Design Experiment to investigate the effect of the concentration of Sodium Hydrogen Carbonate on the rate of photosynthesis using Cobomba plant. Aim: The aim of the experiment is to investigate the effect of the concentration of Sodium Hydrogen Carbonate (NaHCO3) on the rate of photosynthesis using a Cobomba plant. Hypothesis: As the concentration of NaHCO3 increases the rate of photosynthesis of the Cobomba plant should increase‚ as there is a greater presence of a carbon dioxide‚ obtained

Cellular Respiration My hypothesis for the germinated pea experiment was that the level of aerobic respiration would increase as the temperature would increase. I also predicted that there would be an upper temperature limit. The experiment proved part of my hypothesis correct and part of it incorrect. I was correct in predicting that the rate would increase as the temperature increase‚ but I was incorrect in hypothesizing that there would be an upper limit. My hypothesis for the larvae experiment

What Affects the Rate of Evaporation? Aim * To find out if changes in temperature‚ draught and surface area of water open to air affects the rate of evaporation through the water. * To safely check if these variables change the rate of evaporation * To complete all the experiments in the short period given Prediction * I believe that a raise in temperature will speed up the rate of evaporation in the water * I believe that a larger surface area will speed up the rate of evaporation

Cellular Energetics: The Rate of Cellular Respiration and Photosynthesis over Time Among Various Variables By: Ethan Barnett Introduction Cellular Energetics is the broad term that encompasses both cellular respiration and photosynthesis and refers to how energy changes and reacts within cells. Cellular respiration is the process by which cells break down sugars (ATP) in order to produce energy for other chemical reactions. Cellular respiration takes place mainly in the mitochondria and the reactants

Gas exchange in animals External respiration: not to be confused with cellular respiration‚ although purpose is to provide oxygen and eliminate carbon dioxide Single-celled organisms achieve this by simple diffusion Larger organisms need specialized breathing organs Getting the air into the body is one challenge Circulatory system needed to distribute oxygen to the tissues Specialized blood cells can transport oxygen (solubility in plasma is very low) The process of breathing Air has much

The purpose of this lab was to gain a complete understanding around the rate of cellular respiration within multicellular organisms‚ also to research and understand how to use a CO2. Background: Living systems require free energy and matter to maintain order‚ to reproduce‚ and grow. Energy deficiencies cause disruptions at the population and ecosystem levels as well. 1 mol of H2O produces 1 mol of CO2 through cellular respiration. Autotrophic organisms capture free energy from the environment through

temperature has on the growth and respiration of yeast fermentation. The growth and respiration of the yeast can be determined by using a glucose/ yeast solution mixed with water in flasks set at different temperatures. Yeast in order to produce‚ has to make energy‚ to carry out all cellular functions (Spicer‚ & Holbrook‚ 2007). The concept that aerobic metabolism of all yeasts‚ is determined by the relative sizes of the transport rate of sugar into the cell and the transport rate of respiratory into the mitochondrion
