Ocean acidification is of considerable concern to environmental scientists as it could impact ocean biodiversity significantly. As
carbon dioxide levels increase in the atmosphere, the diffusion of this gas increases in the oceans too. The formation of carbonic acid
can impact species, as the lowered pH can cause weakening of shells made of calcium. Which of these species is not directly impacted
by ocean acidification?
A)
Sea turtles
Oysters
Corals
D)
Clams

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
