The main shapes of bacteria are rod-shaped which are called bacillus, spherical called coccus, rigid helical called spirillus, and flexible helical called spirochete. They are found most everywhere, in the human body made of 70 trillion cells there are 700 trillion bacteria. Most …showed first 75 words of 1586 total…

We could also use the same hand to prepare the result and the experiment. We would just use two fingers of the hand for the control and wash the other two for the experiment.
