some questions have sub category questions within them. thank you

1: what factors affect that rate of diffusion?

2: what conditions would produce the fastest rate of diffusion?

3: state in which direction water will flow ( into the bag, out of the bag, or in and out at an equal rate ). then justify your answeres using terms hypotonic, hepertonic and isotonic, sub category questions too please.

A: beaker contains 40 % sucrose solution; bag contains 40% sucrose solution

B: beaker contains 25% sucrose solution; bag contains 35% sucrose solution

C: beaker contains 40% sucrose solution; bag contains plain water

D: beaker contains 21% sucrose solution; bag contains 20% sucrose solution

4:? make three drawings on a seprate paper to showing the directions of water movement in the following conditions of tonicity /

1a) Dialysis tubing can be used to make bags that model a cell with a semipermeable membrane. These membranes are impermeable to sucrose but not water. Four bags were filled with the following solute concentrations: Bag A â 10 ml of 1% sucrose Bag B â 10 ml of 20% sucrose Bag C â 10 ml of 45% sucrose Bag D â 10 ml of 80% sucrose Each bag was weighed before placing them in a beaker: Bags B and C were placed in a beaker containing 80% sucrose Bags A and D were placed in a beaker containing 1% sucrose At 15 minute intervals, each bag was blotted dry, weighed, and returned to the same beaker. Q.) After 1 hour â did the weight of each bag change from the initial weight and if it did, how did it change, and why? Be sure to include the terms isotonic, hypotonic, and hypertonic.
