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

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

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

It may be frustrating when a tired person gets into bed and remembers he had forgotten to switch the bed light off. The project ‘automatic night lamp with morning alarm’ helps avoid this problem by switching on an LED itself when it detects darkness in the room. The LED serves as a bed lamp or a reading lamp

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

Heat and Temperature: Compare and Contrast Introduction to Science - CSI 110 Katherine B. Williams-Robinson Strayer University Professor Valery Shemetov February 11‚ 2011 HTC 1 Abstract It is important to know the difference between heat and temperature. It will lead to a clearer understanding of energy. In this paper‚ I will define both terms and hopefully

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

Investigating the effect of temperature on plant cell membranes The purpose of this activity is: • to practise experimental and investigative skills • to investigate the effect of temperature on cell membrane structures Procedure SAFETY: Always carry scalpels clasped to a tile and with the tip pointing away from you. Beetroot cells contain pigments called betalains that give the tissue its dark purple-red colour. The pigment is contained in the cell vacuole. Investigation

CALIBRATION OF TEMPERATURE AND PRESSURE SENSORS Mechanical Engineering Department Loyola Marymount University Los Angeles‚ California ABSTRACT In this laboratory experiment‚ an Omega Model PX- 236-060GV piezoresistive pressure transducer was calibrated‚ by using an AMTEK model deadweight pressure tester. For the temperature calibration an Jofra Model C-140 temperature calibrator was used. The experiment began by setting up the Jofra Model C-140 temperature calibrator‚ and taking data from
