I've got an Indian Biology teacher and what he teaches doesn't match with the answers in this website. And this puts me into a vast confusion. So, should I finalise that the information provided in this website are 100% correct?

I have looked at the quiz and corrected the answers to question 8 and 10 for the user. Hopefully this corrects the confusion. Well done to those students who spotted the errors.
