Answer

Brief Explanations:

  1. The prefix "mono -" means one and "di -" means two. This is based on common usage in scientific terminology for counting units. For the bonding of glucose molecules, in dehydration synthesis, when two glucose (monosaccharides) bond, a water molecule is removed to form a disaccharide (maltose).
  2. When predicting the atom behavior, in dehydration synthesis, an -OH group from one glucose and an -H from the other glucose will be involved in forming a bond and releasing a water molecule.
  3. A. When running the Gizmo, two glucose molecules bond through dehydration synthesis to form maltose.
  4. B. A water molecule (H₂O) is removed when the glucose molecules bond to form maltose.

Answer:

  1. Mono -: One; Di -: Two
  2. An -OH group from one glucose and an -H from the other glucose will combine to form a water - like structure and be removed as the glucose molecules bond to form a disaccharide.
  3. A. Two glucose molecules bonded through dehydration synthesis to form maltose.
  4. B. A water molecule.
