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

Determining the Effect of Light Intensity on Photosynthesis Avalon Pernell‚ et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away

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

BACTERIAL TRANSFORMATIONS USING PVIB II. INTRODUCTION Transformation is the manipulation of a bacterial cell’s DNA in order to alter the cell’s genotype or phenotype by absorbing free DNA from its surroundings. In this lab‚ pVIB plasmid will be used. A plasmid is a segment of DNA that can incorporate itself into the bacterial DNA. Although is not required for growth of the bacterial cell‚ plasmids can provide advantages in stressful environments such as the ability to adapt as environmental

term. At the same time the concentration of H2O becomes greater‚ but because it is so large to start with (about 55.5M)‚ any effect this might have is negligible‚ which is why no [H2O] term appears in the equilibrium expression. For a reaction such as CH3COOH(l) + C2H5OH(l) → CH3COOC2H5(l) + H2O(l) (in which the water concentration does change)‚ dilution will have no effect on the equilibrium; the situation is analogous to the way the pressure dependence of a gas-phase reaction depends on the number

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

Salt Pollution As awareness for pollution increases‚ other forms of pollution are defined. Almost everyone knows about toxic waste and carbon dioxide pollution‚ but not many people have heard of salt pollution. Salt pollution has been on the increase since the evolution of the automobile. With more pressure on government agencies to keep the highway clear and safe‚ an increase in the use of salt has developed. It is important to understand why salt is used and how it work as well as the environmental

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

Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis
