alexandria asks:

i have been asked to carry out the p skill for my coursework which is on the aspects that affect the growth rate of plants. i am not sure what i am supposed to write about.
before we were handed this task we were asked to make barium chloride. i'm not sure if this is meant to be counted as as aspect that affects the growth rate of plants or not. i cant find any information on this coursework. please help!!!!!

etutor answers:
