Answer:
The correct answer is B high levels of lactose and high levels of cyclic AMP.
Explanation:
Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.
Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.
On the other hand cyclic AMP is a positive regulator of lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.
The answer for the above question is Cardiovascular fitness. It is the ability of the heart, lungs, and blood vessels to function efficiently when a person exercises. Cardiovascular system is the body system that includes the heart, blood vessels, and blood, and functions by transporting oxygen and nutrients to body cells and removing cellular wastes. Cardiovascular endurance on the other hand is the ability of the body to work continuously for extended periods of time.
