December 8‚ 2013 Soil Analysis Lab Report Intro: Soil is produced over hundreds of years through the weathering of rocks and the decomposition of organic material. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Nutrients such as nitrogen are added to the soil in these ways by organisms such as nitrogen fixing bacteria. Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. Soil

For one‚ when sample size was n=3‚ there was a marked decrease heart rate for samples treated with nicotine from a basal heart rate of 147.04 bpm to a drug treated heart rate of 66.67 bpm which is contradictory to the literature and contradictory to experimental values when n=12. Nicotine is a known

Effects of Temperature and pH on Enzyme Function Chelsie Mesa Section 0479 Robin Cotter Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme

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

zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a. Research question ¿Does the quantity

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

Introduction:- The primary objective of this experiment is to determine the concentration of an unknown copper (II) sulphate solution. You will be using the colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. The CuSO4 solution used in this experiment has a deep green color. A higher concentration of the colored solution absorbs more light (and transmits less) than a solution of lower concentration. [Content Standard B- Structure
