Adialysis sac that is permeable to glucose and water is filled with water and placed in a beaker containing 20% glucose solution. will there be a net transport of glucose across the dialysis sac? if so, in which direction will the glucose move, into the sac or out of the sac? answer both questions

The dialysis sac is not only permeable to water, but also to glucose. If the glucose could moves between the sac, then it would move from higher concentration into lower concentration. The sac consist of water (have 0% glucose concentration) while the beaker containing 20% glucose solution, so the glucose from the beaker should move toward the sac. The final concentration will depends on the ratio of volume of the sac and the beaker.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
