Tuberculosis is caused by bacteria. Specifically, the bacterium Mycobacterium tuberculosis is responsible for the disease, which primarily affects the lungs but can also impact other parts of the body.
Leghemoglobin functions in nitrogen fixation by absorbing oxygen. It creates a low-oxygen environment in the root nodules, which is necessary for the nitrogen-fixing enzyme nitrogenase to function effectively and fix atmospheric nitrogen.
Beans are helpful in nitrogen fixation. They form symbiotic relationships with nitrogen-fixing bacteria in their root nodules, converting atmospheric nitrogen into a form usable by the plant and enriching the soil.
If one bacterial cell divides every 20 minutes, it will divide six times in two hours (120 minutes). Since each division doubles the number of bacteria, the original cell will result in 2 power 6 = 64 bacteria. Therefore, the ...
