RSB [31]

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.

Describe how sandstone, a sedimentary rock, may become a metamorphic rock. Enter your answer in the space provided. HELP 30 POIN
pshichka [43]

Explanation:

When sandstone is overlaid by layers and layers of sediment, it becomes subject to enormous pressure and temperature beneath the layers and its grain structure begins to change. The force of compactness causes grain structure and size to reform. This is called metamophism., The sandstone becomes a new rock called quartzite.  The two rocks will have different properties. Quartzite will have larger crystals and will be hard and smooth while sandstone will be coarse and soft.

<h3>How does DNA function? Why does it matter?</h3>

The biological instructions that give each species its distinctiveness are found in a substance known as deoxyribonucleic acid (DNA). Adult organisms reproduce by transmitting their DNA and the genetic information it carries to their progeny.

<h3>What is the purpose of a person's DNA?</h3>

Genes, which are a component of DNA, are the building blocks of all living organisms. DNA's capacity for recurrent self-replication is its most significant property. DNA must be replicated in order to create new cells, convey genetic information from one generation to the next, and act as a code for the RNA (ribonucleic acid) needed to make proteins.
