Aim: 1) To determine the effects of different salt concentration on the percentage of weight change in potato cubes 2) To determine the isotonic solution concentration for the potato Hypothesis: 1) If the concentration of the salt solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through

presence of a catalyst which‚ in this case‚ was 85% phosphoric acid. Dehydration can be defined as any chemical reaction which involves the removal of a water molecule from a substance. During the experiment‚ anhydrous calcium chloride was provided as a drying agent to ensure that pure cyclohexene was obtained‚ calcium chloride works by binding itself to the water molecule thus removing it in the process. After the dehydrating process was completed‚ a few tests using Potassium Permanganate solution and

Climate change and tropical biodiversity: a new focus Brodie J.‚ Post E.‚ Laurance W. In this review article‚ Brodie et al. expose a different approach to looking at the effects of global climate change on tropical biodiversity. An abundant amount of literature does‚ in fact‚ address the direct effects of climate change on biodiversity in the tropics. Brodie et al. argue‚ however‚ that while these efforts are extremely important and notable for current and future conservation efforts‚ little
