A volumetric pipette has one marked line that indicates a specific volume. Considering polar substances dip downward in a glass volumetric pippette creating a concave meniscus, what is the correct way to read a volumetric pipette to have the most accurate measurement? When the top of the meniscus is at the line When the bottom of the meniscus is at the line When the line is exactly halfway between the top and bottom of the meniscus

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
