An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

After a holding period of 18 hours for winter captured crabs and a period of 30 hours for summer captured crabs‚ all individuals were transferred to containers with experimental temperature and salinity levels to begin the experiment. To observe changes due to salinity concentrations over the 48-hour period‚ groups of crabs were exposed to one of the eight salinity treatments‚ and temperature treatments were held constant at 5°C or 15°C to resemble winter or summer field conditions

ABSTRACT Gi-Fi will helps to push wireless communications to faster drive. For many years cables ruled the world. Optical fibers played a dominant role for its higher bit rates and faster transmission. But the installation of cables caused a greater difficulty and thus led to wireless access. The foremost of this is Bluetooth which can cover 9-10mts. Wi-Fi followed it having coverage area of 91mts. No doubt‚ introduction of Wi-Fi wireless networks has proved a revolutionary solution to “last

OBJECTIVES To demonstrate the effects that a bypass capacitor has on amplifier voltage gain (Av). To demonstrate the ac operation of the common-emitter (CE) amplifier. INTRODUCTION A common emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies‚ typically used as a voltage amplifier. In this circuit the base terminal of the transistor serves as the input‚ the collector is the output‚ and the emitter is common to both. The input signal to a

The testing for the Doll Test OR Eye Color Experiment resonated more with children is because children are brought up in discrimination house hold. Doll test told that how equal size the dolls were except for their color‚ to test children’s racial perceptions. Their subjects‚ where at least the children between the ages of three to seven‚ were asked to identify both the race of the dolls and which color doll they prefer. Eye Color Experiment talks about on how children treated each other by eye color

Abstract The process of photosynthesis can be summarized as the photoautotroph consumption of carbon compounds as food and release of oxygen compounds as waste. The methods to measure the rate of photosynthesis are various. One method utilizes CO2 sensors to measure photoautotrophs CO2 intake under various luminescent environments. An elementary method utilizes H2O and NaHCO3 (Sodium Bicarbonate) for submersion of deoxygenized photoautotroph specimens to measure the release rate of oxygen compounds
