Biology, and/or biochemistry.
The knowledge of the DNA, is achived through reasearching the chemical processes of cell division. This includes the research of biological and chemical processes of the living body and cell structure. Molecular physics may also be included in the field.

The study of the barometric pressure of the atmosphere above Florida would fall under the field of meteorology, specifically within atmospheric science. Meteorologists use atmospheric pressure measurements to understand and predict weather patterns and changes in the atmosphere.
Living things fall under the scientific branch of biology, which is the study of life and living organisms. Biology focuses on studying the structure, function, growth, evolution, and interaction of living organisms.
Newton provided the rules and formulas to understand how forces work. Without this understanding, our civilization would not exist.
Corn and barley are commonly associated with the discipline of plant biology or botany, which is a branch of life science that focuses on the study of plants, their structure, physiology, genetics, and interactions with the environment.
Nutrition would be the broad field.
The design and construction of a fantastic foamy fountain would fall under the category of engineering.
That would be the science of Accoustics .
The study of the internal structure of living organisms is called Anatomy, so it is the branch of Biology. Another name of Anatomy is Morphology.
Urban planning would fall under social science.

Structure is a general word in science as in any field. It means 'how things are built' just as it would anywhere else. You might speak of the structure of a cell or an organism. For instance the structure of a bacterial cell differs from that of a mammalian cell in not having a nucleus. In chemistry it refers to how the particles of a substance are fitted together, for instance the special properties of diamonds result from its structure: a 3-d network of carbon atoms bound by covalent bonds.
You would find biology in life science. Measuring the rate of squirrel birth in a woodland habitat
