Which of the following is a characteristics of a bacteria except _______?

The characteristic of bacteria that does not fit with the others listed is "they do not cause disease." Bacteria are unicellular microorganisms that can be seen under a microscope. They vary in size, but most range from 0.5 µm to 5 µm in diameter. Bacteria can be grouped according to their cell shape, which can be cocci (spherical), bacilli (rod-shaped), or spirilla (spiral-shaped). While some bacteria can cause disease, not all bacteria are harmful. In fact, many types of bacteria are beneficial and essential for human and environmental health. For example, some bacteria help with digestion, while others are used to break down waste materials. Therefore, it is incorrect to assume that all bacteria are disease-causing organisms.
