    In bio lab‚ my lab partners and I did a lab experiment involving yeast fermentation. Fermentation is an anaerobic process to regenerate NAD+ to keep glycolysis active. Yeast preforms ethanol fermentation which create ethanol and NAD+. The class used six different types of sugars to determine which fuels fermentation by measuring the amount the carbon dioxide bubbles produced by the yeast. Yeast are single-cell fungi that cannot make their own food. They take the sugars in the surrounding environment

    Abstract: This experiment‚ which was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism’s traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to

    Title: Creating the chemical reaction of Osmosis with an Egg. Purpose: We are taking a large single cell (the egg) and demonstrating Osmosis. Osmosis is a type of diffusion where the water molecules is the solution that is being moved. Osmosis is the movement of water through a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. Introduction: When trying to create an osmosis reaction‚ it is important to understand
