An artificial cell made of dialysis tubing is filled with a 6% sucrose solution. The dialysis tubing is permeable to water but not to sucrose. Which of the following statements most accurately apply to the artificial cell when it is placed in the solution in beaker A? a. the cell will be hypotonic to the beaker solution and will decrease in weight b. the cell will be hypertonic to the beaker solution and will increase in weight c. the cell will be hypotonic to the beaker solution and will increase in weight d. the cell will be hyertonic to the beaker solution and will decrease in weight e. the cell will be isotonic to the beaker solution and no change is weight will occur

Answer 1

Answer 41:) True

Both molecules contain hydrogen atoms bonded with oxygen atoms. These hydrogen atoms can make hydrogen bonds with water molecules.

Answer 42:) True

Both molecules are pentose sugar in which the left one is ribose sugar while the right one is deoxy-ribose sugar.

Answer 43:) False

Only deoxyribose sugar is found in DNA while ribose sugar is used in RNA.

Answer 44:) True

Yes, only ribose sugar is used in RNA.

Answer 45:) False

No, the left image is showing ribose sugar because it contains the 2’OH group. The right one is deoxyribose sugar.
