2. the packet which was kept in the refrigerator did not have bad smell because they did not come in contact with oxygen.
Explanation:
rancidity - when fats and oils are oxidised they become rancid and their smell and taste changes.
when eatbles come in contact with oxygen they oxidised due to this we get bad smell and taste from it .

Explanation:
It is a regular occurrence for dialysis bags or dialysis tubing to be employed in permitting smooth movement of molecules when having to do with a fluid. These bags are normally evaluated to ensure that the client has adequate amount in th bag so as to be able to achieve the goal at hand.
If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.
At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E.
The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.
