The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

Liquid or fluid appearance is visible. Bacteria and background don’t have a much of difference in color. Although‚ bacteria are defined and visible noted. Most of the time they are single round cells. In direct stain with crystal violet‚ again background is colorless and glossy. Bacteria is blue and some

The Effects Different Types of Water Have on Plant Growth Abstract This experiment examines the rate of plant growth when watered with different solutions. Throughout the course of a nine week period‚ five lima bean seeds were watered with five different solutions to see which will most enhance the growth of plants. The five solutions consisted of distilled‚ filtered

of my microbiology class at Brunswick Community College. This journey started out with a media plate cultured with an unknown species of bacteria. I was then instructed by my professor to use all of my previous knowledge to identify the unknown bacterial pathogen. This lab led me to master my skills of using the Gram stain‚ testing for catalase‚ testing for coagulase and using the oxacillin screen. Now I am going to take you with me on the journey to the unknown. As I recall from earlier that

BIOLOGY PRACTICAL ASSIGNMENT NAME OF INVESTIGATION: Effect of Eutrophication on Plant Growth RESEARCH QUESTION: How does the process of Eutrophication affect the growth of Duckweed? HYPOTHESIS: In this experiment‚ we are basically testing the use of different fertilizers on the growth of Duckweeds. Plants need fertilizers for their growth and to increase the yield of crops. But‚ at the same time‚ it depends on which Fertilizer being used and in how much proportion. Does it have sufficient nutrients

This study focuses on the effect that temperature has on the enzyme amylase. Enzymes are composed of proteins and acts as a catalyst to speed up the rate of a specific chemical reaction by lowering the activation energy. Reactions do not need enzymes to occur‚ but the human body and other living organisms depend on the use of enzymes in order for biochemical reactions to happen in milliseconds. Each enzyme contains a distinct three dimensional structure which is related to its particular function

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature
