Two species of fish have been found together in five different lakes. the larger, bottom-dwelling species feeds on large prey close to shore. a surface-dwelling species feeds on small plankton in open water. dna analysis shows that the two species in each lake are more closely related to each other than they are to any of the other fish species in the lakes. however, they are reproductively isolated. these two species are likely to have arisen due to
a. allopatric speciation.
b. allopolyploidy.
c. sympatric speciation.
d. polyploidy.
e. autopolyploidy.

it would be heredity

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.
