Glycoproteins:. a. contain unbranched oligosaccharides.
b. are a small fraction of the total number of proteins in a human cell.
c. are many of the cell surface and extracellular proteins.
d. have oligosaccharides covalently attached to aspartate residues.

Explanation:

Glycoproteins have oligosaccharides covalently attached to aspartate residues (type of amino acids) . They are not unbranched oligosaccharides.

Explanation:

Glycoproteins have oligosaccharides covalently attached to aspartate residues.

They are proteins which contain oligosaccharide chains that are covalently attached to the amino acid side-chains.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

geologic time scale (for gradpoint) =)
