Question

the process of linking monosaccharides together to make disaccharides is
dehydration synthesis. dehydration means loss of water. during
synthesis, water is released when two monosaccharides
combine. many more monosaccharides can continue to be added to
the chain, forming a large molecule called a polysaccharide.

the reaction below shows a dehydration synthesis reaction.

during a dehydration synthesis reaction, monosaccharides are
dropdown to form a
dropdown and water is
dropdown.

Explanation:

1. From the text: "The process of linking monosaccharides together to make disaccharides is dehydration synthesis. During dehydration synthesis, water is released when two monosaccharides chemically combine." Also, linking monosaccharides (like forming disaccharides or polysaccharides) involves combining them. So the first blank: monosaccharides are "linked" (or "combined" or "joined") to form a disaccharide (or polysaccharide, but since two monosaccharides form a disaccharide here). The third blank: water is "released" (as per "dehydration means loss of water" and "water is released when two monosaccharides chemically combine").
2. Let's fill each blank:

• First blank: The process is linking monosaccharides, so the action is "linked" (or "combined", "joined").
• Second blank: Two monosaccharides form a disaccharide (the reaction shows two monosaccharides forming a larger sugar, which is a disaccharide; if more are added, polysaccharide, but here two form disaccharide).
• Third blank: Water is "released" (due to dehydration synthesis, loss of water).

Answer:

During a dehydration synthesis reaction, monosaccharides are \(\boldsymbol{\text{linked (or combined/joined)}}\) to form a \(\boldsymbol{\text{disaccharide (or polysaccharide)}}\) and water is \(\boldsymbol{\text{released}}\).

(Note: For the second blank, if considering the reaction with two monosaccharides, "disaccharide" is more precise. If generalizing for more, "polysaccharide" is also correct. The key actions are linking/combining the monosaccharides and releasing water.)
