What is one thing that all polysaccharides have in common?

a. the amount of branching remains constant.

b. the number of glucose molecules is always the same.

c. glucose molecules are always bonded to each other in the same way.

d. all polysaccharides are made up of carbon, hydrogen, and oxygen.

Answer;

D. All polysaccharides are made up of carbon, hydrogen, and oxygen.

Explanation;A polysaccharide is a large molecule made of many monomers called monosaccharides such as glucose, galactose, fructose, etc.Polysaccharides can be homopolysaccharides, where all monosaccharides are the same or heteropolysaccharide in which the monosaccharides vary.They may be linear, where a molecule of polysaccharides has straight chain of monosaccharides, or branched polysaccharides in which a chain has arms.All polysaccharides contain oxygen, hydrogen and carbon atoms like all the carbohydrates.

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.
