Where sister chromatids are attached. when nuclear material is duplicated. a groove at the cell surface located between dividing animal cells. a protein structure attached to the centromere. fusion of an egg with more than one sperm. chromosomes that have the same set of genes, one from the mother and one from the father. microtubule organizing center. a membrane structure located between dividing plant cells. a cell with two nuclei. a microtubule structure in animal centrosomes. reciprocal exchange of genetic material between non-sister chromatids

the correct answer is 2 and 4

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.
