component of the Rosetta spacecraft with a spotty service record. The Europeans are now hopeful of retrieving new imagery and data on drill samples as soon as communications are restored. WHY DOES PHILAE PERFORM BADLY? This may be a misrepresentation of the facts; Philae was impeccably designed, and is fully capable of performing its duties, but upon beginning its final descent last November, the lander had a few issues, bounced on the surface several times, and came to rest in a small valley. Since

of a substance into a new one that has a different chemical identity (Chemical Reaction , 2015). It rearranges the atoms of the reactants to create different chemical elements or compounds. Chemical reactions occur because an atom is trying to get a full outer shell of electrons. A chemical reaction is usually accompanied by easily observable physical effects such as the emission of heat and light, precipitate, gas and colour change (Factors that affect reaction rates, 2015). When a chemical reaction

velocity, acceleration and time displacement over the 100m sprint. We used Bolts world record time of 9.58s from the Berlin World Championships in 2009 and the amateur athlete’s time of 12.79 which we gained from carrying out a lab experiment. We then input both sets of data to create graphs to easily identify the similarities and differences between both athletes. Introduction In 2009 Usain Bolt set the world record time for the 100 metre sprint at the Berlin World Championship. This would be the third

which drag the surface water westward and raise the thermocline relatively all the way up to the surface in the east and dampen it in the west. During El Nino conditions, however, the easterlies move east, reducing the continuing interaction between wind and sea, allowing the thermocline to become nearly flat and to plunge several feet below the surface of the water, allowing the water to grow warm and expand. With the help of the National Oceanic and Atmospheric

aplant cell control its turgor pressure Hypothesis Part One If the NaOH, phenolphthalein, agar cubes are put into 0.1M HCl solution, then the largest cube will have the fastest rate of diffusion, as it has the most surface area, and therefore the largest change in volume and surface area. Part Two If the cell and the solution

increase in specially carbon dioxide, increases the infrared energy taken in by the atmosphere, and warming the earth's surface. The Global mean temperature over the past 150 years has risen between 0.3 degrees C and 0.6 degrees C. Climate changes that have been predicted are based on the continual rise in Green House Gases. These changes include changes in: increase in mean surface air temperature,

Roles of the Registered Nurse (RN) are ever changing where it is key to continue to educate for the protection and well being of the patient. Pressure ulcers have become a main issue in healthcare in an attempt to lower cost as well as prevent further morbidities and complications for the patient. According to the National Institute of Health (NIH) a pressure ulcer is defined as an area of skin that breaks down when something keeps rubbing or pressing against the skin. An increase in immobile and

photosynthesis process. As reported by Union of Concerned Scientists that CO2 today are 25% higher than in 1957. Due to the releasing of CO2 and chlorofluorocarbons to the atmosphere that lead to ozone layer depletion, more sunlight is passing to the earth surface. In addition, the natural disaster has the role in rising the temperature, for example: volcanoes. This essay will state the scientific problems of climate change and how it threatens the life of organisms. Also, it will suggest solutions for this

bung placed on top because this will stop anything from entering and leaving that may affect the investigation. A tube will then go from the bung to the bee hive shelf; this will be under the water. On top of this will be a measuring tube that will be full of water because when the gas bubbles come up the water will decrease, giving me the amount of gas given off. •Then weight 2.0g of medium sized marble chip and 25 ml of substance. •Prepare to start stopwatch put marble chips in with acid & put bung
