proteins are made of amino acids  

The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain. ... The primary structure of a protein is determined by the gene corresponding to the protein. A specific sequence of nucleotides in DNA is transcribed into mRNA, which is read by the ribosome in a process called translation

Hemoglobin is a protein that is used to carry oxygen through the bloodstream from the lungs to the tissues. This is important for survival. Hemoglobin has a lower affinity for oxygen the lower the concentration of oxygen gets. This has great implications for the human body and has helped us adapt very effectively. :-)

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
