You collect trash at the beach and found the following items five plastic bottles, one disposable diaper, large ball of my filament mind, eight plastic bags, decide which of the items you collected could potentially do the most harm to the marine environment?

Answers

If anything, the answer would be the Eight plastic bags. The reason for this is that sea turtles often mistake the plastic bags for jellyfish, which could easily throw the marine environment as well as it's foodchain/foodweb off balance. This could easily wipe the population of the seaturtles as well as it's prey/predators that help maintain the population balance within the marine ecosystem.

Why must all conditions except the independent variable be held constant for all experimental treatments?

Answers

Uhm... I believe you mean a situation when we examine a relation between two variables. In this case all other conditions must remain as constant as possible because they could affect a result and then the conclusions could be false. ie. you examine a relation between temperature and frequency of cell division/organism's activity, then you should stabilize air pressure, food composition, bacterial flora in experimental room... etc. of course when you conduct research in a field, ie. ecological research you can't do any of that but then you are obliged to explain possible aberrations of your results in an article's discussion.
