| Unlike staphylococci, which tend to cause localised infections such as abscesses, streptococci are essentially organisms that spread. |
| The organisms also produce organic compounds such as lactic acid, hydrogen peroxide and acetic acid. |
| Recent research around volcanic vents has found tiny organisms that breathe iron. |
| Suffice it to say, different minerals weather and grow at different rates within higher organisms, just as they do in the ambient environment. |
| The adaptation of organisms to their habitat ultimately depends upon environmental criteria. |
| These findings illustrate that a prokaryote possesses a signal trafficking system with features common to those used by higher organisms. |
