Ablue tang is a tropical fish that is blue in color. what property of light waves causes the blue tang to appear blue? as light moves through the water and strikes the tang, only blue light is absorbed. as light reflects off the tang, all colors except blue are diffracted. as light strikes the tang, all colors of light except blue are absorbed. all the colors are equally refracted off the tang, but blue travels the furthest.

As light strikes the tang, all colors of light except blue are absorbed. 

The light that bounces away is the color we see.

hope this helps

Degeneracy

Degeneracy simply means that most of the amino acids produced during protein synthesis from DNA is coded by more than one codon. A codon is a sequence of 3 nucleotides that codes for a specific amino acid.

Because more than 1 codon can produce the same amino acid, the chances of having the synthesis of proteins affected by mutations (i.e. point mutations) is decreased. For example, if the codon with the nucleotide series GAA, which codes for the amino acid glutamate, becomes the codon GAG, the codon will still produce glutamate because the code is degenerate.
