Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Investigating a factor that affects the rate of enzyme activity Enzymes speed up reactions. They have an area with a very particular shape called the ‘active site’. When the right molecule comes along (substrate molecule) it will fit perfectly into the active site and there will be a reaction. After the reaction the products then leave the active site. This process is often referred to as the lock and key theory as only one enzyme can carry out one type of reaction. The catalase enzyme speeds

The aim of our investigation is to find out whether the use of different sugar isomers with yeast‚ will affect the rate at which the yeast respires at. The sugars to be tested are fructose‚ galactose‚ glucose‚ lactose and sucrose. Their effects on the respiration rate of yeast to be observed through the measurement (cm3) of the displaced water‚ which will tell us how much CO2 has been respired over 2 minutes. To compare the effects an average will be calculated for each and a result will be drawn

the acid in lactate acid‚ it interfere with electrical signals in muscles and nerves‚ slows energy reactions‚ and impairs muscle contraction. The burn up we feel in intense exercise is the cause of hydrogen ion. During this experiment(Muscle fatigue lab) it will be seen that after a while of squeezing a small ball there won’t be the same amount of energy that was started with first and you will feel a burn in your arms which makes you feel hurt and don’t do a lot of squeezing; which is called the

Lab Report 1708 Mrs. Himler Ryan Nelson 9/20/2024. Lab Report INTRODUCTION: During this lab‚ the group used 3 food thickeners. These thickeners are used to thicken‚ stabilize‚ and prevent separation for our daily products such as ranch‚ ice cream‚ and other dairy products. The group used modified food starch‚ corn starch‚ and guar gum. They all are different from each other‚ each in a unique way. Firstly‚ guar gum is like pectin‚ a soluble fiber and polysaccharide. Furthermore‚ the body cannot digest

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

The clinical formula of Equal was not metabolized because it has no sugar. Splenda is actually derived from sugar so the results would be different. 2. Carbon Dioxide was the gas that was produced. Two methods would be by examining the bottom of the tube and to measure the net difference. 3. The

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity
