2.Glycogen has both linear and branched chains of glucose molecules.
3.Cellulose has beta 1,4 linkages that cannot be properly digested
Explanation:
Glycogen is a branched polysaccharide consisting of linear chains of glucose with an average chain length of approximately 8–12 glucose units. Glucose units are linked together linearly by α(1→4) glycosidic bonds from one glucose to the next glucose. Branches are linked to the chains from which they are branching off by α(1→6) glycosidic bonds between the first glucose of the new branch and a glucose on the stem chain.Glycogen is a polysaccharide of glucose that serves as a form of energy.The polysaccharide structure represents the main storage form of glucose in the body.
Cellulose is the other major plant polysaccharide. It is the major constituent of plant cell walls. Cellulose is composed on unbranched, linear chains of D-glucose , linked to one another by beta(1-4) glycosidic bonds, which no vertebrate has the capacity to enzymatically digest. Herbivores can largely digest it themselves, because their digestive tracts have microbes that produce cellulases that hydrolyze cellulose.
Glycogen: This is a branched biopolymer that consists of linear chains of glucose residue that are linked together by alpha 1,4 glycosidic bonds. Branches are linked to the chains from which they are branching off by alpha 1,6 glycosidic bonds between the first glucose on the new branch and a glucose on the stem chain.
Cellulose: This is a structural polysaccharide that is found in cell walls of plants and it acts as dietary fiber when consumed. Cellulose has beta 1,4 linkages that can not be properly digested.
Starch: This is a linear chain of glucose molecules attached by alpha 1,4 bonds
The shrinking of a plant cell membrane away from the cell wall when placed in a hypertonic solution is called a plasmolysis... I don't know if that can be of any help :)
The definition of speciation is: the evolutionary process by which populations evolve to become distinct species.
In this scenario, the bears that were once of the same species evolved in order to adapt to their environment. Once they evolved, they could no longer produce with each other, as they are now different species.
