What is the common link ? The answer is‚ EUTROPHICATION: a complex process which occurs both in fresh and marine waters‚ where excessive development of certain types of algae disturbs the aquatic ecosystems and becomes a threat

necessary for our bodies to make ATP (adenosine triphosphate)‚ which is the energy source used by our cells. Phosphate Analysis 11. After heating‚ a cloudy white solution with white precipitate was the result. 12. Phosphorus forms a wide range of sulfides‚ where phosphorus can be P(V)‚ P(III) or other oxidation states. Most famous is the three-fold symmetric P4S3 used in strike-anywhere matches. P4S10and P4O10 has analogous structures. 13. ATP‚ or Adenosine Triphosphate‚ is a molecule found

Potential energy is the energy of position and kinetic energy is the energy of motion. In order for the ramp to be successful‚ the ramp had to have the right amount of potential and kinetic energy. If you have too much potential energy than the marble would have too much kinetic energy and the marble would not land inside of the target cup‚ it will go right over the top of it. If you have too little potential energy then the marble will not have enough kinetic energy and the marble will not land inside

In this experiment‚ one of the big is osmosis‚ and how it had the overall impact in this excitement a little on osmosis. Osmosis takes place when two solutions of different concentrations are separated by a semi-permeable membrane in which the solvent can pass through but not the solute. In our experiment‚ we used a sucrose solution that will be a hypotonic concentration of solute. This tells us that the solution has a lower concentration of water than does the cells. Therefore‚ due to osmosis‚ the

because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy‚ and then when it hits the ground changes to heat and sound energy‚ and kinetic as it rebounds back up. The higher up the ball is dropped from the more gravitational potential‚ more kinetic energy on the way down and therefore more sound heat and kinetic energy when hitting the ground. The ball will bounce higher the higher dropped from as the energy has to go somewhere

Ex burning of phosphorus‚ sodium in air‚forest fires 7 RAPID COMBUSTION: When a substance burns rapidly ‚on application of heat and produces heat and light it is rapid combustion. Ex burning of petrol‚ LPG 8 SLOW COMBUSTION: When a substance burns in oxygen slowly

Exploration: Water Pollution STANDARDS: SEV1: Students will investigate the flow of energy and cycling of matter within an ecosystem and relate these phenomena to human society. SEV 1a: Interpret biogeochemical cycles including hydrologic‚ nitrogen‚ phosphorus‚ oxygen‚ and carbon cycles. Recognize that energy is not recycled in ecosystems. SEV5: Students will recognize that human beings are part of the global ecosystem and will evaluate the effects of human activities and technology on ecosystems. SEV5c:
