Please take note there might be some spelling issues since I'm used to American English
for example

Grey - Gray

Color - Colour

Organisation - organization

Burette - Buret

I try to make all my scientific spelling 100% accurate, but will mostly use American English in other Occasions.(If you find out any other mistakes while doing the paper please inform me I'll correct it, thank, you!... and re-upload)

In some instances spelling differences occur in technical/biological words too, normally in an instance like this it's OK to spell either way, for example..

fiber - fibre

hemoglobin -heamoglobin
