Common mistakes
Common mistakes
- Believing that all microbes are harmful. Many are useful and are used in making food and medicine.
- Believing that antibiotics treat colds and flu. Antibiotics kill bacteria and have no effect on viruses.
- Confusing yeast with bacteria. Yeast is a fungus, and it has a true nucleus.
- Calculating binary fission incorrectly. The number doubles at each division, so it is calculated as a power of 2, not by addition.
