Thorn apple is a plant in the nightshade family for which purple flowers are dominant to white. When a particular purple-flowered thorn apple is self-fertilized, 60 purple-flowered and 23 white-flowered progeny are produced. What proportion of the purple-flowered progeny will breed true

answer: node would be introduced.   is the correct

explanation:

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.
