The right answer is the size.

Crystallization is the operation that consists, of a solution (solvent + solute) or a molten solid, to form a crystallized solid. The solute crystallizes in general in a predefined geometrical form (cubic, face-centered cubic, etc.), including or not solvent molecules (eg pure NA2SO4 or [Na2SO4, 10H2O]). The form or chemical formula of the crystals may depend on the crystallization temperature.

There are two ways of crystallization: The dry way and the wet way (in solution)

In crystallization in solution: the solute is initially in the liquid phase in a solvent. It is crystallized (solidification ordered according to a regular structure) within the solution either by solvent evaporation, or by cooling the solution, or both.

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

What is an observation
vagabundo [1.1K]
Hello!

Could be either:

<span>The action or process of observing something or someone carefully or in order to gain information.
</span>
Or 

<span>A remark, statement, or comment based on something one has seen, heard, or noticed.
</span>
And in Science:

 <span>An 'observation' in the scientific sense, is when you make a measurement or evaluation of some sort. You would usually make a note of how something has changed sine the previous ovbservation. Maybe the temperature has changed: gone up one degree; or a crystal has grown: maybe it is now .1 centimeters longer. 

"Observations" usually implies that you are watching some process, and either measuring or noting the change that has taken place. usually you will also want to note the time of the observation, so that you can have an idea of how quickly (or slowly) the changes are occurring.

Hope this All Helps (Hope it did)! Have A Wonderful Day! :)
