Title: The Effect of Nicotine on the Heart Rate of the Lumbriculus Variegatus Introduction: Background- This lab is being done to demonstrate the effects of stimulants on the circulatory system of blackworms. In this lab‚ the stimulant we have chosen to use is Nicotine. A stimulant is an agent that causes increased activity‚ especially in the nervous or cardiovascular systems. In this lab‚ we will put blackworms into the Nicotine to look at the differences in pulse rates when compared to a control

Abstract The major objective of this experiment was to observe the effects of catalase under varying controlled conditions. The scope of this experiment includes Metabolic processes‚ such as cellular respiration‚ and it poisonous byproduct hydrogen peroxide. The methodology includes procedures; multiple variables were tested in specific concentrations; that test the reaction rates of the enzyme catalase over a fixed period of time. The major conclusion was that catalase reacts faster in warm temperatures

Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a

The objective of the deicer lab was to successfully conduct experiments to determine the usefulness of magnesium chloride as a deicer. To find how successful magnesium chloride is as a deicer‚ experiments were conducted to determine the freezing point depression‚ enthalpy of dissolution‚ the impact on the surrounding environment‚ and also the expenses of using magnesium chloride as a deicer. For magnesium chloride to be determined as a good deicer‚ the reaction with water needs to be exothermic so

Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

William Perez Cell Biology 2440 Lab on protein Myosin Proteins are chains of amino acids that perform the most important functions in living organism. Every protein will contain an amino group‚ carboxyl group‚ a different R group and an alpha carbon with two hydrogens. There are nine types of functions proteins can have‚ enzymes‚ motor‚ receptor‚ structural‚ storage‚ transport‚ signaling‚ and special purpose proteins(antibodies). There are four levels of protein structure‚ primary‚ secondary

Introduction There are two groups of reflexes in the human body‚ with two ways to categorize each of them. Reflexes can either be inborn and connected through the nervous system‚ or they can be learned through practice. Another way to explain a reflexive category would be autonomic reflexes or somatic reflexes. Autonomic reflexes are those which are unaware to us and act on visceral organs of the body‚ whereas somatic reflexes involve skeletal muscle stimulation. Both types of reflexes are put into
