Answer:
It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.
Explanation:
When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.
Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.

Answer:
they use to live
Explanation:
As they breath out carbon dioxide the plants take in the carbon dioxide and make air with it. Animals also use air to do their day to day things like eat.
Explanation:
Hey, there!
The eco-system consists of various type of organisms in tge ecosystem. The all type of organism as producer, decomposer, consumers live in ecosystem.
Three adaptations of organism are:
- By losing and gaining of organs: Some of the animals lose their organs to survive in some places like yak have more hair to survive in cold places.
- By changing the colour of body: Some animals such as grasshopper changes their colour to survive in places.
- By modification of organs: some animals modify their organs to survive such as legs and beak of ducks are modified to survive in swim and search foods.
The importance of adaptation are:
- It helps organism to live a longer life.
- The adaptation helps to make an organism fittest to any environment.
- The adaptation helps an organism to search foods and live their life.
