Typically the joints where the spine joins the pelvis are also affected. Occasionally other joints such as the shoulders or hips are involved. Eye and bowel problems may also occur.
The allotropes of carbon. Three forms (or 'allotropes') of pure carbon are diamond, graphite and buckminster fullerene (or 'buckyballs'). In all three allotropes the carbon atoms are joined by strong covalent bonds but in such different arrangements that the properties of the allotropes are very different.he allotropes of carbon.

Organic compounds contain carbon in them (although there are also inorganic carbon compounds of course). So all salt is inorganic. That does not mean your body does not use salt. In fact, salt is critical to brain function, the cell function known as osmosis, blood presure, etc.inerals can contain anything (nearly), including Iron, Magnesium, Silicon, Oxygen, Fluorine, Carbon an â¦ d Hydrogen. Inorganic means that it does not contain material derived from life processes.
