Aim: In this investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot

MIC Practical Report Kerry Haarhoff 18 April 2012 3150540 Introduction Bacteria and fungi are both micro-organisms‚ however‚ fungi are spore-producing organisms whereas bacteria are not and fungi can be multicellular and bacteria is only a unicellular organism. These 2 micro-organisms‚ along with many other things circulate in the air within our environment. These micro-organisms then settle and become more prevalent in different areas. An experiment was conducted to see where

Biochemistry CP2085 Effect of Temperature‚ Study and Measure of Enzymes Activity Abstract This experiment investigates the effect that temperature has on the rate of activity of enzyme β-galactosidase and also the rate of β-galactosidase activity in different concentration of substrate over time. Ο-nitrophenylgalactoside (ONPG) is used as a substrate for β-galactosidase. A spectrophotometer is used to detect the change in colour of the substrate. Results show that increase in temperature up to 50oC speeds

stability of the environment by monitoring the PH‚ temperature‚ lighting‚ and salinity. A one degree increase in temperature in a salt water fish tank could cause the fish and reefs to become ill and shocked. Therefore‚ you must monitor the heater in your tank to make sure it is functioning properly. The proper temperature in a saltwater fish tank‚ no matter how many gallons it is‚ is 77 degrees. This is because that probably the temperature the fish and coral were kept at‚ when they were at

Discussion The data demonstrates that there is a larger temperature change in the cheese and bacon balls compared to the popcorn. This temperature change of the water is due to the cheeseball having more energy due to its fats and sugars‚ therefore releasing more heat and differing the temperature more than the popcorn with the less fat and sugar. The mass of the food was consistent throughout the experiment ranging from 2.98 - 3.25‚ therefore the mass of food combusted was consistent as well. The

Causes and Effects of Advertising of Water Pollution in Lake Huron Luis Paredes Dr. Wallace ENG 115 Water Quality is very much in the news these days and it is also a growing public concern. Water is one of the most important resources on the planet and affects nearly every aspect of life. The Great Lakes watershed contains a large percentage of the world’s fresh surface water. The Lakes support the water needs‚ and jobs of millions of people and poor water quality is an increasing frustration

Introduction In this experiment‚ we will be figuring out how much does 80 degree celsius water reduce in temperature in 15 minutes‚ using different materials to insulate the heat. The five materials that will be tested are: Aluminium foil‚ plastic wrap‚ newspaper‚ felt‚ and bubble wrap. Aluminium foil is a reflective material; this means that it bounces the thermal energy back to the foiled object. It also absorbs the heat. Not only does it stop heat loss‚ but Aluminium foil is also useful for

To understand the issue of temperature control of ball mill can better finish grinding. Temperature of ball mill is big issue. Appropriate temperature must be set in production. Temperature not only affects the properties of ball mill material but also the grinding performance of grinding materials. The normal temperature of ball

Question: * What effect does temperature have on the rate of Diffusion? Hypothesis: If we put the antacid in hot water‚ then it will dissolve faster than in cold water or room temperature water. Material List: * One thermometer * 3 beakers (of the same size) * 3 antacid tablets * Cup of ice * Hot plate * Paper towels * Water Procedures: Step 1: Gather materials Step 2: Label the beaker #1‚ #2‚ and #3 Step 3: Fill each beaker with the same amount of water. Step 4:
