Question

an experiment is designed to see if the shells of sea snails are weakened by exposure to sea water which is more acidic than normal. shells are placed in normal sea water, sea water that is more acidic than normal, and sea water that is more basic than normal. the shells are checked every day at 8 am. which of the following is the best hypothesis for this experiment? the shells in the normal sea water will be the strongest. if the shells are exposed to sea water that is more acidic than normal, then they will be weaker. the shells in the sea water that is more basic than normal will be stronger. if the shells are affected by the level of acidity, then they will be weaker.

Answer 1

Since the statement of the problem is to determine if levels of acidity in sea water affect the strength of a sea snail's shell, then the best statement of hypothesis should be:

" if the shells are affected by the level of acidity, then they will be weaker."

That hypothesis refers directly to the theory being questions in the problem.
