- 4721: Phosphates in Water Pollution
- ... masses of algae's blooms, choking rivers and lakes. Phosphorus compounds act as a fertilizer for all plant life, whether free-floating algae or more substantial rooted weeds, and are implicated in eutrophication. Many countries control phosphate levels, whereas Switzerland has banned the use of phosphates. The marine environment is both fragile and more resistant than the terrestrial ecosystem. It is fragile for the reasons that nutrients are generally present in ...

- 4723: Involvement of K+ in Leaf Movements During Suntracking
- ... the light. In this study, the diheliotropic movements of C. pallida are examined. The purpose of this experiment is to determine which ions, if any, are used by pulvini cells of Crotalaria pallida Aiton to control the uptake of water, thereby affecting diheliotropic movement. As mentioned before, most studies investigating the mechanisms of leaf movement have been performed on nyctinastic plants. These plants respond to light and dark changes, not direction ...
- 4724: Insulation
- ... does is fill the inside of five, gallon-sized Ziplock bags with the insulation material so it is one centimeters thick all around. Leave the sixth Ziplock bag empty because it will serve as the control group. Then fasten the insulating materials to the inside of the gallon sized Ziplock bag with adhesive tape.

- 4726: Analytical Chemistry
- ... on samples of the patient's blood and other fluids. Modern industrial chemical plants rely heavily on quantitative analyses of raw materials, intermediates, and final products to ensure product quality and provide information for process control. In addition, chemical analyses are essential to research in all areas of chemistry as well as such related sciences as biology and geology.
- 4727: Biology
- ... fishes digestive tract. In their case when the oxygen level in the water they were in was low they could still collect oxygen by breathing. After time these sac-like lungs became swim bladders that control the up and down motion of a fish. 12. The reptiles most helpful advancement in reproduction that helped them live on land was the use of internal fertilization and the ability to lay eggs that ...
- 4728: Solving the Mystery of the Romanovs
- ... separate from the cells nuclear genome. This genome contains only 27 genes, involved in the process of oxidative phosphorylation. Yet there is a noncoding region about 1,100 nucleotides long. This region contains signals that control the replication of the chromosome and the transcription of the mitochondria genes. This DNA sequence accumulates mutations ten times the rate of the nuclear DNA. This high mutation rate results in unique patters of single ...

He began experimenting on how to control the substance. He wanted something that could absorb the nitroglycerin and not still have the same power. He Found that a substance called Kieselguhr. This substance consisted of (diatomeus earth) marine organisms diatoms. This way ...
