Answer:
Twenty-eight (28) bacteria
Explanation:
Binary fission involves the production of 2 cells from a single cell.
At the beginning of reproduction, there were seven bacteria and binary fission takes place every two hours.
At the end of the first two hours, each of the seven bacteria would have divided into two to make a total of fourteen bacteria.
AT the end of the second two hours (making four hours now), each of the fourteen bacteria will divide into two to give a total of twenty-eight bacteria.
<em>Hence, there will be a total of twenty-eight (28) bacteria after four hours.</em>
