Verified step by step guidance

1. Step 1: Understand the term 'transient microbiota' by breaking down the phrase. 'Transient' implies something temporary or short-lived.
2. Step 2: Recall that microbiota refers to the community of microorganisms living in or on the human body.
3. Step 3: Differentiate transient microbiota from resident microbiota. Resident microbiota are permanently established and often beneficial, while transient microbiota are temporary and do not permanently colonize the host.
4. Step 4: Recognize that transient microbiota can be present for a short time but are eventually removed by the host's immune system or other factors.
5. Step 5: Conclude that the best description of transient microbiota is 'Microorganisms that are present in the body for a short period and do not permanently colonize the host.'
