To measure the volume of the starch-water mixture in the dialysis bag, the students should have used a
(1) meterstick (3) graduated cylinder
(2) triple-beam balance (4) test tube
The answer is 3) graduated cylinder. A measuring stick to measure depth would not have worked as the overall volume of the beaker containing the </span>dialysis bag would not have changed. A test tube would generally have insufficient volume to measure the volume of the <span>dialysis bag and a test tube is generally not graduated. A triple beam balance is generally used to weigh mass and not volume. </span>

Answer:
Crossing over
Explanation:
Prokaryotic cells are cells that do not possess a membrane bound nucleus to house their genetic material e.g bacteria while eukaryotic cells possess a membrane bound nucleus that houses their genetic material e.g plants.
One important characteristics of prokaryotic cells is that they do not undergo any form of sexual reproduction, hence, cannot undergo MEIOSIS, which only occurs in sexual reproducing organisms. Prokaryotes reproduce asexually by binary fission.
Crossing over is a unique process that only occurs during meiosis. Since prokaryotic cells do not undergo meiosis, this means that crossing over is the difference between prokaryotic cells and eukaryotic cells in this question.
