Addison Bollaert Professor Hunderman Comp 252 4/6/15 Fukushima The nuclear arms race of the 1940s gave birth to countless advancements in science and technology. A seemingly limitless source of relatively clean energy had been discovered. Nuclear power did not come without risks, as the smallest error could lead to a disaster of unimaginable proportions. The events at Fukushima served as a reminder that when . The Fukushima Daiichi disaster will have lasting effects on the environment, and the…
Scientific papers are extremely important in the field of science because of the way that they allow scientists to communicate their findings with each other. Primary literature is the most important source of information for scientists because it includes the most current reports on the topic of interest. Primary literature includes first-hand reports of discoveries and is written by scientists, with a target reading audience of both other scientists and science students. For this assignment, I…
It’s a fact: Antarctica is melting. According to researchers from Caltech, seawater surrounding the continent is slowly melting the ice. But exactly how did the warmer water come into contact with Antarctica? Using dolphin-like robotic gliders, the researchers have uncovered the answer: storm-like underwater eddies (water flows) are to blame. The paper, co-authored by Karen Heywood, Andrew Thompson, and others, sheds light on the exact process. “When you have a melting slab of ice, it can…
Cellular Death: Tonicity on Potato Cells Introduction The purpose of this experiment was to test the effects of tonicity on potato cells. During this experiment slices of a potato were placed into beakers containing salt solutions with different concentrations. How will the percentage of salt concentration in solution affect a plant cells water content? This experiment will determine which salt solution concentrate will cause the potato cells to absorb water or lose water. Tonicity in…
item they traded was luxurious purple cloth. This was very profitable because other civilizations did not have the resources to make this fine material. The phoenicians were skilled at making this fabric. The dye for the cloth was made from urine, seawater, and ink from a murex snail. The snails were boiled causing…
In particular, the competitiveness of reverse osmosis seawater desalination is highly dependent on the price of electricity. Reverse osmosis pushes water through a membrane to separate the freshwater from the salts; this requires considerable energy input. Electricity expenses represent one-third to one-half…
prevents substantial swings in the temperature. Also, water density, water temperature and salinity have significant importance in the ocean. Density of the seawater influences ocean’s structure and movement, and density is dependent on the temperature and salt content in the ocean’ water. All the water on Earth including freshwater, seawater, evaporated water, solid water are in constant motion, circulating between the ocean, the…
high pH due to the calcium carbonate in their morphology, they form these structures in a process where calcium and carbonate ions must be in excess in the seawater surrounding the corals so that they can form their carbonate tissues this process is called ‘calcification’ (3). When the pH levels are lowed the concertation of carbonate in the seawater is lowered and this weakens the calcium carbonate features in the coral as well as making it harder to form calcium carbonate…
the ocean, this is becoming an ever increasing reality. Research and experiments performed by scientists at NOAA (National Oceanic and Atmospheric Administration) have shown how the zooplankton handle the stress caused by ocean acidification. Using seawater with the projected amount of CO2 for 2100, scientists placed these two miniscule organisms into this solution and watched the results. Within 45 days the shells of the creatures had liquefied. Critics of ocean acidification down play the…
water in farming can produce many crops and also prevent shortage of it. Water is everywhere, 97% of the world is ocean but it is seawater which can not be used, on average, seawater “has a salinity of approximately 3.5%, this means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it”. Seawater is not consumable but scientists have discovered a way to make it usable and that…
