AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

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

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
