Succession Lab INTRODUCTION: The purpose of our lab was to begin to understand the rates of succession. Succession is a number of persons or things following one another in order or sequence. Considering that all living things follow some sort of order‚ Joey Collins‚ Brian Carman‚ Chris Broadwater‚ Marisa Grondin‚ and I attempted to figure the succession rates of two different forests. In order to do this we used the forest behind the elementary school and the forest behind the track‚ by the

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

In general‚ there is always human error. This could cause measurements to be off a bit‚ timing to be too long or too short‚ or even recorded data to be mistaken. Also‚ perhaps the test tubes did not incubate in the water baths long enough or maybe too long so the temperature was not

Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report‚ we discover the most effective disinfectant that would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly

spices were often used to provide a rich yellow color to various foods. Butter has been colored yellow as far back as the 1300s. Food color additives are dyes‚ pigments or substances that impart color when applied to a food‚ drug‚ cosmetic‚ or the human body. The Food and Drug Administration (FDA) is responsible for regulating all color additives used in the United States. All color additives permitted for use in foods are classified as "exempt from certification" or "certifiable". Color additives

Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At

I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

Executive Summary Caffeine is a stimulant for the central nervous system which will relax the muscle and increase the gastric acid and heart rate (Kelly‚ 2017). The analyzing of caffeine and caffeine metabolites in saliva is to quantitatively measure the ratio of concentrations of caffeine and metabolites. There are three different metabolites of caffeine and the majority of caffeine metabolite is paraxanthine. The ratio of concentration represents the activity of the first metabolism enzyme of caffeine
