Andrew Reynolds October 19‚ 2012 Intro to philosophy How do you know what you know? For many years‚ philosophers asked‚ “how do we know what we know”? Socrates said that he was the wisest man alive because he knew that he did not know. He knew that it was impossible to know everything. To begin to think about how we know what we know‚ we have to first know the meaning of knowledge‚ the meaning of belief‚ and how they are different. We also have to know if it is rational to have a belief

The Effects of pH on Slime Mold Dg Nicole Harris BIOL181 – 059 1 December 2011 The theory that slime mold is attracted to acidic solutions was examined by the slime mold‚ Dg. Dg’s preference of pH was examined by using a variety of pH solutions in a petri dish. The data suggests that the growth of fruiting bodies observed in pH 9 was comparable to that of pH 4. INTRODUCTION The 2002 scientific journal‚ “The Costs and Benefits

pH and Microbial Growth Introduction: Each organism has an optimum environment for growth‚ which includes pH level. Organisms that grow at near neutral pH levels are called neutrophiles. Those that grow best in acidic pH values are called acidophiles. Others‚ yet‚ grow best in alkaline pH values and are called alkaliphiles. In this lab‚ each group was assigned an organism‚ which was then used to inoculate 6 different pH levels. Materials and Methods: Followed lab procedure 29‚ “pH and

THE EFFECT OF SALINE ON BEAN GERMINATION AUTHOR: Erik Motyka Lab-partner: MWCC Biology I-109 Professor: Dr. Atryzek ABSTRACT: The response of Phaseolus vulgaris to increased levels of saline solution at germination and seedling growth was investigated. Seeds were germinated in paper towels placed in plastic Ziploc bags with varying concentrations of saline solution and incubated at 25°C. At the end of 14 days the seeds

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

analyzing pH it measures for the acidity or basicity of a solution. pH levels vary depending on the solution. The more acidic solutions would be juices and vinegar and cleaning materials would be basic. You can determine the purpose of solutions based on their acidity and basicity. We measure the pH of solutions on a scale with levels from 1-14. These levels may change if other solutions are added‚ we can tell what the pH will be based on its colour. Solutions called buffers change the pH levels of

Red Cabbage Indicator Aim – To create a pH indicator out of a red cabbage solution and to construct a basic pH scale to determine the pH of unknown solutions. Materials - • red cabbage leaves • 250 mL beaker • hotplate or Bunsen burner‚ tripod‚ gauze mat and bench mat • 10 test-tubes – equal size • test-tube rack Methods - Part A: Making the indicator 1. Tear up one or two red cabbage leaves‚ and place them in the beaker with enough water so that the cabbage is just covered. 2. Heat the beaker

Buffers‚ and pH‚ and Diffusion oh my The pH of a solution is the measure of the concentration of charged Hydrogen ions in that given solution. A solution with a pH lower than seven is considered to be acidic. A solution with a higher pH is a base. It is very important for organisms to maintain a stable pH. Biological molecules such as proteins function only at a certain pH level and any changes in pH can result in them not functioning properly. To maintain these constant pH levels‚ buffer solutions
