24) Use the information below and your knowledge of biology (huh!) to answer questions 24 and 25:Each student in a biology laboratory received two solutions. One solution was distilled water. The other was a salt solution with a concentration of salts slightly greater than that of the cell. The solutions were labelled X and Y, respectively. The students were instructed to place some fresh-water Protozoans in each of the solutions and to identify the solutions on the basis of their observations. The Protozoans in solution X shrivelled. Those in solution Y swelled up and burst.These results indicate that
