It is incredible to me how many people absolutely discount it...or say, "its 'only' a theory"..in public school texts books it is glossed over...if you read peoples answers regarding evolution, they just dont grasp the main points of it....really, I taught HS Biology for 15 years...do we just ignore the religious zealots who try to introduce intelligent design or creation science into public schools....also...it seems that many people say they grasp its salient points on this website, but most people I know are very religious and believe in creation....I think it is important that people learn biology....any ideas as to how to educate the masses or is it not our responsibility or are they hopeless??

What acid turns the indicator yellow on an OF test?

I'm not sure, I think it's citric acid since it is produced during the
