The Spectrophotometer Determination Of Protein Concentrations And The Effects Sodium Dodecyl Sulphate And Triton X-100 Have On Protein Concentration. INTRODUCTION Spectroscopy is used as a collective term for all the analytical techniques based on the interaction of light and matter. Spectrophotometry is one of the branches of spectroscopy where we measure the absorption of light by molecules that are in a gas or vapour state or dissolved molecules/ions (Tombs‚ et.al‚ 1959). Spectroscopy is the

Introduction Why: The goal of this experiment is to determine the water hardness of the prepared unknown water sample. Determining water hardness is a useful test that measures the quality of water for its household and industrial users. Water’s hardness arises from the presence of metal ions – specifically metal ions with a charge of +2 or higher. The ‘scum’ left over in a cleaned shower stall or coffee pot is equivalent to water hardness. Water dissolves salts which contains ions of sodium‚ magnesium

Abstract: Ultraviolet (UV) radiation and its detrimental effects on plant life have been widely researched. This research studies the effects of UV radiation on sex-determination in Ceratopteris richardii. Sex determination in Ceratopteris richardii is determined by antheridiogen‚ a pheromone that promotes maleness. In this experiment‚ UV radiation was used on the wild type and mutants Her1‚ which are insensitive to the male-inducing pheromone (does not form male gametophytes). Ceratopteris richardii
