Here is the full statement: A scientist begin working by trying to explain a natural occurrence that is OBSERVABLE.
Scientific method refers to the techniques that scientists used to carry out scientific investigations and it is made up of series of steps. The first step is observation. A scientist normally begin the process of scientific investigation by observing a phenomenon that occur naturally. The observation will lead to questions, which need to be answered and which eventually lead to conduction of experiments.
There are five main fields of environmental science; each one created up of multiple smaller domains.
These five areas are atmospheric sciences, ecology, environmental chemistry, geosciences, and social sciences
<h3>What are three fields within environmental science that focus on non living aspects of the environment?</h3>
Climatology is the study of the Earth's atmosphere and climate. Hydrology is the reflection of Earth's water resources.
Earth science is the analysis of the Earth's nonliving systems and the planet as a whole.
Thus, These five fields are atmospheric sciences, ecology, environmental chemistry, geosciences, and social sciences.

B
Area B of the graph shows the activation energy required if an enzyme was not present
Explanation:
Reactions with high activation energy cannot occur spontaneously. Enzymes are responsible for lowering this activation energy and enabling reactions to occur at a faster pace than natural. An example is carbonic anhydrase enzyme that enables increased rates of carbon dioxide dissolving in and out of blood plasma.
Enzymes distort the bond of reactants such that they become unstable ( this raises the reactants Gibbs free energy). The bonds therefore break and rearrange to form the products of lower and stable energy states.
