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

Chagas disease cysticercosis Parasite (Worm or protozoan) protozoan worm Effects on human host Fever‚ swelling around initial infection site‚ parasites in blood‚ sometimes asymptomatic‚ rarely debilitating or life threatening problems can occur. Formation of larval cysts can occur in the muscles‚ eyes‚ brain‚ and/or spinal cord. Cysts

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

BAEK (10Bio02) Do NOT delete anything I have written in red. Make any corrections in blue so I know what to re-read Osmosis Diffusion is the net movement of particles from an area of high concentration to an area of low concentration. Then what is osmosis? Basically‚ osmosis is the same action with diffusion but in water. To describe more precisely‚ osmosis is the net movement in water across partially permeable membrane‚ which mean the membrane allows the water to get through the

AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical

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

Melissa Morales Bios 101 Spring 2013 Demography- Human Life History Introduction Demography is the study of human populations. It studies the size‚ composition and distribution of a population‚ and the process through which a population changes. Demography allows us to track changes over time and to depict how different periods in history change population dynamics. Births‚ deaths‚ migration and emigration‚ jointly produced the change within a population (Biological Science). Demography
