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

Joshua Annan Biology Section-04 Diffusion and Osmosis December 14‚2012 Alexis‚ Adiba‚ Elliot and Joey Purpose: The purpose of this lab is to get a better understanding of osmosis and diffusion in molecules. We will do this by studying different solutions and how they move through the permeable membrane. Hypothesis: The three different possible predictions were the lab were that the mass would stay the same‚ the mass will increase‚ or the mass will decrease

Osmosis and Diffusion During the past few weeks in my Ag Biology class we have been learning about and reviewing both osmosis and diffusion. We did two different labs‚ one on osmosis; the other on diffusion. The first lab we did was our diffusion lab. We learned that diffusion is moving something from an area of high concentration to a low concentration. We were showed that Mio and other flavor drops perform diffusion when put in water as an example. For the lab part we put a mixture of starch

b 1 Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally

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

Science Research Paper: “Potato Battery” I. Problem a. Main Problem This study aims to prove whether fruits and vegetables are good reserves of electricity. The potato‚ known for its high Phosphoric Acid and Sulfuric Acid‚ has been as our chosen fruit to prove and conduct our answers upon the accessibility of fruits and vegetables as an effective renewable energy source. b. Sub-Problems To further provide extra and specific information‚ the researchers have decided to add the following

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

Group 2 Science Investigatory Project I Title: Potato Battery II Objective: We only need a potato‚ a couple nails and a piece of wire to make a potato battery. It’s a fun science project that helps show the way things work in a battery by using everyday items we see around the house. The goal is to learn more about electricity‚ and possibly a few new science terms along the way. III Materials: * Two Potatoes * Two short pieces of heavy copper wire * Two common galvanized nails
