Answer:
1.Observation and description of a phenomenon. The observations are made visually or with the aid of scientific equipment.
2.Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation.
3.Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. If experiments do not confirm the hypothesis, the hypothesis must be rejected or modified (Go back to Step 2).
4.Establish a theory based on repeated verification of the results.

I believe the answer is D. A reactant that is catalyze a by an enzyme.
Answer:
The pressure of a gas increases in a closed container if the volume of the gas decreases. Pressure and volume have inverse relationship which means if one increases the other decreases and vice versa. If pressure increases, volume of a gas decreases because there are a lot of empty spaces present between gas particles which are filled when gas particles come closer to each other due to pressure applied.
Answer:
Complex carbohydrates are MADE up of sugar molecules that are strung together in long complex chains, complex carbohydrates are found in food like peas, beans, whole grains and vegetables.
Explanation:
Both SIMPLE and COMPLEX carbohydrates are turned into glucose (blood sugar) in the body and are used as energy.
I really hoped this helped some, I tried to make it specific :[
