In the lac operon, glucose also plays an important role along with lactose. When Lactose is present in the environment along with glucose then it cannot deactivate the regulator gene [repressor], as a result, the repressor will bind to the operator and the transcription will be blocked.
When Lactose is present in the environment without glucose then the Catabolite repressor protein will bind to the CAP Site, and lactose will bind to the repressor [regulatory gene product], as a result, the repressor gets deactivated and the transcription takes place.
Lac operon: It is a set of three structural genes z, y, and a which are all transcribed and regulated under one single promoter. The three genes code for β-galactosidase, lactose permease, and transacetylase respectively.
β-galactosidase is responsible for breaking the lactose into glucose and galactose, lactose permease is responsible for transporting lactose across the cell membrane and transacetylase attaches a particular chemical group to target molecules.

1. I think natural selections among the animals are base on their ways or their role in the food chain whether they are predator or a prey. Natural selection is the one you will judge if you are gonna leave or die but it doeasnt mean that here is no way of survival. I think there role in the chain mold them and taught them on how to survive in the wild.
2. The best example of it is when and infant started to grow, so an infant baby's center of sensation is their mouth, if they don't like the taste of it they throw it away until the developments are on the process, they begin to walk then to speak.
3.The behavior of an animal like for example the wolves, they use to be in pact to hunts prey so that they could sure the possible outcome in hunting base on that fact, if a wolf will hunt for its self in a group and fast running dears without a plan the possibility is that the wolf will never catch one
Animal Kingdom. One of the six kingdoms, characteristics include: heterotrophic (obtains energy from eating other organisms), multicellular, eukaryotic and cells have a nucleus but no cell wall or chloroplasts.
Answer:
They are all part of the nervous system.
Explanation:
The brain and the spinal cord are part of the central nervous system and the peripheral nerves are part of the peripheral nervous system. The nervous system works as the communication/ control system of the body. It transmits signals throughout the body.
