Can anyone explain and expand my knowledge on these questions? Totally new to biology and got exams in a few weeks. Like just starting today new and got exams in about a months time. Redoing my final's exam as I was going towards law and decided to go into science. So this is the second term exams and I have only 1 month to learn all of biology and chemistry. Can anyone elaborate and explain more on this for a new totally fresh starting biology student? Thanks. Pictures of the paper : http://i.imgur.com/XCkD8OA.jpg http://i.imgur.com/MKbAoOj.jpg
