| Osmosis and diffusion is called passive transport because it takes no energy to move from a high concentration to a low concentration. |
| Ferrous sulfate compared with iron polysaccharide complex resulted in a greater increase in hemoglobin concentration at 12 weeks. |
| It is also demonstrated that a high polysaccharide concentration and short reaction time are adverse to nHA crystals. |
| In most cases, such concentrations of atoms are so rarefied that the chances of colliding are infinitesimal. |
| High concentrations of a variety of metal ion complexes are known to be harmful because of their toxic and genotoxic effects. |
| Dangerous concentrations can be released by agitation of stored liquid manure. |
