What diseases can a CT scan detect? A bowel perforation consists of a hole that runs all the way through the bowel or large intestine. The danger is that perforation can cause peritonitis, an inflammation of the membrane lining the entire abdominal cavity. If acid from the stomach, bile or bacteria enters the cavity, then peritonitis can take place -- a life-threatening condition.
The statement that a prion is an infectious, self-reproducing protein structure is true. Prion is short for short for proteinaceous infectious particle. All known prion diseases in mammals affect the structure of the brain or other neural tissue. Hope this answers the question. Comments.
The main types of nucleons are protons and neutrons. A proton, as it's name suggests, has a positive electric charge, and a neutron has a neutral electric charge (meaning that it has no charge). The two in the nucleus of the atom make a positive charge, since the neutron has no charge at all.
