An mRNA strand is 108 nucleotides long. The maximum number of amino acids that could form in the resultant polypeptide chain is

36 amino acids

Explanation:

A messenger RNA (mRNA) is a type of RNA formed during transcription of DNA. mRNA contains nucleotide bases that are read in a group of three i.e. triplet called CODON. Each codon specifies a particular amino acid when translated.

Hence, in an mRNA strand that is 108 nucleotides long. This mRNA sequence will be read in three's with each three nucleotide corresponding to one amino acid. Hence, to get the maximum number of amino acids that could form in the resultant polypeptide chain, we divide as follows:

108 bases ÷ 3 bases (codon)

= 36 amino acids

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 

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
