That’s the answer hope it helps!!!
The correct answer is B). The potato cells lost water to the surroundings.
The salt water solution is hypertonic as compared to cell of a potato slice. In other words cells of potato slice is hypotonic to salt solution. Water always moves from hypotonic to hypertonic solution if they separated by semipermeable membrane. Thus, when potato slice is dipped into salt water, ex-osmosis that is water will move out of the potato slice into the salt solution. As a result into shrinking of potato slice.

C) 1,3,4
Explanation:
Some aphids make black walnut trees their habitat in the forest and only prefer to mate with aphids who have the same habitat. This is an example of reproductive isolation since these aphids now have different mating preferences and hence are isolated from rest of the aphids. The isolation occurred on the basis of difference in habitats so it is also an example of habitat isolation. Since the mating is prevented all together it is also an example of prezygotic barrier i.e. formation of zygote is inhibited. However, it is not an example of allopatric speciation since the aphids are not separated geographically from each other. They are present in the same area but have different habitat preference. Hence, option C is correct answer.
