Question

1) Bacteria
2) Viruses
3) Fungi
4) Protozoa
5) All of the above

Answer 1

Bacteria in the human body have helpful functions, such as aiding in digestion and competing with harmful pathogens to maintain a healthy microbiota.

Step-by-step explanation:

The question asked which microorganisms have a helpful function in the human body. The correct answer is bacteria. This is because certain bacteria in the human body perform beneficial roles, such as aiding digestion and synthesizing important nutrients like vitamin K in the gut. Some bacteria also compete with harmful pathogens and maintain a healthy balance of our microbiota. Microorganisms like viruses, fungi, and protozoa can be pathogenic, although it's noteworthy that not all fungi and protozoa are harmful, and some can have neutral or beneficial interactions with their hosts. However, when talking about helpful microorganisms in context of health, bacteria would be the primary candidate among those listed.
