In science class, maria observes that a white-colored flower has shades of red when it’s watered with red-colored water. she forms a hypothesis that the color reaches the flower through the stem. what should maria do to confirm the hypothesis?

An observation was recorded by the Maria in the class that white flowers show red patches when colored with the stem. She proposed the hypothesis that color reaches the flower through the stem.

To test the hypothesis she will perform a "scientific experiment" where she would divide the samples into two groups: control and experimental. In the control samples, she will grow the plants in red samples with no stem whereas in the experimental group she will grow the samples in different concentrations of red color with stems. This will help confirm her hypothesis.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
