Thermal pollution is when the water temperature goes from one extreme to another whether cold to hot or hot to cold, so I would say B. 
        
                    
             
        
        
        
mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.
A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in <u>translation</u>. 
Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for<u> protein synthesis</u>.
 
The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and<u> protein synthesis</u> is facilitated by this <u>amino acid</u> sequence. 
<u>The genetic code</u>, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code). 
Thus mRNA contains the code that specifies the<u> sequence of amino acids</u> in a polypeptide chain.

Answer:
Red blood cells and blood plasma do not contain DNA. Red blood cells don't have the DNA containing nucleus and mitochondria. Only white blood cells in blood contain DNA. With blood donation, usually most of the white blood cells are filtered out.
Explanation:
because red blood cells don't have the DNA containing nucleus and mitochondria
