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.
Huh? Lol I don’t get the question
Answer:
for the first question the answer is cell. And the second questiob the answer is energy
Fermentation
The electron transport chain gives off 32 ATP the kreb cycle gives off 2 and so does glycolysis. Fermentation happens in muscles or alcohol
I think the answer is ozone i hope i am right and hope this helps
