THE AQUATIC BIOME:
The aquatic biome is broken down into two basic regions: freshwater and saltwater. The
temperature of the aquatic biome varies for season to season. Freshwater regions include
wetlands, rivers, lakes, ponds, streams, etc. Saltwater regi

alThe oxidation of glucose to carbon dioxide releases approximately 277.4kcal of
energy. If all of this energy is released at one time, then most of it would be lost as heat.
Burning the energy all at once would be akin to igniting your gas tank in order

b. I predict that the 0% NaCl solution will not produce any concentration of NaCl outside
of the bag because there is no solute. Additionally, because the they have equal
concentrations, water can go back an

The pH graph is expected to reach its maximum reaction rate at a pH of about
7. This is because the optimal pH for most enzymes to function in is within the range of
6-8 (mostly neutral). The pH of a substance reflects its acidity, or concentration of H i
What on Earth is Going On Here, Anyway?
NetReaction:Energy (light) + 6CO2 + 12H2O - Glucose (C6H12O6) + 6H2O + 6O2
b) The control of the experiment is the light, unboiled chloroplast suspension. This is
because, in nature, that is what naturally occurs. In the other experiments, you are
changing one variable from the control to test the different effects.

4. Cells and Energy
CHEMICAL ENERGYChemical energy is cellular ATP in organisms.
Chemical energy releases energy used for cell processes.
PHOTOSYNTHESISPhotosynthesis has light independent reaction which uses CO2.
Photosynthesis has light dependent reacti
5. Cell growth and division
THE CELL CYCLEThe cell cycle is a regular pattern in eukaryotes.
The cell cycle consists of mitosis, which is a division of cell nuclear contents.
MITOSISMitosis starts with condensing of chromosomes, which are DNA strands that
3. Cell Structure and function:
CELL THEORYThe cell theory says all existing cells are produced by other living cells.
The cell theory says all organisms are made of cells that contain organelles, which
perform special jobs.
