Question

when two monosaccharides undergo a dehydration synthesis, a starch is formed. a disaccharide is formed. a polysaccharide is formed. hydrolysis occurs. two new monosaccharides are formed.

Explanation:

Dehydration synthesis is a chemical reaction where two monosaccharides combine by losing a water - molecule. A disaccharide is a sugar formed by the joining of two monosaccharides. Starch is a polysaccharide made of many glucose units. Polysaccharides are long - chain polymers of monosaccharides. Hydrolysis is the opposite of dehydration synthesis. And new monosaccharides are not formed in this reaction.

Answer:

B. a disaccharide is formed.
