Potato strips were weighed and then soaked in different salt solutions (0%, 0.9%, and 5% NaCl). After 75 minutes the potato strips were dried and weighed, and the percent change in weight was calculated for each Based on the graph, which salt solution was hypertonic to the potato strips? Which variable is the independent variable in this experiment? The cells in the image are displaying plasmolysis. What type of solution must the cells have been placed into? hypotonic solution hypertonic solution isotonic solution
Four eggs are stripped of the shell and weighed. Each egg is put into a solution with a different concentration of salt measured in molarity (M). After 8 hours of soaking, the eggs are weighed again and the percent weight change was calculated and graphed (shown below). Egg Graph 15 10 2.5 3.5 3 -10 -15 -20 Solution Salt Concentration (M) 1.
