1. draw arrows indicating the net movement of each material. you can draw an arrow in google slides by going to insert line arrow. label each arrow by dragging and dropping the provided \glucose\ or \water\ text boxes.
2. is the solution in the beaker isotonic, hypertonic or hypotonic to the solution in the bag? label each solution under the picture using the provided text box.
3. are these substances moving across the membrane by active or passive transport? explain.
4. describe how the appearance of the bag at \a\ might change after a period of time has passed.

Accepted Answer

# Brief Explanations:
1. Without the actual picture showing concentration gradients, we assume that water moves from an area of high water - potential (low solute concentration) to an area of low water - potential (high solute concentration) and glucose moves according to its concentration gradient.
2. If the solute concentration in the beaker is higher than in the bag, it's hypertonic; if lower, it's hypotonic; if equal, it's isotonic.
3. Passive transport occurs along a concentration gradient without energy input, while active transport requires energy. Water usually moves by osmosis (passive), and glucose may move passively by facilitated diffusion or actively if against its concentration gradient.
4. Depending on the net movement of water, the bag may swell if water enters (hypotonic external solution), shrink if water leaves (hypertonic external solution), or remain the same (isotonic).

# Answer:
1. Cannot be answered without the picture to determine concentration gradients for drawing arrows.
2. Cannot be answered without knowing solute concentrations in the beaker and bag.
3. Water usually by passive transport (osmosis). Glucose: could be passive (facilitated diffusion) or active depending on concentration gradient. Explanation: Passive transport follows concentration gradient, active transport requires energy to move against it.
4. If the beaker solution is hypotonic, the bag may swell. If hypertonic, it may shrink. If isotonic, it may remain the same.
