Answer:

Here the fucose is linked to galactose by alpha1,2 glycosidic linkage.

Explanation:

Fucose is a deoxy sugar consist of 6 carbon atoms which means fucose is a hexose sugar.

   Fucose does not contain -OH group at C6 carbon that"s why it is termed as deoxy sugar.

     Fucose can link to both Nactylglucosame by alpha-1,6 glycosidic linkage and to galactose by alpha-1, glycosidic linkage  generates the H antigen.

   As donor is blood type B that means fucose is linked to galactoseof H antigen by alpha 1,2glycisidic linkage.

Sladkaya [172]

Answer:

The correct answer is option 4.  Parasympathetic division.

Explanation:

The parasympathetic division is one of the three divisions of the ANS or autonomic nervous system. It also helps in the rest system or digest system as it saves energy by slowing the heart pace by slowing the rate of contraction. This is performed with the help of nerve fibers that send signals.

Parasympathetic nerve division increases the intestinal and activity gland. This nerve division helps in relaxing the sphincter muscle in the GI tract.

Thus, the correct answer is option D.
