then the points should be connected by a line in a dot-to-dot fashion. If, however, the series represents independent measurements of a variable to show a trend (. mean price of computer memory over time; a standard curve of optical density vs. solute concentration), then the trend or relationship can be modeled by calculating the best-fit line or curve by regression analysis ( see A Painless Guide to Statistics ) Do not connect the dots when the measurements were made independently.
