amount of ATP the seed can generate in order to grow‚ the temperature of the environment and the amount of sunlight the seed receives (Ghaderi-Far et al.‚ 2010). The purpose of this study was to observe the effect of different concentrations of sodium chloride have on the germination of lettuce seeds‚ Lactuca sativa. A study done by Katembe et al.‚ (1998) stated that an increase in salt solution in the environment of the seed will slow down water imbibition‚ therefore‚ preventing germination and root growth

relation to this dilemma. Past research has shown that hydrogen fuel cells can quite possibly replace the country’s current usage of oil while having a more positive effect on the environment. However‚ environmentalists have conducted their own contradicting research on fuel cells reflecting negative effects on the environment. Numerous articles have been published which express both sides of this debate. Although some scientists believe hydrogen fuel cells will improve the environment and rid the United

Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity. Hydrogen fuel

Decomposition of Hydrogen Peroxide by Potassium Iodide Brief Description: Two solutions are mixed resulting in an eruption of foam resembling a huge stream of toothpaste. This is the classic “Elephant Toothpaste” reaction. Purpose/Goal: Procedure presents an example of a catalyzed reaction. Explanation of Experiment: The rapid evolution of oxygen gas is produced by the following reaction: 2 H2O2 (aq) = 2 H2O (l) + O2 (g) + heat The decomposition of hydrogen peroxide in the presence

EXPERIMENT 1: Aim: To range the metals copper‚ lead‚ silver and zinc together with hydrogen. Start with the strongest reducing agent. Hypothesis: The nobler a metal is‚ the worse reducing agent. Apparatus/requirements: Sandpaper‚ strips of; zinc‚ lead‚ silver and copper‚ solutions containing aqueous; Zn2+‚ Pb2+‚ Cu2+ and Ag+ ions (0.2 M)‚ hydrochloric acid (5.0 M)‚ emery paper‚ test-tubes. Method: Burnish the three metal strips to get a shiny surface‚ after drop a drop of each of the metal

13 Principle of Asepsis The 13 Principles of asepsis is a basic knowledge that a nursing student should always remember when preparing for an operation and when working during an operation. Since Asepsis means the absence of pathogens‚ these 13 principles of asepsis is not only applicable when there is an operation but it should be observe in situations where there is a need to maintain the sterility of certain articles and to maintain a sterile environment. 13 Principles of Asepsis 1.

Fracking: Underneath the cracked shell Recently in the Coal State‚ aka Kentucky‚ a new way of getting oil has come. Fracking has become more and more popular in the US and in the world. Fracking consists of drilling‚ and cracking into the ground vertically and horizontally. This new method uses water pressure and thousands of chemicals to pump the oil to the surface of the land. As a resident in Kentucky‚ I leave around some empty land out in the country side. Recently‚ I heard about KGA (Kentucky
