Unit 3 Section D Summary HW Problems Pt. 1

#1:
Large organic molecules found in living systems.

#2:
a. Coal, petroleum, natural gas, nuclear fission
b. Natural gas
c. Nuclear fission

#3:
Biomass, hydropower, coal.

#4:
Macromolecules like lipids, carbohydrates and proteins.

#5:
Petroleum is used for fuel, and in its raw form, to make all kinds of everyday objects like sports equipment and CDs.

#17:
a. Burning of fossil fuels, respiration.
b. Forests, ocean
c. Running would increase your amount of CO2

#18:
A carbon dioxide starts in the atmosphere and moves to the biosphere to be altered by a plant.  Then, the plant decays into the ground and seeps into water below the surface of the Earth, ending up in the ocean.

#19:
6CO2 + 6H2O --> C6H12O6 + 6O2, C6H12O6 + 6O2 --> 6CO2 + 6H2O

#20:
a. Increase of H2O increases with CO2 as more respiration occurs
b. It would counteract the predicted behavior of global warming because the water vapor would cool the air, but still not Earth's temperature.
