Answer:
The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light.
Explanation:
Parasitism; the tick benefits from the human, the host.
Answer:
oligosaccharides
Explanation:
Oligosaccharides are basically carbohydrate polymer that contain 3 to 9 monosaccharide residues connected by glycosidic linkages. They are normally present as glycans.
Oligosaccharide linked to lipid(as in glycolipid) or to amino acid side chain in protein(as in glycoprotein) via<u> </u><u><em>N-glycosidic bonds or O- glycosidic bonds</em></u><em>. N</em>-Linked oligosaccharides are always pentasaccharides attached to asparagine via a beta linkage to the amine nitrogen of the side chain.Whereas,<em> O</em>-linked oligosaccharides are generally attached to threonine or serine on the alcohol group of the side chain.
Glycoproteins have a specific oligosaccharide structure that has a profound effect on many of their properties affecting critical functions such as cell surface receptors, immunoglobins etc
Glycolipids are mainly found in lipid bilayer. They are important for cell recognition and for modulating the function of membrane proteins that act as receptors.Here the head of oligosaccharides serve as a binding partner in receptor activity.
