which of the following correctly describes a reaction that forms a disaccharide from two monosaccharides?

Answer Options:

a. glycogen + fructose = maltose

b. galactose + glucose = lactose

c. glucose + sucrose = fructose

d. maltose + lactose = cellulose

b. galactose + glucose = lactose

Explanation:

Monosaccharides are single units. Disaccharides are molecules of two monosaccharides joined together.

Examples of monosaccharides include glucose, fructose, and galactose.

Examples of disaccharides include lactose, maltose, and sucrose.

The only example that shows this is b.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
