Why does the colour leak out of beetroot? Procedure to investigate the effect of temperature Hypothesis- The higher the temperature while cooking the beetroot‚ the more pigments well leak out from the cell membrane‚ hence the absorbance would increase. My hypothesis was concluded by the facts that beetroot contains red pigments called betalians which are located in the cell vacuole. Normally the pigments cannot leak out; however cooking the beetroot allows the movement. This is because the cell

Methods We began this experiment by turning the Spectrophotometer to 605 nm absorbance‚ and setting up each of the tubes as stated in Table 7-2*‚ ignoring the DPIP until the rest of the sample was set up. Once all of the samples were set up accordingly‚ we blanked the spectrophotometer‚ and added the DPIP to the sample right before‚ inverting the sample and taking a reading at the Zero time mark‚ and placing the sample in the designated light apparatus‚ Sample 1 was wrapped in aluminum foil to

are exposed daily to oxygen (such as fruits‚ vegetables and animals). Background Information The Catalase enzyme in this experiment is known for being less affective the warmer the temperature is. According to “Science fair projects” an enzyme becomes unstable at higher temperatures and the shape of the enzyme changes. The enzyme is also used to remove hydrogen peroxide from clothing in the textile industry. This would make sense because when an enzyme encounters a substrate molecule

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

How does lava temperature impact viscosity and velocity? The higher the temperature the lower the viscosity which allows it to develop a smooth surface skin‚ but this is quickly broken up by flow of molten lava‚ it creates a rough‚ clinkery surface. The lower the temperature of the magma the higher the viscosity which allows the lava to travel down the slope. In the group the average velocity was 0.91 cm/s . How the “lava” flowed was in a high viscosity and a low velocity because the “lava” was

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

Two experiments were performed to investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1.

discussion of the enzymes reaction to heat will be addressed. Does heat speed up the enzyme reaction? The prediction is as more heat is applied more reactions will occur then at some point the heat will denature the enzyme as it reaches too high of heat. If an enzyme has been denatured it means the shape has been altered therefore cannot perform its function‚ many factors can cause this including high heat. The hypothesis is if temperature is increased the amount of activity rate will increase. The

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable
