.... up with something to substitute for plastic. The person who comes up with the solution will become and instant millionaire and everyone will be happy. There is one draw back of this way of solving problems, I mean sure it's great to wait until the demand but we should still learn from our mistakes. We should learn to plan ahead and see what the consequences could possibly be. We still have other demands to meet, there are three major demands of fossil fuels and they are heating, transportation, and industry. Although transportation is taken care of, we may not like the .....

.... and, lasts hours. With female octopuses receiving spermatophore up to 1m long. Female octopus seem to prefer larger males as mates and male octopus may mate with more than one female in their life span, however the male octopus only lives a few months after breeding, and the female will die shortly after the eggs hatch. Incubation can take from 150 days to seven or more months. The female may produce any where from 20,000 to 100,000 eggs over a period of several days. During incubation the female octopus will take to cleaning and aerating the eggs. This takes place at .....

.... transformed into a two-carbon compound called an acetyl group. The two acetyl groups combine with a molecule of coenzyme A each to form two acetyl coenzyme A molecules. These molecules are processed in a complex pathway called the Krebs cycle. As the Krebs cycle progresses through both pyruvic acid molecules, six molecules of NADH, two molecules of ATP, and additional carbon dioxide are all formed. FAD picks up a hydrogen atom from each pyruvic acid molecule, and a total of 2 FAD2 are formed. NADH and FAD2 transport their hydrogen atoms and electrons to the electron trans .....

.... the following: „h Acting before thinking - this may lead to failing academically or friction in social relationships. „h Difficulty in waiting turns, interrupting or intruding on conversations/games. Examples of hyperactivity will be seen through the child often fidgeting or squirming in their seats. The will be described as being "on the go" or acting as if "driven by a motor". Many other symptoms like quick shifts of moods temper outbursts, and problems with getting along with others also occur often. Unfortunately, most of the disorders features are negative. Child .....

.... of a frog muscle, Overton found some interesting results. He observed that lipophilic molecules (molecules attracted to fat solvents) could easily cross this cell membrane, however larger lipid insoluble molecules could not. He also observed that small polar molecules could slowly cross the membrane. Other experiments with the likes of hen eggs suggested the presence of a lipid layer in the membrane. These results became known to biologists across the world and it was generally accepted that a semi-permeable lipid membrane surrounded some if not all cells (2). Although this .....

.... ore. However, a huge untapped source is our oceans. Sea water contains 3.3x10^(-9) (3.3 parts per billion) of uranium, so the 1.4x10^18 tons of sea water contains 4.6x10^9 tons of uranium. All the world's electricity usage, 650GWe could therefore be supplied by the uranium in sea water for 7 million years(Energy 25). This is a only a theoretical number because it is not possible to get all of the uranium out of our vast oceans. Also, it does not include the fact that in that many years, half of the uranium will no longer exist due to radioactive decay. So, at worst, we wo .....

.... is exhibited through a process called guttation. Through guttation, tiny droplets of water are sometimes forced out of some plants. Guttation only works when soil is almost completely saturated with water and leaves are not losing much water through evaporation. When the xylem is full of water, the molecules will not move back down the structure, but rather need to be expelled from the plant. They will move, by the process of osmosis, to an areas where there is the least amount of pressure. These areas are usually openings located on plant leaves. Once the water molecules re .....

.... circulation. Wind-driven circulation result from the wind sets the surface waters into motion as currents. The currents generally flow horizontally-that is parallel to the earth¡¦s surface. The wind mainly affects only the upper 100 to 200 meters of water. However, the flow of wind-driven currents may extend to depths of 1,000 meters or more. Thermohaline circulation produces great vertical currents' hat flow from the surface to the ocean bottom and back. The currents largely result from differences in water temperature and salinity. The currents move sluggishly from the po .....
