Is the baggie or the beaker more concentrated in starch?
baggie
Kate and Janie are about to pour water into a beaker when they notice the beaker has a crack at the bottom. What should the students do with the beaker?
Inform their teacher and then throw the beaker in the broken glass
What are the uses of a beaker brush?
A beaker brush cleans the inside of a beaker after you are finished using it.
What is the difference between a graduated beaker and beaker?
A graduated beaker has markings, either etched or painted, which indicate approximate volumes at several levels of the beaker.
What is the compound deposited on the inside of the beaker?
You will need to tell us what was put into the beaker and what, if anything was done to the beaker. For instance, was the beaker heated? And resubmit your question.
Is a baggie or beaker more concentrated in starch?
It is of course going to be the baggie...why not!

How can you tell if glucose starch water and iodine passes through the cell membrane?
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.
What will happen if you pour starch indicator solution into the cell and filled the beaker with starch and glucose solution?
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.
What would happen if you poured starch indicator solution into the cell and filled the beaker with starch and glucose solution?
Well what i think is that The water outside of the "cell" will change colors and not the "cell" :D
What do you use the beaker for on Poptropica Steamworks?
Enter the restaurant and the lady there will give you milk.
How can you test a plant leaf for photosynthesis?
leave it in sunlight and water it, use a starch indicator to test presence of starch, or put an aquatic plant in a beaker of water and put a test tube upside down in the beaker surrounding the plant and leave it in sunlight and you should eventually see oxygen bubbles start to form up from the plant through the test tube
Can starch pass through a cell membrane by diffusion?
Within a plant cell, starch is basically stored energy. Starch is composed to cross sugar molecules that are cross linked to form larger chains of sugar molecules that are better for storage. When the need arises, these larger chains are broken down to sugar molecules and are utilized by plant cells to carry out various biological processes. Starch is a large polymeric structure and does not typically pass through cell membranes.
How does Lugol's solution work as an indicator?
An indicator is a substance that changes colour in the presence of another substance. Let say inside the beaker are substances of both glucose and starch. The glucose and starch are of same colour. By injecting the lugol's solution into the beaker, the lugol's solution changes colour in the area of where starch is, while no colour changes in the presence of glucose. Thus, by using the Lugol's solution which only acts as indicator for starch and not glucose, we could tell part which area floats around with glucose and starch substances. Lugol's solution works as an indicator because it will stain starches due to iodine's interaction with the coil structure of the polysaccharide.
Do the carbohydrates you eat in the form of starch enter your cells?
No, they contain too much oxygen so they can't enter our cells. They do however sectrete chemicals, and these chemicals enter the cell
What results would you expect of the experiment started with a glucose and IKI solution inside the bag and only starch and water outside?
The IKI Is small so the pores of in the bag allow it to go throuch but the starch is to big. So based on the size of the molecules, the glucose and IKI would move out of the bag, the water in, and the starch left in the beaker.
What will happen when a membrane sac filled with large molecules of oil is suspended in a beaker of water?
Water will enter the sac and it will swell
