Carbohydrates / energy, plant structure / bread, rice, grain, pasta
Protein / transport, speed up reaction, structure / enzymes, hormones, skin, hair, muscles
Lipids / barrier, energy / oil, wax fat
Nucleic Acid / genetic information / DNA

2. monomer is one unit (example, monosaccharide), polymer is made up of many monomers put together.

3. product (the end product of a chemical reaction, what you make), reactants (starting molecules)

4. proteins

5. 75

6. 65

7. enzymes lower the activation energy. less energy is needed to for reaction to occur.

8. positive

9. active site changes shape, can no longer bind to the substrate

10. a. hydrogen peroxide

b. catalase (enzyme in living cells)

c. hydrogen peroxide

d. water, oxygen gas

The following link is a great resource in regards to the effects of global warming.

This is the link I showed on Monday that displays the relative size of different things. Enjoy!

Benefit
Benefit, Not harmed, does not benefit
benefits, harmed
ex. 1 - eyelash mites and humans, ex.2 - whale and barnacles, ex 3 - sea cucumber and pearlfish
a. Birth b. Death c. Emigration d. Immigration
emigrated, immigrated
Other squirrels in the community would have more competition for food; Animals that prey on squirrels will grow in population because they have more food; Producers that are eaten by squirrels will decrease in number
Phosphorous, Carbon, Water, Nitrogen
Bacteria
When organisms die and decompose; Urine
Organisms that have died many years ago.
Sun, Wind, Food, Water
Coal, Oil, Natural Gas
We started using coal and oil to produce more energy. More energy --> more food --> Increase in population
Agriculture, Urban Development, Hunting and Gathering
Rarely does being "green" pay off. Often times it comes at a personal cost. Human nature tends to only care about their own well being.
Global warming occurs when the atmosphere is thickened by the carbon emissions released by human activity. The thickening of the atmosphere causes more of the sun's heat to be trapped which leads to increased global temperature.
Primary succession - predictable changes in an ecosystem that starts from bare rock. Secondary succesion - predictable changes in an ecosystem that begins after the original community has been cleared. Starts with soil.
