organic A type of matter that contains carbon and hydrogen and is found in all biological systems that can further decompose
pH The measurement of hydrogen ions in a solution
ribonucleic acid A type of nucleic acid found in all living matter composed of adenine, cytosine, guanine, and uracil and is responsible for synthesizing proteins
