A mixture can vary in composition, but a pure substance has a set composition.
Answer:
The genes of the lac operon will be transcribed continuously
Explanation:
The operator is a sequence in the DNA which binds a repressor protein. THe operator is located upstream ('before') the structural genes of the operon.
When this repressor is bound to the operator it blocks the RNA polymerase from transcribing the structural genes.
If the operator is moved downstream (to the far end) of the operon, past the last structural gene, the repressor will stop being an obstacle for transcription and the RNA polymerase will always be able to transcribe the structural genes.

High cholesterol<span> can lead to the buildup of plaque in </span>artery<span> walls. This buildup is called atherosclerosis. It can lead to coronary </span>artery<span> disease (CAD), heart attack, stroke or transient ischemic attack (TIA), and peripheral </span>arterial<span>disease</span>
<span>take the .9 meters it has to travel and multiply that by the 1 second it take to get 150 meters. Next all we have to do is take the product you get form that and divide it by the 150 meters. You should end up with 0.006 seconds to get 0.9 meters in the nervous system</span>
