A 10% glucose solution is placed in the thistle tube. The thistle tube is placed in a beaker that contains a 5% glucose solution
. There is a differentially permeable membrane across the broad end of the tube, which is permeable to water but not to the sugar glucose. What will occur over time to the water? To the solute?
The thistle tube has 10% glucose solution and it is placed in a beaker containing 5% glucose solution. Since the concentration of solution is higher in the tube, it is hypertonic compared to the outside solution. The membrane is permeable to water but not to glucose molecules so the process of osmosis can take place. Osmosis is the movement of solvent molecules from less concentrated to high concentrated solution. Here, the outside solution has lower concentration of glucose so water will move from here to the tube. Eventually, solute concentration will start to decrease inside the tube. Net movement of water will become zero when the two solutions become isotonic i.e. there is no difference in concentration between them.
Fungi lack chloroplasts and are heterotrophic organisms and so require preformed organic compounds as energy sources. With plants: Fungi have a cell wall and vacuoles.
<span>I think that inhalants are a delivery method and not necessarily a drug type. The other three listed are actual drug types and are used in physical and mental health prescriptions. Inhalants are typically non-prescription/illegal drugs.</span>
