Answer:
C
Explanation:
This is what is referred to as peer-reviewing. To gain veracity for her results, the fellow scientist replicates the experiment under the same parameters that she did and determines if the same results are achieved, If so, the results and experiment gain veracity and can be quoted on other scientific journals. For the experiment to be replicated, it needs to be clearly defined in the report, a requirement for all scientific reports.
In the above question, if the bag refers to a dialysis bag, the membrane of a dialysis bag is a selectively permeable membrane that does not allow the movement of all molecules to diffuse across the ,membrane. Osmosis is best explained with the help of a dialysis bag. In the process of osmosis the movement of water molecules from their higher concentration to lower concentration take place across the membrane.
Thus, only water molecules will pass across the bag and limit the movement of other molecules.
