after learning the local water supply you decide you want to start doing some research you decide to measure the phosphate levals of your local pond every week and record the results . what is the best reason to carry out this process ?

Ibelieve the answer is a-broad because that is a leafed plant.

It might. it might because if you think about if they discovered if we came from (lets say something funny like aliens) and thy found cells that matched and they would have t do more research about it but would most probably change their theory.
