Scientists have used comparative embryology to study and gather evidence of evolution. Karl Ernst von Baer, a Russian scientist, made observations on embryos of different species and came up with four principles of comparative embryology: 1.

Explanation:
Answer:Nitrogen occurs in all organisms, primarily in amino acids
Explanation:
Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids (DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen.-wikipedia
It's shown to widespread in areas where there's a high amount of CO2 in the air, possibly near factories or any buildings that release emissions and have a significant carbon footprint.
Remember, ocean acidification is a large rise of the PH level in water, as it becomes more of an acid as opposed to a base. Carbon dioxide traps heat, and it's possible that the heat contributes to the acidification, as well. The fact that Co2 traps heat is the sole reason for global warming.
