Answer:
The CRA-cAMP complex increases the rate of expression of lac operon when glucose is absent and lactose is present as nutrient.
Explanation:
CRP is the catabolite gene activator protein that forms a complex with cAMP. The CRP-cAMP complex facilitates the binding of RNA polymerase to the promoter region of the lac operon. This robust binding as stimulated by CRP-cAMP complex is followed by the formation of open complex and initiation of gene expression.
Hence, the CRP-cAMP complex positively regulates the lac operon and increases its expression when glucose is not present.
Pedialyte is an electrolyte solution which is taken orally. Originally it was given to children, but recently it has become popular as the cure for hangover. This has led to it's increased use in the adults. However, it should be noted that this solution is rich in potassium and sodium content. This poses a threat to the patients suffering from high blood pressure and kidney disorders. Such individuals should avoid excessive intake of pedialyte.
Carbs contain lots of energy, so not A.
They are different carbs with different atom arrangements, so not B.
And carbs only contain 3 elements C, H, and O.
So the answer should be C.
