Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate

The Anthelmintic Property of Methanolic and Ethanolic extract of the Kulitis leaves (Amaranthus viridis) Chapter 1 Introduction The World Health Organization estimates that a staggering two billion people harbor parasitic worm infections. Parasitic worm also infect livestock and crops‚ affecting food production with a resultant economic impact. Despite this pevelance of parasitic infections‚ the research o the Anthelmintic drug is sparse. According to the WHO‚ only a

nitrogen and halogens – elements that are most of the time the only ones involved in organic compounds. The experiment focused on the Sodium Fusion test‚ which tested for all elements except oxygen. In the test‚ the test compound is broken down into its elements‚ which then bond individually with sodium. The presence of sulfur was tested either with lead acetate or sodium nitroprusside. The presence of nitrogen was tested with ferrous ammonium sulfate and potassium fluoride. The presence of any halogen

The Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying

Section 623 Abstract To examine the effectiveness of buffers by titrating two sets of five different solutions using HCl and NaOH and monitoring the pH change of the various solutions. The data collected shows that the buffer systems made with sodium acetate and acetic acid were effect when titrated with the strong acid and the strong base. Comparison of all the solutions shows that the concepts of buffers holds true for the results from the experimentation. Introduction The main objective

Corporate Healthcare and Social Responsibility Genesis Burkett was born on September 26‚ 2010 three weeks before the expected date. During his admission to the Neonatal Intensive Care Unit he was administered sodium intravenously in a dose 60 times normal. As a result‚ blood tests that day indicated abnormally high levels; these were brought to the attention of the physician. The doctor ordered him checked but eight hours later‚ nothing had been done in response. At the age of six weeks
