The 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.
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.
The oil molecules will not mix with the water because they are hydrophobic, causing the oil-filled sac to remain intact. The oil sac will float in the water due to the difference in density between oil and water. Over time, the oil molecules may slowly diffuse out of the sac into the water, depending on the permeability of the membrane.
The gel-filled space in the chloroplast surrounding the thylakoid stack is called the stroma. It plays a crucial role in the light-independent reactions of photosynthesis, where carbon dioxide is converted into glucose. The stroma also contains enzymes, DNA, and ribosomes, allowing for the synthesis of proteins and other molecules within the chloroplast.
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.
Well what i think is that The water outside of the "cell" will change colors and not the "cell" :D
If the glucose, starch, and iodine pass through the cell membrane, you can perform a color change test. The presence of glucose will show a positive result with Benedict's reagent turning orange/red. The presence of starch will show a positive result with iodine turning blue/black.
To allow water to flow out of a tubing piece filled with a 50% solute solution, the beaker solution must have a lower concentration than 50%, ideally pure water (0% solute). This is based on the principle of osmosis, where water moves from an area of lower solute concentration to an area of higher solute concentration. If the beaker solution has a concentration equal to or higher than 50%, water would not flow out, as the osmotic pressure would prevent the net movement of water from high to low concentration.
Beaker B, which contains the denser liquid, will exert more pressure at the bottom compared to Beaker A filled with water, due to the greater density of the liquid. Consequently, if both beakers are identical in size and shape and filled to the same height, the pressure exerted by the liquid in Beaker B will be greater than that in Beaker A.
The "solution of blue bottle" typically refers to a chemical demonstration involving a blue bottle filled with a solution of glucose, sodium hydroxide, and water. When shaken, the solution turns blue due to the oxidation of glucose, and it can revert to colorless when left to stand, due to the reduction process. This cycle of color change is a classic example of a redox reaction in chemistry.
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.

The hot saltwater will cause the potato cube to absorb the water due to osmosis, while the cold saltwater will cause the potato cube to release water. The difference in temperature affects the rate of osmosis – higher temperatures increase the rate, while colder temperatures decrease it.
