Polysaccharide structure can be varied by differences in ________.
Scilla [17]

Answer:

monomers of MONOSACCHARIDES

Explanation:

Polysaccharides are large molecules formed from chains of POLYMERS linked together by glyosidic bonds. <u>MONOMERS are small sub units that formed polymers, they are therefore the building block of a polysaccharides.  The monomers of polysaccharides are called monosaccharid</u>es (1 sugar molecule.) when two of these are joined together they formed disaccharides (two sugars.)

Polysaccharides are fromed by joining  together condensation, (loss of water molecules,)  of mutiple monosaccharides units and the reversal of this to add water molecules to sepate them to monosaccharies is  sugar Hydrolysis.

Example of polysaccharides are starch, glycogen cellulose

Example of monosaccharides are glucose, galactose.

Disaccharides are common table sugar, sucrose, maltose, lactose

Which term refers to the energy an object has due to its position?
puteri [66]

Answer:

Potential Energy.

Explanation:

Potential energy, stored energy that depends on different parts of the system's relative position. When compressed or stretched, spring has more potential energy.

A stainless steel ball has more energy than it had when it fell to the world. It is able to do more work in the raised position.

Potential energy is a system's property and not a single body or particle. The earth-consistent system and raised ball, for instance, have greater potential energy as the two are more distinct.
