When glucose is high, cAMP is low; CAP does not bind the lac operator, and RNA polymerase does not bind the lac promoter. CAP is only active when glucose levels are low, which means the cAMP levels are high, and therefore the lac operon can only be transcribed at high rate when glucose is absent. The importance of this is that the bacteria only turns on the lac operon and start using lactose only after they have used up all the preferred energy source which is glucose.
Answer:
Energy makes it all happen. The Sun radiates huge amounts of energy. Only a small portion of that energy hits the Earth, but it is enough to light our days, heat our air and land, and create weather systems over the oceans. Most of the energy you will learn about comes from the Sun.

Brainliest please?
What was the investigation? But from my best guess I'm assuming it's the second option. This may be incorrect.
<h2>The quality and quantity of DNA in cells remain the same from generation to generation.</h2>
Explanation:
- As all organisms depend on their DNA to live, and any changes in the amount or quality of DNA. It will lead to mutations or death of the organism.
- If DNA is changed then it will be difficult for the chromosomes to match up and offspring will not be produced.
- The quality must be maintained. Otherwise other system in the body will not work properly.
It is where the cells become too large and the DNA can't keep up with the demands of the cell so then the proteins will stop being made and then the cell will finally stop growing
