Answer:
The correct answer is "True".
Explanation:
Some species of jellyfish use a form of jet propulsion to swim and get around the sea. For instance, the jellyfish <em>Polyorchis penicillatus</em> contracts its subumbrellar swimming muscles to gain power, which it uses as mechanical energy to perform a jet cycle while swimming. Some studies in this regard have been performed, measuring even the amount of energy needed in the muscles for the jellyfish to swim.
Weathering and erosion played a big role in forming the grand canyon. The rock was being weathered, most likely mechanical weathering, and then it eroded away. Think of a pebble that is in running water. When you pick it up, it is smooth, right. But before, it was pointy. So, the grand canyon was once a big rock, and weathering broke through it making it one of the wonders of the USA.
Answer:
When the cell has 0% sucrose I expect the cell to stay the same.
Explanation:
First of all, this question should not be confused for the statement "When the "cell" has 0% sucrose, did you expect the cell to have gained water, lost water, or stay the same. In this case, the correct answer would have been; gained water.
But, in this question, we are asked what happens to the cells at 0% sucrose concentration. At 0% (no solute) concentration, there is no net movement of water or solute into or out of the cell, because the cell is isotonic to the external environment (distilled water). Osmosis, a special kind of diffusion, is the movement of water, from areas of lower solute concentration to area of higher solute concentration, or from areas of higher water concentration to areas of lower water concentration through a semi-permeable membrane. If the water moves into the cells (hypertonic cells), then the cell gains water and increases in size, but if the cell loses water (hypotonic cell), then it reduces in size
