Answer:
The correct answer is ''The scientific study of heredity''
Explanation:
Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.
Answer:
Explanation:
Hard-shelled organisms absorbed calcium and carbonate iron and use them in making their hard shells which are calcium carbonate. When these organisms die, there shells are used in the formation of limestone rock. Limestone rocks are a huge store carbon. When acid rain reacts with limestone, these trapped carbon are released to the atmosphere thereby causing an Increase in atmospheric carbon.
Conclusively, the accumulation of limestone rock and subsequent reactions with acids such as acid rain has resulted in an increased atmospheric carbon throughout the years.
