Sleep enables our brains and bodies to rest‚ equipping us to take on the next day. A normal sleep cycle consists of 5 stages‚ 1‚ 2‚ 3‚ 4‚ and REM. If sleep is disturbed it can cause problems with health and everyday life. Stage 1 is when sleep is light and one can be awakened easily. In this stage we begin to drift in and out of sleep‚ the eyes move slow and muscle activity slows. Stage 1 lasts about five minutes and is followed by stage 2. Stage 2 eye movement stops and brain waves become slower

S1 Jan 2001 1) The students in a class were each asked to write down how many CDs they owned. The student with the least number of CDs had 14 and all but one of the others owned 60 or fewer. The remaining student owned 65. The quartiles for the class were 30‚ 34 and 42 respectively. Outliers are defined to be any values outside the limits of 1.5(Q3 – Q1) below the lower quartile or above the upper quartile. On graph paper draw a box plot to represent these data‚ indicating clearly any outliers

There are quite a few variations between normal and tumor cell division. Normal cell division can be broken into four phases: G1‚ S‚ G2‚ and M. During the G1 phase‚ RNAs are produced‚ proteins are synthesized and through the P53 gene (also known as the “Guardian of the Genome”)‚ cells are checked for damage and those that are found are forced to go through apoptosis where the cells are forced to “commit suicide” to prevent replication. Through the S phase‚ the DNA is duplicated and in the G2 phase
