The statement that describes the cell after twenty minutes is this: WATER WILL MOVE FROM THE CELL INTO THE BEAKER RESULTING IN A SMALLER CELL. Osmosis is defined as the process by which the molecules of a solvent move through a semi permeable membrane from the region of lower concentration to the region of higher concentration. For the question given above, the concentration of 30% salt is greater than that of 10% in the cell, so the water molecules will move from the cell [region of lower concentration] into the salt solution [region of higher concentration]. The loss of water will make the cell to shrink and to become smaller.
A) Autotrophs because heterotrophs don't make their own food and rely on other organisms while autotrophs are organisms such as plants who use photosynthesis to make their own food.
petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure.
I think the correct answer from the choices listed above is option B. The difference in biodiversity between the tundra and the tropical rain forest would be that warmer temperatures and higher average rainfall in the tropical rainforest allow more things to survive. Hope this answers the question.
