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

LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

he is too strong.” People constantly told me to expect the worse‚ however‚ I knew that he would pull through and beat cancer. My dad had always been there for me while I was growing up‚ at that moment I knew it was my turn to be there for him. Perseverance is by far one of my dad’s most admirable qualities. My dad has gone through multiple ups and downs during his life‚ and he treated cancer as just another curve ball life threw at him. He understood that cancer wasn’t just affecting him‚ it was

It can be inferred that Rainsford was very afraid of Zaroff. He was also afraid of dying. However‚ Rainsford preserved and kept himself together. Rainsford actively participated

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

by the concentration of starch‚ or whether the results I got were due to the amounts of solution used. This would make both my results and conclusion invalid and unreliable. I also made sure that the temperature of the water bath was at the correct temperature and I kept on checking the temperature of both my amylase‚ and starch using a thermometer. I made sure both solutions were at the same temperature at all times throughout my experiments‚ so that temperature would not have an effect on my results

Title of investigation: The effect of solute concentration on osmosis in potatoes. Research question: What is the solute concentration of a potato? Hypothesis: Osmosis is the movement of water across the membrane from an area of high concentration to an area of low concentration. The osmosis continues until the solute concentrations are equal in both areas. In this experiment‚ we put pieces of potatoes into test tubes with sugar solutions of different concentrations and leave them there over night
