Answer: lac operon is enhanced when CAP-cAMP complex interacts with rna polymerase.

Explanation:

The operon is defined as a set of structural genes organized in sequence and under the control of a single promoter. RNA polymerase transcribes, from the common promoter, all the structural genes into a single polycistronic RNA molecule, which is translated into the proteins encoded by the genes.

The CAP-cAMP Complex acts positively by providing the basic conditions for transcription. The complex binds to the lac promoter and doubles the DNA of this region, which allows it to be recognized by the RNA polymerase. In the absence of cAMP or CAP protein, the process of transcription does not occur because the RNA polymerase does not recognize the Lac promoter. When the CAP-cAMP complex is present, the promoter is recognized by the RNA polymerase, which binds to it. The CAP protein is, therefore, an activator and the cAMP an effector.

Why is homeostasis particularly more important to unicellular organisms than multicellular organisms?

ElenaW [278]

Multicellular organisms do this by assigning specific roles to specific cells. This enables various cells within a larger organism to collaborate in order to preserve homeostasis. Since they are made up of just ONE type of cell, unicellular organisms do not need cell specialization to maintain homeostasis.

Answer:

It led to a wide range of protests by the people which brought about revolution

Explanation:

The ultimate consequences of wealth inequalities during the 18th century was wide range of protests by the people which brought about revolution.

This was because of the high poverty rate and difference between the classes in the society as the rich got richer due to policies which favored them while the poor got poorer due to the bad policies which made them register their displeasure and move for a revolution.
