Give one reason documentation is important in forensic science.

On the blank sheet of paper provided, calculate and complete the following serial dilutions created. A stock solution with an initial concentration of 200.2ng/ was used to start the series. Now calculate the volume of solute, and the volume of solvent needed to create each solution tube in the following dilution series. Show all you’re your work and do not forget your units!   Tube Volume of final solution Concentration of final solution 1 43.6l 163.5ng/l 2 67.8 83.9ng/ 3 96.1 62.0ng/ 4 157 8.6ng/  

Briefly, describe the proper method of decontaminating your work area, before starting and after completing an experiment.

What is the color observed in a sample positive for urine, as discussed in class?

The ____________ pipetting method is the name of the pipetting technique used in the lab. 

was the name of the presumptive test for seminal fluid, conducted during our lab session, that gave a final blue color during a positive reaction . Using only the acronym is acceptable.

The phenolphthalein test mentioned in question 14 is 

is the substance that is present in a urine sample, that causes a positive color change to occur during testing?

Calculate the following simple dilution. Keep your units and do not round until you get your final answer. There was a stock solution of concentration 325ng/ul and volume of 2521ul. If the concentration of the final solution was 102.3ng/ul, what is the volume of water in ul, used to make the diluted solution? M1 or C1= M2 or C2= V1= V2= Volume of Water=

Give four (4) examples of serological fluids that are tested in Forensic Science.
