Observance of Artificial Selection: Technical Study of Wisconsin Fast Plants 5th and 6th period AP Biology Due: 12/16/13 Abstract This experiment 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

Question 1 What are probable sources of acid precipitation in your community? What impact can this have on the environment in your region? Some of the probable sources of acid precipitation is Fog‚ and rain. During the summer it hardly rains which makes it hard for our crops to grow‚ also since we are in the valley it makes it hard for us to get the water that we need. During the fall it gets very foggy in the mornings and it makes it very difficult to see while your driving. Prevailing

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

sciences. Demography presents population data in‚ a systematic manner. Its importance could be gauged from the growing application of population figures in several disciplines of study. Its significance to the individual and society hardly requires any emphasis. In the recent decades population is multiplying by leaps and bounds. This phenomenon is having its impact in every sphere of human life‚ more particularly in the Social and economic life of the society. Significance of demography in different
