 Alternative "clean" energy sources | wind farms, solar panels, biomass, and geothermal |
| the orange and yellow sunsets we see are caused by | the sun's light passing through a greater thickness of atmosphere and scattering |
| the sky looks blue during the day because | molecules of white light are scattered and we see blue |
| renewable resource | resources that can easily be replaced like trees and geothermal energy |
| natural and nonrenewable resources | minerals, coal, oil, and natural gas |
| ozone depletion | severe sun burns, skin cancer, death of plankton, eye problems |
| global warming | more hurricanes, drought, immune system problems |
| biodiversity | a richness of the of the different kinds of living things in an area |
| What is ozone depletion and what causes it? Can this be stopped or reversed? How? | Ozone depletion is the thining of the Ozone layer. The CFC in spray cans, air conditoners, and electrical cleaners cause Ozone depletion. It can be stopped by stopping the use of CFC. |

| convection | transfer of heat through a fluid |
| precipitation | liquid water falling as rain, sleet, hail, or snow |
| condensation | the process by which molecules of water vapor in the air become liquid water |
| conduction | direct transfer of heat by touching |
| evaporation | the process by which liquid water escapes into the air as water vapor |
| radiation | direct transfer of heat through open space |
| global winds and areas of no wind | polar esterlies, prevailing westerlies, trade winds, hores latitudes, and doldrums |
| clouds | cumulus, cirrus, and stratus |
| phases of the cell cycle | interphase, (beginning) prophase, metaphase, anaphase, telophase, (mitosis) and cytokinesis (end) |
| formula for photosynthesis | carbon dioxide+water [light energy, chloraphyll] = glucose+oxygen |
| 3 ways to prevent cancer | don't smoke, eat healthy food, and wear sun screen when in the sun |
| 4 ways to treat cancer | radiation, surgery,chemtherapy, and gold nanodots |
| pair this - ATATCGTATCGGCT | TATAGCATAGCCGA |
| parts of chromosome | centromere (middle), coiled chromatin, and chromatids (symetrical "legs" of coiled chromatin) |
| parts of a compound microscope | eye piece (also eye piece lens and ocular) , nose piece, stage, low and high power objective lens, light source, condenser (also diaphragm and aperature control) , base, fine and coarse adjustment knob, spring clips, arm, revolving nose piece, and body tube |
