Assume the bag is permeable to water and you have made sure that your bags did not leak. 6. Identify the SPECIFIC transport process that is demonstrated by the results in Table 2. 7. List the beaker number or numbers that demonstrated a NET movement of water. 8. Provide an explanation for the observed differences in weight gain between sacs 1 and 3. 2. beakers , 3, y Specifically, why did sac 3 gain more weight than sac 1? cl Because, the beaker g d'stitea wbter and la S moillers an a Went paster. no Caf nohalnd Salt 9.

6. Here the transport process is osmosis. Osmosis is defined as the movement from low concentration to high concentration. Here, distilled water is moving to higher concentrated area.
7. Beaker 1, 3 and 4 have net movement. Beaker 2nd has no net movement because of same osmolarity.
8. Here sac 3 has high weight gain because of high osmolarity of salt solution. Osmolarity is greater if the concentration of salt is higher. Here sac 3 has 40% salt while sac 1 has 5% glucose.
9. Yes, the data form beaker is scientifically valid. Here water moves from sac (low concentration) to the beaker (high concentration) via the process of osmosis because of high osmolarity in beaker.
