You begin an experiment with two populations of E. coli that are each composed of 100 cells. The cells are all genetically identical (i. e., they are clones). You grow these populations in flasks on a lab bench under identical conditions with sufficient resources for the survival of all individuals. What process will introduce genetic variation into these populations?

What's the waste product of electrons and pyruvate combining in fermentation?

After frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.
