The most important difference between primary cells and secondary cells is Select only the best primary cells exhibit a reduction in potential as they run down secondary cells have more than two working electrodes only primary cells have a salt bridge secondary cells are rechargeable primary cells use chemical energy directly, while secondary cells convert energy to work before producing electricity

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.
