Critically evaluate the claim that offender profiling is “more of an art than a science”. Criminal profiling attempts to understand the characteristics and personality of an offender and has now gained recognition as a useful investigative tool. To be able to use profiling effectively you must be able to understand the categories of violent and sexual crimes and how they are described within convictions within court. Holmes 1989 stated that profiling is more helpful when there is a sadistic element

cellular respiration is taking place at the same time‚ consuming oxygen‚ the rate of which the discs rise is an indirect measurement of the net rate of photosynthesis. Aim: To find out if light affects the rate of photosynthesis through an investigation with leaf discs of a spinach leaf. Hypothesis: If the light source is removed or becomes limited‚ then it will take much longer for the leaf disc to rise as cellular respiration will no longer be taking place as part of the equation for photosynthesis

these results as I believe the more Magnesium there is the more Oxygen it will take on to form the Magnesium Oxide and so believe the results should gradually get heavier and heavier as the Magnesium gets heavier and heavier. The equation for this investigation would be Mg + O2 MgO which would balance as 2Mg + O2 2MgO. This is done as the Oxygen has two molecules which would need two Magnesium molecules to balance it out.
