What are the names of the species used in this experiment? Which of these species was the most tolerant of increased acidity in the aquarium? Which species was the least tolerant? The names of the species used in the experiment were clam‚ dragonfly‚ and side swimmer. The specie that was the most tolerant was the dragonfly and the least tolerant was the clam. Describe how acid precipitation affects ecosystems. Acid precipitation affects the ecosystem‚ for example‚ lowering ph in water when it

Part 1. Cellular Respiration Prarthana Minasandram Partner: Ben Liu Introduction Purpose: To examine the rate of alcoholic fermentation using various carbohydrates. Hypothesis: If the yeast is placed in 5% glucose or sucrose solutions‚ then carbon dioxide production will increase over time. If boiled yeast is placed in a 5% sucrose solution‚ then carbon dioxide production will remain constant. Variables Independent variable: Carbohydrate solutions (5% solutions of glucose and sucrose) and

Cellular Biology Lab – Homework #3 Due to the week of Nov. 10-14th You may use the lab manual‚ pre-lab lectures‚ and credible internet resources‚ however you may not use your cell bio lab classmates as a resource. You will most likely see this material again on the Final and I highly encourage you to work individually and seek help from myself or your TA.Plagiarism will result in an automatic zero. 1. [15pt]In the cell bio lab‚ we use company manufactured gels‚ however you can make you own polyacrylamide

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

Glycolysis a series of biochemical reactions in which one glucose molecule is oxidized into two pyruvic acid molecules and a small amount of adenosine triphosphate (ATP). Generation of high energy molecules are used as cellular energy sources in aerobic and anaerobic respiration. The products formed through glycolysis usually enter into the citric acid cycle and the electron transport chain to produce more energy. Fructose enters the glycolytic pathway through the liver or skeletal muscle. For example

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
