Answer:
For a scientific hypothesis to be useful, it must be a
<u>testable</u> explanation of facts
Explanation:
In the scientific method, the hypothesis represents the starting point of all research, where the observation of a phenomenon is followed by a possible explanation that must be measured and proven.
It is important that the hypothesis presents defined, specific and real variables, and there must be the possibility of test it and have the necessary tools for this purpose.
Regarding other options:
<em> A. Provable
: the probability of a hypothesis implies that it may or may not be true.</em>
<em> B. Widely accepted
: the explanation that provides a hypothesis needs to be demonstrated through experiments in order to be accepted.</em>
<em> C. Correct: the hypothesis will not be correct until it has been tested.</em>

Answer;
-Inhibitors
Chemical mechanisms that can turn off or reduce an enzyme are inhibitors.
Explanation;
-Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity. They can bind to an enzyme and stop a substrate from entering the enzyme's active site and/or prevent the enzyme from catalyzing a chemical reaction.
-Enzyme inhibitors are classified as either competitive or non-competitive inhibitors. Competitive inhibition occurs when the substrate and a substance resembling the substrate are both added to the enzyme.
-Non-competitive inhibitors are considered to be substances which when added to the enzyme alter the enzyme in a way that it cannot accept the substrate.
