Answer:
very few M. tuberculosis in the standard nutrient cell cultures carry the rpoB gene mutation, but almost all of the M. tuberculosis in the cell cultures with rifampin carry the rpoB mutation
Fossils could not be found in that layer of rock
A
addition mutationadeition mutation
so its A
Answer:
The lack of ATP would slow nerve responses to generate an action potential
Explanation:
Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.
