|---|---|---|---|---|---|
| atoms | the fundanmental unit of all elements
🗑
|
||||
| organic molecules | all living things and products that are uniquely produced by living things, such as wood, leather and sugar; all chemical compounds or molecules, natural or synthetic, that conatind carbon atoms as an integral part of their molecular structure.
🗑
|
||||
| kinetic | the energy inherent in otion or movement, including molecular movement (heat) and the movement of waves (hence, radiation and therfore light)
🗑
|
||||
| Potential energy | the ablility ot do work that is stored in some chemical or physical state; for exp., gasoline is a form of potential energy because the ablity to do work is stored in the chemical state and is released as the fuel is burned in an engine
🗑
|
||||
| denitrification | the jprocess of reducing oxidized nitrogen compounds present in soil or water back to nitrogen gas in the atmosphere; is a natural process ocnducted by certain bacteria and is now utilized in the treatment of sewage effluents
🗑
|
||||
| synthetic fuels | fuels similar or identical to those that come form crude oil or natural gas. Synfuelsare produced from coal, oil shale, or tar sands.
🗑
|
||||
| inorganic | all things such as air, water, minerals, and metals, that are neither living organisms nor products uniquely produced by living things
🗑
|
||||
| glucose | a simple sugar, the major product of photosynthesis; serves as the basic biulding block for cellulose and starches and as the major "fuel" for the release of energy through cell repiration in both plants and animals
🗑
|
||||
| entropy | degree of disorder; increasing entroy means increasing disorder
🗑
|
||||
| photosynthesis | the chemical process carrried on by green plants through which light energy is used to produce glucose from carbon dioxide and water; oxygen is released as a by-product
🗑
|
||||
| aerobic | with oxygen
🗑
|
||||
| anaerobic | without oxygen
🗑
|
||||
| cell respiration | the chemical process that occurs in all living cells whereby organic compounds are broken down to release energy required for life process.
🗑
|
||||
| nitrogen fixation | the process of chemically converting nirtogen gas form the aire into compounds such as nitrates or ammonia that can be used by plants in building amino acids and other nitrogen-containing organic molecules
🗑
|
||||
| legumes | the group of pod-bearing land plants that is virtually alone in its ability ot fix nitrogen; legumes include such common plants as peas, beans, clovers, alfalfa, and locust trees, but no major cereals grains
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
