Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Providing an exact number for a specific bacterial strain without a range is likely inaccurate due to high inter-individual variability.

◐Partially SupportedBacterial cells are prokaryotic, self-sufficient, and replicate rapidly, unlike eukaryotic human cells.

◐Partially SupportedThe claim that gut microbes outnumber human cells 10:1 is questionable, but the significant number and function of microbes are important.

◐Partially SupportedMicrobes constitute a significant portion of body mass and perform crucial functions.

◐Partially SupportedBacterial cells are independent living organisms capable of replication, genetic modification, and rapid division.

◐Partially SupportedMicrobiome diversity decreases with age.

◐Partially SupportedMicrobiome diversity increases from infancy through early adulthood, peaking when an individual can eat and drink without consequence.

◐Partially SupportedThe Human Microbiome Project was an early observation lacking longitudinal or interventional components.

◐Partially SupportedThe human microbiome varies significantly at the strain level, but functional redundancy is observed when looking across populations.
