A, molecular biology
Microbiology includes the study of molecules therefore I believe the answer is molecular biology
Explanation:
Some things consist of only one cell. They are called unicellular organisms. One of the simplest living things, an amoeba, is made of only one cell. Amoebas (sometimes spelled amebas or amoebae) are too small to be seen without a microscope, but they are commonly found in ponds and lakes
You had the right idea about the other option, generally if something is organic it has some sort of atom of carbon within the molecular compound so that limits between the two answers.
The compound is COOH meaning it is a CO² + H (Carbon dioxide + hydrogen)
It becomes an acid because the Hydrogen is a negatively charged ion and makes the compound acidic when bonded to the O
This is a type of acid that also occurs is amino acids, the building blocks of life.
Answer:
Test crosses are used in selective breeding because they can determine the genotype of the parent.
