no

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.

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.

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
