Thanks for this. Taking Bio 101 at my school, even though it isn't required, but the Adviser said it would be an easy class to take to get ready for human anatomy which I have to take in the fall if I'm accepted into the program I want. Yeah, it's anything but easy. I'm really having a hard time.

answers of the review
1) Carbon is the basic building block of life . This is the reason carbon dating is effective, all living organisms contain carbon. Also, carbon is so important to life because virtually all molecules in the body contain carbon. For this reason it can form long chain molecules, each with different properties.
2)
polymers form through a condensation reaction which links monemers together to form polymers.
polymers break down through hydrolysis which is when u take a polymer and add water to the bond and u end up breaking down polymers.
3) carbohydrates: carbon, hydrogen, oxygen
function: store energy, provide structural support
lipids: carbon, hydrogen, oxygen
function: store energy, provide barriers
proteins: carbon, hydrogen, oxygen, nitrogen
function: transport substances, speed reactions, provide structural support, make hormones
nucleic acids: carbon, hydrogen, oxygen, nitrogen, phosphurus
function: store and communicate genetic info
