Question

define the term disaccharide
a saccharide that is a different color
a sugar that can cause cell death
two sugar monomers bonded together

Explanation:

To define a disaccharide, we recall biochemical concepts. A disaccharide is a type of carbohydrate (saccharide) formed when two monosaccharide (sugar monomer) units are linked together via a glycosidic bond. The option "two sugar monomers bonded together" matches this definition. The other options are incorrect: a disaccharide's definition isn't about color, and causing cell death is not a defining characteristic of a disaccharide.

Answer:

the option with "two sugar monomers bonded together" (the first option among the choices shown)
