In mammalian brain anatomy, the prefrontal cortex (PFC) is the cerebral cortex which covers the front part of the frontal lobe.The PFC contains Brodmann areas 9, 10, 11, 12, 46, and 47. third definition of the prefrontal cortex is the area of frontal cortex whose electrical stimulation does not lead to observable movements. For example, in 1890 David Ferrier used the term in this sense.
The blubber helps to keep them warm since they live in a very cold environment.   When harp seals are born, they have a white â¦ fur coat. The fur coat camouflages into the snow to protect them from their enemies on land.
The Staphylococcus bacteria, or Staph, can survive for as little as a few hours to as long as many months! Hard surfaces that are cleaned are less likely to harbor bacteria, but porous surfaces like towels and sponges are perfect breeding grounds for bacteria. Humidity is also a factor, if it's lower then 10% then bacteria will not be able to survive on a dry surface for long. It's important to keep areas clean because any kind of nutrient (food crumbs, skin cells, droplets from a sneeze) helps them live. Wednesday, February 01 2012.
