🔬 Science Element
Las bacterias son organismos vivos unicelulares diminutos. Millones de ellas caben en la punta de tu dedo. La mayoría son inofensivas y muchas son útiles, pero algunas pueden echar a perder la comida o enfermar a las personas. Las bacterias se reproducen por fisión binaria. Los antibióticos tratan infecciones bacterianas pero no funcionan contra virus.
