It is definitely not a primary source: this would be a book itself.
Now, is it a tertiary source? I don't think so: the author of the review should have read the book and should only be referring to this book in the review.
I think it's a secondary source.
<span>For question 1: we know the vA=10.0 cm3 and the m=89.6g. Using the equation D = m/vA give us: D = 89.6/10 = 8.96 g/cm3. Answer is (C) 8.96 g / cm3.
For question 2: We know the vA=1.2 cm3 and the D=.6 g/cm3. Using the equation D = m/vA and rearranging for m gives us m = D*vA: m = .6 * 1.2 = .72 g. Answer is (D) .72 g.
For question 3: We know the D = 8 g/cm3 and the m = 600g. Using equation D = m/vA and rearranging for vA gives us vA = m / D: vA = 600 / 8 = 75 cm3. Answer is (A) 75 cm3.</span>
Oxygen is used up in the body of most organisms and Carbon dioxide is released. The body uses oxygen to break down glucose to supply energy tot he body. In result of this reaction carbon dioxide and water is released into the system along with energy. The carbon dioxide is then exhaled into the air by the respiratory system of the organisms.
Answer:
- Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. ( A )
- There are more than one tRNA with the 5' CAU 3' anticodon. ( B )
- The N-formyl group attached to methionine prevents fMet from entering interior positions in a polypeptide. ( D )
Explanation:
The statements that explains how N--formyl methionine (fMet) is only associated with the 5' AUG initiation codon and not with internal AUG codons, given that methionine in both cases in encoded by an AUG in the mRNA are :
Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. ( A )
There are more than one tRNA with the 5' CAU 3' anticodon. ( B )
The N-formyl group attached to methionine prevents fMet from entering interior positions in a polypeptide. ( D )
While statement C is wrong.
