Urea Is Highly Soluble in Water and Readily Diffuses Across

question 39

Essay

Urea is highly soluble in water and readily diffuses across cells, but uric acid is relatively insoluble in water and does not readily diffuse across cell membranes. If ruminants excreted their nitrogenous wastes as uric acid, how might that affect the benefits that symbiotic microbes provide to them?
