Erica Mitchell Mr. Vredenburgh Period 5 52/55 The Effect of Carbon Dioxide on Salt Water Abstract Background: The human population strongly relies on the oceans for food‚ transportation‚ recreation‚ climate regulation‚ and half of the Earth’s oxygen. These oceans‚ that we rely so heavily on‚ are becoming more acidic and less hospitable‚ making ocean acidification the world’s second most important atmospheric carbon problem. This carbon is released into the atmosphere by burning fossil fuels

PLAN OF INVESTIGATION Fundamental Science Salt water egg experiment Result Some objects float on top of the ocean‚ and other objects sink to the bottom. Why? In this salt water egg experiment we can find a solution for this question. It was noted that to make the egg float salt is needed to dissolve into fresh water. When the egg was lowered into the fresh water container it started to sink. But when salt was added to the container the egg started to float. Adding salt

Fresh Water Cooling System Introduction Although there is an abundance of free sea water available‚ marine diesel engines do not use it directly to keep the hottest parts of the engine cool. This is because of the corrosion which would be caused in the cooling water spaces‚ and the salts which would be deposited on the cooling surfaces interfering with the heat flow. Instead‚ the water circulated around the engine is fresh water which is then itself cooled using sea water. This fresh water is

Clayton’s survival I woke up hazed with blurred vision. The right side of my face was dried and burned. The left side of my face was soaked in salt water and blood. I was freaked out and picked up my head and blinked rapidly. I saw nothing but blue for miles and miles‚ the sky and the water. When I looked down I saw nothing but a small black and orange rubber dingy. I tried to think about what had happened. It was then when I realized I couldn’t even remember my own name. Then panic just settled

THE OSMOREGULATORY ABILITY IN PHASCOLOSOMA LURCA AND UCA COARCTATA Abstract Phascolosoma lurca (P. lurca) and Uca coarctata (U. coarctata) species and their organs were examined and studied to determine their osmoregulatory ability using the density of extracellular fluid (ECF) as a measure of ionic and osmotic concentration. Body fluids are denser than water which has a specific gravity of 1‚ plus solutes. Through the examination of the two organisms‚ P. lurca is an osmoconformer and U. coactarta

University of Bahrain College of science Department of biology The Effect of Salinity on Seed Germination 1) Abstract: Poor seeding growth can be the result of soil salinity. A study was done to examine the influence of NaCl salinity treatment on the germination and seeding grow of vigna radiata using different NaCl concentration 0 (control) ‚ 0.25 ‚ 0.5 ‚ 1.0 ‚ 1.75 . A graph was used to analyze the data obtained from the study. Important differences among the treatment

Once known as the number one agricultural county in the nation‚ Los Angeles County houses nearly 10 million residents. This means the demand for consumable water is high‚ and with this demand comes depletion. Many areas of the Central and West Coast Basins are experiencing ground water depletion‚ which has resulted in an intrusion of saltwater in coastal aquifers‚ “natural filters that trap sediment and other particles (like bacteria) and provide natural purification of the ground water flowing through
