13. A dialysis bag is filled with distilled water and then placed in a sucrose solution. The bag is permeable to sucrose, not water. The bag's initial mass is 20g, and its final mass is 28g. Which of
these statements best explains why the dialysis bag increased in mass?
A. Because the bag was placed in a solution with a higher sucrose concentration than that of the
bag, the semi permeable membrane allowed for sucrose to diffuse into the bag.
B. Because the bag was placed in a solution with a lower sucrose concentration than that of the
bag, the non permeable membrane did not allow for sucrose to diffuse into the bag.
C. Because the bag was placed in a solution with a higher water concentration than that of the
bag, the semi permeable membrane allowed for sucrose to diffuse out of the bag.
D. Because the bag was placed in a solution with the same sucrose concentration as the bag, the
semi permeable membrane allowed for sucrose to diffuse out of the bag,

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:

the answer is b. glad to .

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
