This occurs because these forests are exposed to cold and warm air‚ which makes them encounter all four seasons. Temperatures in the deciduous are estimated to be up to 50°. They also have precipitation of 30 to 60 inches a year. One of the traits these trees have is thick bark that protects them from cold or really hot weather. Deciduous forests can be found everywhere

Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected

Barley Alpha Amylase with Starch at Specific pH ’s and Temperatures Page 1 Abstract Enzyme ’s are used as catalysts in certain reactions. They help lower the activation energy needed for the reaction to go to completion. At optimum temperature and pH the amount of collisions of substrate and enzyme is at its highest‚ any deviation from the optimum temperature and pH will result in the denaturization of the enzyme. The purpose of this experiment is to find the optimum temperature and pH for

Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all

To investigate the effect of temperature on an enzyme controlled reaction Introduction and planning For the investigation of enzymes‚ I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch. The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions‚ we can record the rate of reaction by taking a

In the novel Catalyst by Laurie Halse Anderson‚ there are three main sections‚ Solid‚ Liquid‚ and Gas. The main character‚ Kate‚ is very interested in science and the three titles are a metaphor for her state of mind throughout the book. The first section‚ Solid‚ shows how Kate is a stable and strong person. The next section‚ Liquid‚ is a time where Kate’s life is very inconsistent and she is unsure about herself. The last section‚ Gas‚ shows how Kate has accepted her fate and tries to help everyone

Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is

Continental Temperature Ranges Introduction: There are large variations in average monthly temperatures among cities located at the same latitude. This suggests that factors besides the angle and duration of isolation affect the rate heating and cooling of any given location. Objective: You will graph the average monthly temperatures of costal and inland continental regions and interpret the range in temperatures. Vocabulary: Temperature range- Average daily temperature Average monthly
