oh well sorry you should've made yourself more clear. I don't see any reason why you can't use the same answers except the one's that specifically ask why you're interested in their work. Don't feel guilty if you're not sure, because no one can expect you to know 100% that that type of research is for you if you haven't done anything in it. One thing you should know is that if the labs are in the same building right next to each other you can expect them to talk a little bit. In that case, it would probably be better if you copied your answers, b/c at least you seem consistent haha. Don't get caught saying how much you love microbiology and then have research professor find out you wrote one loving neurobiology. Just be honest and say that you want to be involved in research to get your feet wet. If there's one you particularly want to get into, then it's probably okay to express that that's the one you particularly want to do.
