∙ 10y agoThe starch indicator solution will diffuse out of the bag (cell) into the beaker, changing the color of the starch solution to a blue, purple, or black color (assuming that it's iodine). The color of the indicator solution inside the bag will not change, because only the glucose can diffuse into the bag, but the starch cannot diffuse into the bag.

∙ 12y agoWell what i think is that The water outside of the "cell" will change colors and not the "cell" :D

∙ 13y agoyes there is a reaction between glucose solution and starch indicator.
Water will enter the sac and it will swell
Water will enter the sac and it will swell
The cell membrane is a selectively permeable membrane that will only let water and solutes across it. The cell membrane freely allows pretty much everything to pass across it, meaning that things unable to pass the membrane back up and push it away from the cell wall. Therefore the gap is filled with the SUGAR SOLUTION that is surrounding the cell.
1. Place a small amount of starch powder in a test tube filled with cold water 2. Boil it to make a clear solution 3. Once the solution has cooled off, you should put 3 or 4 drops of iodine solution in it. 4. The solution should turn dark blue.
The animal cell is in an isotonic solution, and the plant cell is in a hypotonic solution

place starch solution inside the partially permeable membrane and than partially submerge it a beaker filled with distilled water. after some time, take the tubing out and test the water inside the beaker for starch by adding iodine solution. if the tubing is permeable to starch, the starch would have diffused into the water in the beaker and test positive for starch and turn dark blue. if not, then the water in the beaker would test negative for starch and remain a yellowish brown solution.
A patato cube is placed in a beaker filled with hot salt water and another patato cube is placed in a beaker filled with cold salt water?
Beaker
Glucose is filled with all types of vitamins and minerals
No, distiled water will not conduct electricity.
I have seen beakers with filled capacities from 25 mL to 5 liters.
If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.
