<span>As there are no pictures of charts presented to choose from, I will make an educated guess for my answer. For Ron's records to best be recorded, I suggest a stacked line graph to depict the bracket of time each event would've occurred and continuing on with the information leading up to the most recent. It would allow him to visualize the increase or decrease in certain functions and or events that would have taken place during those time periods.</span>
Answer:
The lactose present prevents the production of lactase
Explanation:
This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.
According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.
Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.
