If the tubing was permeable to starch which way would the starch move into the tubing or out of the tubing?

Solutions tend to move from areas of high concentration to areas of low concentration. So if a bag is permeable to starch, the starch will rush into the bag.

What membrane that allows only some materials to move in and out of the cell is?
Such a membrane is said to be selectively permeable or semi-permeable.
What makes the cell membrane selective permeable?
A cell membrane is selectively permeable because it only allows particles to move across them due to different concentrations. Molecules move from areas of low concentration to high concentration.
Does lactose move across dialysis tubing?
yes, because it is a simple carbohydrate
How do particles move through a permeable membrane according to diffusion?
Yes, that is very true, especially with osmosis (the passing of water through a selectively permeable membrane).
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.
Are membranes selectively permeable if they allow only certain substances to move across them?
False.
How do you keep cats from chewing plastic oxygen tubing?
You can pick up flexible silicon tubing 5/16" at any hardware store. Get it the same length as the oxygen tubing you want to protect. Ask the store to slit it all the way along its length on one side, so that the O2 tubing can be pushed into the outer tube, which will close up around it. The outer tubing protects the inner tube, and the cat may try to bite it, but will not get through to the inner tube, so the oxygen keeps flowing. The silicon tube is flexible enough to move very much the way the O2 tube would move, and it gives great peace of mind.
What substance can diffuse through a differentially permeable membrane?
Diffusion across a membrane in biology is referred to as 'osmosis' & osmosis is the process by which solvent molecules move from a region of high conc. to low concentration and this can therefore occur only in one direction at a time for a perticular solution. this is a really smart answer im surprised
What is the area where water from the surface can move through permeable rock to reach an aquifer is called?
thanks for nothing
Can all particles move across the cell membrane?
no, membranes are selectively permeable, letting somethings in and not others
A membrane that allows only some materials to move in and out of the cell is . permeable semipermeable rigid bilayered?
"semipermeable"
Why is an advantage for plants to store products of photosynthesis as starch and not sugar?
Starch does not dissolve in the fluid in the cell, so does not affect water potential. Sugar does dissolve, so would reduce water potential of the cell and cause water to move in to the cell by osmosis.
