Measurement and Uncertainty When recording data‚ each entry should be given a corresponding estimated error‚ or uncertainty. The uncertainty gives the reader an idea of the precision and accuracy of your measurements. Use the following method for finding the uncertainty associated with any measuring device used in lab. First‚ find the least count‚ or the smallest printed increment‚ of the measuring device. On the meter sticks‚ the least count is 1 mm. On the double pan balances‚ the least count

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

Introduction Human cilia play a critical part in human processes. Human cilia are hair-like projections that extend from the surface of a cell. Cilia are capable of rhythmic motion and acts together from separate strands so that the cell is capable of movement. Flagella are a whip-like structure that is found in cells as well that allow for the movement of the cell. Human cilia are characterized as having “metachronal rhythm" and this means is a rhythm that "changes time" to produce wave. The beating

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

A company has specified that the acceptable size of a knob that is to be produced is (0.140 ± 0.003) inches. In this lab‚ the dimensions of the knobs produced in one day are tested for discrepancy in order to pass control testing. This lab also reports the probability that knobs with the acceptable dimension will be produced. MATERIALS AND METHODS Using Microsoft Excel‚ a histogram was created displaying the three documented dimensions of 15 batches of knobs. This histogram was obtained in order

University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

For information on how this assignment will be graded‚ please visit the Course Information sectionChlorophyll and Accessory Pigments A pigment is any substance that absorbs light. The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes
