The extracellular glucose inhibit transcription of the lac operon (D) by reducing the levels of intracellular cAMP.
Lac operon is the assembly of various genes that are involved in the uptake and metabolism of lactose of E. coli or any other bacteria. It consists of a regulator gene, promoter gene, operator and structural gene. Structural genes are three: z, y and a. Each codes for a different enzyme.
cAMP is the cyclic Adenosine Monophosphate. It is produced by the bacteria when there are low levels of glucose in it. Hence it is also named as hunger signals. Therefore, cAMP is responsible for activating the operon to produce lactose.

Answer:
Reduce, Recycle, and Reuse.
Explanation:
Reduce your use of single-use, disposable, and non-biodegradable items. By doing that, you may be able to decrease the amount of waste you produce on a daily basis.
Recycle your items wherever possible. Separate your items depending on those that can actually be recycled, and those that may not. Before you throw something in the bin as trash, make sure to think about whether the item can be recycled in its entirety or perhaps a part of it can.
Reuse your items as much as possible before you end up replacing them. Only buy essential necessities and choose your products wisely (preferably those with less packaging). Always look for items in your surrounding that can be reused.
Those three ways are very crucial when it comes to achieving sustainable living. At the same time, it helps humans reduce the amount of waste released into the environment.
hope this helps!! p.s. i really need brainliest :)
