The effect of salt concentrations on the mass of the pear cubes ‘Pyrus’ after being soaked in water Aim: The effect of salt concentrations on the mass of the pear ‘Pyrus’ pieces shaped as cubes of 1cm. Background: Osmosis is the net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential. Water makes up to 70-90% of living cells and cell membranes are partially permeable membranes. Dissolved substances attract

OBJECTIVE: The experiment was carried out to investigate the effects of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different

myself from media for 8 straight hours‚ my first thought was that it was going to be impossible. Although it was hard at first to completely cut myself off of what was so predominant in my life‚ it was in fact possible. My first hour of the deprivation started around one o’clock in the afternoon. To start things off my boyfriend‚ Chris‚ and I made ourselves a delicious lunch. We made ham and turkey sandwiches with cheese‚ lettuce‚ and tomatoes on a toasted whole wheat bread with honey mustard

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

Sleep deprivation has become a major problem with Americans. Over 100 million Americans today suffer from lack of sleep. This has been an ongoing problem throughout the centuries. People owe their bodies sleep and scientist are calling it a "Sleep debt". An average American owes their body at least thirty hours of sleep. This lack of sleep is as hazardous as drunk driving. One man caught sleep deprivation at it’s best. He pushed himself to the limits as much as possible. One day he went

The effect of nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked

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
