Explanation / Answer

3. Answer- a) Dehydration

Dehydration synthesis involve reaction which combine organic monomer to produce polymers.

4. Answer- c) Monosaccharides

Carbohydrates are macromolecules. They are a polymer made up of monomers called monosaccharides.

5. Answer- c) Starch

Starch is a polymer which is used as an energy-storage molecule in plants. It is a polymer of glucose and is found in amylose and amylopectin forms.

6. Answer- b) Glucose

Isomers are those compounds that have the same formula but different arrangement of atoms and different structure.

Glucose,fructose and galactose are the three common sugars that share the same molecular formula C6H12O6. But the arrangement of atoms differ in each case.
