I assume this photo has the labels you are talking about.

DNA double helix consists of two strands that wind around each other with their nucleotides liked.-> it's the structure number 5
nucleosome- it's a segment of DNA wound in sequence around eight histones (proteins)- number 2
Histone- proteins with DNA around them, forming the nucleosome- number 4
Tight helical fiber- chromatin coiled very tightly- 3
Cromosome- chromatin condensed even tighter forming a X shape.- 1

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. MONOMERS are small sub units that formed polymers, they are therefore the building block of a polysaccharides. The monomers of polysaccharides are called monosaccharides (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
