Answer:
You have not consumed lactose from dairy recently
Explanation:
According to the diagram, there is a represssor element in the regulatory region of the operon. This repressor is blocking the RNA polymerase, that is bound to its promoter region upstream of the genes, from transcription. The repressor is mostly the lac repressor that switches of the operon in the absence of lactose.
Answer:
C is Snotase, because it works best in neutral environments (hence the pH of 7)
A is Flotase because it works best in acidic environments (low pH)
B is Zoomase because it works in acidic environments (low pH)
D is Floxase because it works in basic environments (pH above 7)
Note:
For pH, 7 is considered neutral. Anything below that is acidic and anything above that is basic.
