The reason you aren't receiving responses from the science teachers among us is that you haven't tried to answer these questions and tell why you think it's that answer. Please remember that teachers here won't do your homework for you, but will be happy to give you feedback to help you learn and do your own work.

Please re-post for each question, stating what you think the answer is and why.

Thanks.
