As to your answer to the experiment of testing the effectiveness of a rubbing alcohol in killing bacteria http://www.scienceline.ucsb.edu/search/DB/show_question.php?key=1310071505&task=category&method=&form_keywords=&form_category=chemistry&start=, which one should fall apart first? And why?
Answer 1:

Bacteria help things like tomatoes to rot or breakdown. If you have two similar very fresh veggies and place one in a jar filled with water, and one veggie in a jar full of rubbing alcohol, the one that rots first had more bacteria on it. If one solution is better at killing bacteria there will be less bacteria and the veggie should last longer. You get do do the experiment to find out if water or rubbing alcohol kills more bacteria.
