Answer:
glycosidic bonds between monosaccharides that combine to form polysaccharides
Explanation:
The building blocks of carbohydrates are individual monosaccharides (i.e., sugar molecules), such as glucose, fructose, glucuronic acid, galactosamine, glucosamine, etc. These individual monomers of carbohydrates bond to form polysaccharides such as cellulose and starches. Monosaccharides form glycosidic bonds with an alcoholic OH group of a second monosaccharide to form a disaccharide (for example, lactose), and then these larger molecules bond together to form either linear or branched polysaccharides. Starch, for example, is a polysaccharide composed of monomers of glucose molecules.

Answer:
X inactivation
Explanation:
The female mammals have double the number of X-linked genes as compared to their counterpart males. During early embryonic development, either the maternal or paternal X chromosome in all the cells of a female is inactivated by the process of heterochromatinization. The inactivated X chromosome is present in the form of a Barr body. This inactivation of the X chromosome is a random event.
The inactivated X chromosome of a cell remains in the same state in all of its progeny cells. In this way, the process of X inactivation balances the dosages of X-linked genes between males and females.
