Research : Utah Reported Crime Statistics. Index crimes include murder, rape, robbery, aggravated assault, burglary, larceny, motor vehicle theft, and arson. Utah's total index crime rate in 2005 was 4,096, a 5.2% decrease over the 2004 rate of 4,322. Utah's rate has paralleled the national rate over the past 40 years.
Exocytosis. Exocytosis is the reverse of endocytosis. Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules. By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.
1 The outward movement of positive potassium ions makes the inside of the membrane more negative and returns the membrane toward the resting membrane potential (repolarizes the cell). 2  When the membrane potential returns to the resting value, the potassium channels shut down and potassium ions can no longer leave the cell. As we discussed, the inside of the cell is slightly negatively charged (resting membrane potential of -70 to -80 mV). 2  A disturbance (mechanical, electrical, or sometimes chemical) causes a few sodium channels in a small portion of the membrane to open.
