A biologist receives seven new species of live insects from Brazil and is asked to determine their evolutionary relationships. Which method could help the biologist with this task?

Firstly, biologist must look at the similarities in their structural anatomy.

Secondly their embryonic development should be studied to trace the similarities in their development.

Thirdly, to determine the degree of evolutionary similarity and dissimilarity, the biologist should study and compare their DNA sequences.

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.
