What are the four stages of bone formation?
There are four stages in the repair of a broken bone: 1) the formation of hematoma at the break, 2) the formation of a fibrocartilaginous callus, 3) the formation of a bony callus, and 4) remodeling and addition of compact bone.
Is a natural biofilm a pure culture?
A biofilm may consist of a single species embedded in extracellular polymeric substance (EPS), or it may consist of multiple species. The monospecies biofilm does constitute a 'pure' culture, and these do occur under natural circumstances, as for example, H. pylori biofilm in the human stomach (Cole et al (2004) Characterization of Monospecies biofilm formation by Helicobacter pylori," Journal of Bacteriology 186:3124-3132). However, most biofilms that people are familiar with - pipe slime, tooth plaque, etc. - include multiple bacterial species, and can include algae and/or fungus.
How does biofilm work?
A biofilm is a group of microorganisms in which cells stick to each other. The formation of a biofilm begins with the attachment of free-floating microorganisms to a surface. If the colonists are not immediately separated from the surface, they can anchor themselves more permanently using cell adhesion.
What two factors make a biofilm in an intravenous line especially dangerous to the patient?
The two factors that make biofilm in an intravenous line especially dangerous to the patient is infection and the difficulty of treatment. While the microorganisms are within the biofilm, they cannot be eradicated with antibiotics. However, if the biofilm were to detach from the IV line, the access to the circulatory system would potentially cause a massive infection.
What is biofilm?
Biofilm forms when bacteria sticks to surfaces in moist environments by excreting a slimy substance. Examples of this would be the slippery rocks on the bottom of a stream or plaque on teeth.
Why antibiotics induce biofilm formation?
Antibiotics trigger a protective response by bacteria to form biofilms. Bacteria within a biofilm are thousands of times less susceptible to antibiotics than planktonic bacteria

How many stages are in The condensation theory?
There are six different stages in the condensation theory. These include the formation of a nebula cloud, the formation of a sun, the formation of planetesimals, the expulsion of gases from the forming sun, the growth of the planetesimals, and the formation of larger planets from planetesimals.
