Question

ninety percent of the cells in the human body are microbes—mostly prokaryotes and some microscopic eukaryotes. which statement about human microbiomes is true? uniform communities of well - characterized bacterial species cover every surface of the human body. diseases in which our immune systems begin to attack our bodies have been linked increasingly to the changing diversity and composition of our microbiomes. biofilms produced by human microbiomes are always beneficial to their hosts. human health depends on ridding the body of all microbes, both on the inside of the body and on the outside. human microbiomes are composed primarily of prokaryotic extremophiles.

Explanation:

• Human microbiomes are diverse communities of microbes. They are not primarily prokaryotic extremophiles (A is false). Human health depends on a balanced microbiome, not ridding the body of all microbes (B is false). Biofilms are not always beneficial (C is false). Diseases are linked to changes in microbiome diversity and composition.

Answer:

D. Diseases in which our immune systems begin to attack our bodies have been increasingly linked to the changing diversity and composition of our microbiomes.
